Frequently Asked Questions - XDS3000 Owon

How do I calibrate the oscilloscope probes?

Connect the probe to the CAL output terminal (typically a 1 kHz square wave). Adjust the compensation trimmer on the probe until the waveform appears as a clean square wave without overshoot or rounding.

What is the maximum bandwidth of the XDS3000?

The XDS3000 has a bandwidth of 30 MHz. For signals beyond this frequency, amplitude accuracy degrades.

How can I save a waveform to a USB drive?

Insert a USB flash drive into the USB Host port. Press the Save/Recall button, select Save to USB, choose file type (e.g., CSV, image), and confirm.

Can I measure the frequency of a signal automatically?

Yes. Press the Measure button, select Add Measurement, choose Frequency from the list. The value will be displayed on screen.

What should I do if the screen is frozen or unresponsive?

Perform a factory reset: press and hold the Menu button while powering on. If that fails, disconnect power, remove the battery, wait 10 seconds, then reconnect.

How do I use the XY mode?

Press the Display button, select XY Mode. Channel 1 drives the X-axis and Channel 2 drives the Y-axis. This is useful for Lissajous patterns.

What is the maximum input voltage for the BNC connectors?

The maximum input voltage is 400 V (DC + peak AC). Do not exceed this rating to avoid damage.

How can I upgrade the firmware?

Download the latest firmware from the Owon website to a USB drive. Insert the drive, go to Utility > Update Firmware, and follow the on-screen instructions. Do not power off during update.

Why is the waveform not stable?

Adjust the Trigger level so it falls within the signal amplitude. Also ensure the trigger source matches the probe channel. For complex signals, try Auto trigger mode.

How do I clean the oscilloscope?

Use a soft, dry cloth to wipe the exterior. For stubborn dirt, slightly dampen the cloth with water. Do not use alcohol or abrasive cleaners.

How to Implement the General Inspection

After you get a new oscilloscope, it is recommended that you should make a check on the instrument according to the following steps:

1. Check whether there is any damage caused by transportation.

If it is found that the packaging carton or the foamed plastic protection cushion has suffered serious damage, do not throw it away first till the complete device and its accessories succeed in the electrical and mechanical property tests.

2. Check the Accessories

The supplied accessories have been already described in the "Appendix A: Enclosure" of this Manual. You can check whether there is any loss of accessories with reference to this description. If it is found that there is any accessory lost or damaged, please get in touch with our distributor responsible for this service or our local offices.

3. Check the Complete Instrument

If it is found that there is damage to the appearance of the instrument, or the instrument can not work normally, or fails in the performance test, please get in touch with our distributor responsible for this business or our local offices. If there is damage to the instrument caused by the transportation, please keep the package. With the transportation department or our distributor responsible for this business informed about it, a repairing or replacement of the instrument will be arranged by us.

How to Implement the Function Inspection

Make a fast function check to verify the normal operation of the instrument, according to the following steps:

1. Connect the power cord to a power source. Long press the button on the bottom left of the instrument.

The instrument carries out all self-check items and shows the Boot Logo. Push the Utility button, select Function in the bottom menu. Select Adjust in the left menu, select Default in the bottom menu. The default attenuation coefficient set value of the probe in the menu is 10X.

1. Set the Switch in the Oscilloscope Probe as 10X and Connect the Oscilloscope with CH1 Channel.

Align the slot in the probe with the plug in the CH1 connector BNC, and then tighten the probe with rotating it to the right side.

Connect the probe tip and the ground clamp to the connector of the probe compensator.

1. Push the Autoset Button on the front panel.

The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in several seconds (see Figure 3-6).

Figure 3-6 Auto set

Check CH2 by repeating Step 2 and Step 3.

How to Implement the Probe Compensation

When connect the probe with any input channel for the first time, make this adjustment to match the probe with the input channel. The probe which is not compensated or presents a compensation deviation will result in the measuring error or mistake. For adjusting the probe compensation, please carry out the following steps:

1. Set the attenuation coefficient of the probe in the menu as 10X and that of the switch in the probe as 10X (see "How to Set the Probe Attenuation Coefficient" on P12), and connect the probe with the CH1 channel. If a probe hook tip is used, ensure that it keeps in close touch with the probe. Connect the probe tip with the signal connector of the probe compensator and connect the reference wire clamp with the ground wire connector of the probe connector, and then push the Autoset button on the front panel.
2. Check the displayed waveforms and regulate the probe till a correct compensation is achieved (see Figure 3-7 and Figure 3-8).

Figure 3-8 Adjust Probe

How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope.

To change or check the probe attenuation coefficient in the menu of oscilloscope:

(1) Push the function menu button of the used channels (CH1 or CH2 button).
(2) Select Probe in the bottom menu; select Attenu in the right menu, turn the M knob to

select the proper value corresponding to the probe.

This setting will be valid all the time before it is changed again.

Caution:

The default attenuation coefficient of the probe on the instrument is p 10X.

Make sure that the set value of the attenuation switch in the probe is same as the menu selection of the probe attenuation coefficient in the oscilloscope.

The set values of the probe switch are 1X and 10X (see Figure 3-9).

Pure technical line drawing of a mechanical component with no text or symbols

Figure 3-9 Attenuation Switch

Caution:

When the attenuation switch is set to 1X, the probe will limit the ba of the oscilloscope in 5MHz. To use the full bandwidth of the oscillo the switch must be set to 10X.

Identify the Probe Attenuation Coefficient Automatically

The oscilloscope can identify the probe attenuation coefficient of the 100:1 (impedance 5K ± 20% ) or 10:1 (impedance 10K ± 20% ) probe with the identifying pin. When you attach the probe, the oscilloscope set the attenuation automatically on the oscilloscope vertical menu for the channel to match the probe.

For example, if you attach a 10:1 probe with the identifying pin, the screen will prompt "The probe attenuation factor is 10X", and set the attenuation to 10X automatically on the oscilloscope vertical menu for the channel.

How to Use the Probe Safely

The safety guard ring around the probe body protects your finger against any electric shock, shown as Figure 3-10.

Line drawing of a soldering iron with a pointed tip and threaded end (no text or symbols)

Figure 3-10 Finger Guard

Warning:

To avoid electric shock, always keep your finger behind the safety gu ring of the probe during the operation.

To protect you from suffering from the electric shock, do not touch a metal part of the probe tip when it is connected to the power supply.

Before making any measurements, always connect the probe to the instrument and connect the ground terminal to the earth.

How to Implement Self-calibration

The self-calibration application can make the oscilloscope reach the optimum condition rapidly to obtain the most accurate measurement value. You can carry out this application program at any time. This program must be executed whenever the change of ambient temperature is 5^ C or over.

Before performing a self-calibration, disconnect all probes or wires from the input connector. Push the Utility button, select Function in the bottom menu, select Adjust. in the left menu, select Self Cal in the bottom menu; run the program after everything is ready.

Introduction to the Vertical System

As shown in Figure 3-11, there are a few of buttons and knobs in Vertical Controls. The following practices will gradually direct you to be familiar with the using of the vertical setting.

Figure 3-11 Vertical Control Zone

1. Use the Vertical Position knob to show the signal in the center of the waveform window. The Vertical Position knob functions the regulating of the vertical display position of the signal. Thus, when the Vertical Position knob is rotated, the pointer of the earth datum point of the channel is directed to move up and down following the waveform.

Measuring Skill

If the channel is under the DC coupling mode, you can rapidly measure the DC component of the signal through the observation of the difference between the wave form and the signal ground.

Using FFT function

The FFT (fast Fourier transform) math function mathematically converts a time-domain waveform into its frequency components. It is very useful for analyzing the input signal on Oscilloscope. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies. FFT function in this oscilloscope transforms 8192 data points of the time-domain signal into its frequency components mathematically (the record length should be 10K or above). The final frequency contains 4096 points ranging from 0Hz to Nyquist frequency. Taking the FFT operation for example, the operation steps are as follows: 1. Press the Math button to display the math menu in the bottom. 2. Select FFT in the bottom menu. 3. In the right menu, select Source as CH1. 4. In the right menu, select Window. In the left menu, turn the M knob to select the proper window type. 5. In the right menu, select Format. In the left menu, turn the M knob to select amplitude unit (V RMS, Decibels) or phase unit (Radian, Degrees). 6. Select Hori (Hz) in the right menu; select repeatedly to make the symbol in front of the horizontal position value (the upper one), turn the M knob to adjust the horizontal position of FFT waveform; then select to make the symbol in front of the time base value below, turn the M knob to adjust the time base of FFT waveform. 7. Select Vertical in the right menu; do the same operations as above to set the vertical position and vertical division.

To select the FFT window

■ There are 6 FFT windows. Each one has trade-offs between frequency resolution and magnitude accuracy. What you want to measure and your source signal characteristics help you to determine which window to use. Use the following guidelines to select the best window.

Type	Characteristics	Window
Hamming	Better solution for magnitude than Rectangle, an good for frequency as well. It has slightly better frequency resolution than Hanning.Recommend to use for:Sine, periodic and narrow band random noisTransients or bursts where the signal levels before and after the event are significantly different.
Rectangle	Best solution for frequency, worst for magnitudeBest type for measuring the frequency spectrum nonrepetitive signals and measuring frequency components near DC.Recommend to use for:Transients or bursts, the signal level before a after the event are nearly equal.Equal-amplitude sine waves with frequencies those are very close.Broadband random noise with a relatively sl varying spectrum.
Blackman	Best solution for magnitude, worst for frequencyRecommend to use for:Single frequency waveforms, to find higher order harmonics.
Hanning	Good for magnitude, but poorer frequency resolution than Hamming.Recommend to use for:Sine, periodic and narrow band random noisTransients or bursts where the signal levels before and after the event are significantly different.
Kaiser	The frequency resolution when using the Kaiser window is fair; the spectral leakage and amplitude accuracy are both good.The Kaiser window is best used when frequencie are very close to the same value but have widely differing amplitudes (the side lobe level and sha factor are closest to the traditional Gaussian RB This window is also good for random signals.
Bartlett	The Bartlett window is a slightly narrower varia of the triangular window, with zero weight at bends.

Figure 4-1, Figure 4-2, Figure 4-3, Figure 4-4, Figure 4-5, Figure 4-6 are examples for measuring sine wave with a frequency of 1kHz under the selection of six different windows for FFT:  Figure 4-1 Hamming window  Figure 4-2 Rectangle window  Figure 4-3 Blackman window  Figure 4-4 Hanning window  Figure 4-5 Kaiser window  Figure 4-6 Bartlett window

Notes for using FFT

■ Use the default dB scale for details of multiple frequencies, even if they have very different amplitudes. Use the dB scale to compare frequencies. ■ DC component or offset can cause incorrect magnitude values of FFT waveform. To minimize the DC component, choose AC Coupling on the source signal. ■ To reduce random noise and aliased components in repetitive or single-shot events, set the oscilloscope acquisition mode to average.

What is Nyquist frequency?

The Nyquist frequency is the highest frequency that any real-time digitizing oscilloscope can acquire without aliasing. This frequency is half of the sample rate. Frequencies above the Nyquist frequency will be under sampled, which causes aliasing. So pay more attention to the relation between the frequency being sampled and measured.

Use Vertical Position and Scale Knobs

1. The Vertical Position knob is used to adjust the vertical positions of the waveforms. The analytic resolution of this control knob changes with the vertical division. 2. The Vertical Scale knob is used to regulate the vertical resolution of the wave forms. The sensitivity of the vertical division steps as 1-2-5. The vertical position and vertical resolution is displayed at the left bottom corner of the screen (see Figure 4-7).  Figure 4-7 Information about Vertical Position

How to Set the Horizontal System

The HORIZONTAL CONTROLS includes the Horizontal HOR button and such knobs as Horizontal Position and Horizontal Scale. 1. Horizontal Position knob: this knob is used to adjust the horizontal positions of all channels (include those obtained from the mathematical manipulation), the analytic resolution of which changes with the time base. 2. Horizontal Scale knob: it is used to set the horizontal scale factor for setting the main time base or the window. 3. Horizontal HOR button: push it to switch between the normal mode and the wave zoom mode. For more detailed operations, see the introductions below.

In wave zoom mode, the Horizontal Position and Horizontal Scale knobs are used to adjust the horizontal position and time base of the Zoom window.

Note:

About the gestures for touchscreen, see "Touchscreen Controls (Touchscreen is optional)" on P17.

How to Set the Trigger/Decoding System

Trigger determines when DSO starts to acquire data and display waveform. Once trigger is set correctly, it can convert the unstable display to meaningful waveform. When DSO starts to acquire data, it will collect enough data to draw waveform on left of trigger point. DSO continues to acquire data while waiting for trigger condition to occur. Once it detects a trigger it will acquire enough data continuously to draw the waveform on right of trigger point. Trigger control area consists of 1 knob and 2 menu buttons. Trigger Level: The knob that set the trigger level; push the knob and the level will be set as the vertical mid point values of the amplitude of the trigger signal. Force: Force to create a trigger signal and the function is mainly used in "Normal" and "Single" mode. Trigger Menu: The button that activates the trigger control menu.

9. Demonstration

Example 1: Measurement a Simple Signal

The purpose of this example is to display an unknown signal in the circuit, and measure the frequency and peak-to-peak voltage of the signal. 1. Carry out the following operation steps for the rapid display of this signal: (1) Set the probe menu attenuation coefficient as 10X and that of the switch in the probe switch as 10X (see "How to Set the Probe Attenuation Coefficient" on P12). (2) Connect the probe of Channel 1 to the measured point of the circuit. (3) Push the Autoset button. The oscilloscope will implement the Autoset to make the waveform optimized, based on which, you can further regulate the vertical and horizontal divisions till the waveform meets your requirement.

2. Perform Automatic Measurement

To measure the period, the frequency of the CH1, following the steps below: (1) Push the Measure button to show the Measure menu. (2) Select Add in the bottom menu. (3) In the right menu, select CH1 in the Source menu item. (4) In the left Type menu, turn the M knob to select Period. (5) In the right menu, select Add. The period type is added. (6) In the left Type menu, turn the M knob to select Frequency. (7) In the right menu, select Add. The frequency type is added. The measured value will be displayed at the bottom left of the screen automatically (see Figure 9-1).  Figure 9-1 Measure period and frequency value for a given signal

Example 2: Gain of a Amplifier in a Metering Circuit

The purpose of this example is to work out the Gain of an Amplifier in a Metering Circuit. First we use Oscilloscope to measure the amplitude of input signal and output signal from the circuit, then to work out the Gain by using given formulas. Set the probe menu attenuation coefficient as 10X and that of the switch in the probe as 10X (see "How to Set the Probe Attenuation Coefficient" on P12). Connect the oscilloscope CH1 channel with the circuit signal input end and the CH2 channel to the output end.

Operation Steps:

(1) Push the Autoset button and the oscilloscope will automatically adjust the waveforms of the two channels into the proper display state. (2) Push the Measure button to show the Measure menu. (3) Select Add in the bottom menu. (4) In the right menu, select CH1 in the Source menu item. (5) In the left Type menu, turn the M knob to select PK-PK. (6) In the right menu, select Add. The peak-to-peak type of CH1 is added. (7) In the right menu, select CH2 in the Source menu item. (8) In the left Type menu, turn the M knob to select PK-PK. (9) In the right menu, select Add. The peak-to-peak type of CH2 is added. (10)Read the peak-to-peak voltages of Channel 1 and Channel 2 from the bottom left of the screen (see Figure 9-2). (11)Calculate the amplifier gain with the following formulas. Gain = Output Signal / Input signal Gain (db) = 20×log (gain)  Figure 9-2 Waveform of Gain Measurement

Example 3: Capturing a Single Signal

It's quite easy to use Digital Oscilloscope to capture non-periodic signal, such as a pulse and burr etc. But the common problem is how to set up a trigger if you have no knowledge of the signal? For example, if the pulse is the logic signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge trigger. With various functions supported by our Oscilloscope, user can solve this problem by taking an easy approach. First to run your test using auto trigger to find out the closest trigger level and trigger type, this helps user to make few small adjustments to achieve a proper trigger level and mode. Here is how we achieve this.

The operation steps are as follows:

(1) Set the probe menu attenuation coefficient to 10X and that of the switch in the probe to 10X (see "How to Set the Probe Attenuation Coefficient" on P12). (2) Adjust the Vertical Scale and Horizontal Scale knobs to set up a proper vertical and horizontal ranges for the signal to be observed. (3) Push the Acquire button to display the Acquire menu. (4) Select Acqu Mode in the bottom menu. Select Peak Detect in the right menu. (5) Push the Trigger Menu button to display the Trigger menu. (6) Select the first menu item in the bottom menu. Select Single in the right menu. (7) In the left menu, select Edge as the mode. (8) Select Source in the bottom menu. Select CH1 in the right menu. (9) Select Coupling in the bottom menu. Select DC in the right menu. (10)In the bottom menu, select Slope as (rising). (11)Turn the Trigger Level knob and adjust the trigger level to the roughly 50% of the signal to be measured. (12)Check the Trigger State Indicator on the top of the screen, if it is not Ready, push down the Run/Stop button and start acquiring, wait for trigger to happen. If a signal reaches to the set trigger level, one sampling will be made and then displayed in the screen. By using this approach, a random pulse can be captured easily. For instance, if we want to find a burst burr of high amplitude, set the trigger level to a slightly higher value of the average signal level, push the Run/Stop button and wait a trigger. Once there is a burr occurring, the instrument will trigger automatically and record the waveform during the period around the trigger time. By turning the Horizontal Position knob in the horizontal control area in the panel, you can change the horizontal triggering position to obtain the negative delay, making an easy observation of the waveform before the burr occurs (see Figure 9-3).  Figure 9-3 Capturing a Single Signal

Example 4: Analyze the Details of a Signal

Noise is very common inside most of the electronic signal. To find out what's inside the noise and reduce the level of noise is very important function our oscilloscope is capable to offer. Noise Analysis The level of noise sometime indicates a failure of electronic circuit. The Peak Detect functions acts an important role to help you to find out the details of these noise. Here is how we do it: (1) Push the Acquire button to display the Acquire menu. (2) Select Acqu Mode in the bottom menu. (3) Select Peak Detect in the right menu. The signal displayed on the screen containing some noise, by turning on Peak Detect function and changing time base to slow down the incoming signal, any peaks or burr would be detected by the function (see Figure 9-4).  Figure 9-4 Signal with Noises

Separate Noises from the Signal

When focusing on signal itself, the important thing is to reduce the noise level as lower as possible, this would enable user to have more details about the signal. The Average function offered by our Oscilloscope can help you to achieve this. Here are the steps for how to enable Average function. (1) Push the Acquire button to display the Acquire menu. (2) Select Acqu Mode in the bottom menu. (3) Select Average in the right menu, turn the M knob and observe the waveform obtained from averaging the waveforms of different average number. User would see a much reduced random noise level and make it easy to see more details of the signal itself. After applying Average, user can easily identify the burrs on the rising and falling edges of some part of the signal (see Figure 9-5).  Figure 9-5 Reduce Noise level by using Average function

Example 5: Application of X-Y Function

Examine the Phase Difference between Signals of two Channels

Example: Test the phase change of the signal after it passes through a circuit network. X-Y mode is a very useful when examining the Phase shift of two related signals. This example takes you step by step to check out the phase change of the signal after it passes a specified circuit. Input signal to the circuit and output signal from circuit are used as source signals. For the examination of the input and output of the circuit in the form of X-Y coordinate graph, please operate according to the following steps: (1) Set the probe menu attenuation coefficient for 10X and that of the switch in the probe for 10X (see "How to Set the Probe Attenuation Coefficient" on P12). (2) Connect the probe of channel 1 to the input of the network and that of Channel 2 to the output of the network. (3) Push the Autoset button, with the oscilloscope turning on the signals of the two channels and displaying them in the screen. (4) Turn the Vertical Scale knob, making the amplitudes of two signals equal in the rough. (5) Push the Display button and recall the Display menu. (6) Select XY Mode in the bottom menu. Select Enable as ON in the right menu. The oscilloscope will display the input and terminal characteristics of the network in the Lissajous graph form. (7) Turn the Vertical Scale and Vertical Position knobs, optimizing the waveform. (8) With the elliptical oscillogram method adopted, observe and calculate the phase difference (see Figure 9-6).  Figure 9-6 Lissajous Graph Based on the expression (q) = A / B or C / D , thereinto, q is the phase difference angle, and the definitions of A, B, C, and D are shown as the graph above. As a result, the phase difference angle can be obtained, namely, q = ± (A / B) or ± (C / D) . If the principal axis of the ellipse is in the I and III quadrants, the determined phase difference angel should be in the I and IV quadrants, that is, in the range of (0 - / 2) or (3 / 2 - 2) . If the principal axis of the ellipse is in the II and IV quadrants, the determined phase difference angle is in the II and III quadrants, that is, within the range of ( / 2 - ) or ( - 3 / 2) .

Example 6: Video Signal Trigger

Observe the video circuit of a television, apply the video trigger and obtain the stable video output signal display.

Video Field Trigger

(2) Select the first menu item in the bottom menu. Select Single in the right menu. (3) In the left menu, select Video as the mode. (4) Select Source in the bottom menu. Select CH1 in the right menu. (5) Select Modu in the bottom menu. Select NTSC in the right menu. (6) Select Sync in the bottom menu. Select Field in the right menu. (7) Turn the Vertical Scale, Vertical Position and Horizontal Scale knobs to obtain a proper waveform display (see Figure 9-7).  Figure 9-7 Waveform Captured from Video Field Trigger

10. Troubleshooting

1. Oscilloscope is powered on but no Display. - Check whether the power connection is connected properly. - Check whether the fuse which is beside the AC power input jack is blew (the cover can be pried open with a straight screwdriver). - Restart the instrument after completing the checks above. - If the problem persists, please contact us and we will be under your service. 2. After acquiring the signal, the waveform of the signal is not displayed in the screen. - Check whether the probe is properly connected to the signal connecting wire. - Check whether the signal connecting wire is correctly connected to the BNC (namely, the channel connector). - Check whether the probe is properly connected with the object to be measured. - Check whether there is any signal generated from the object to be measured (the trouble can be shot by the connection of the channel from which there is a signal generated with the channel in fault). ● Make the signal acquisition operation again. 3. The measured voltage amplitude value is 10 times or 1/10 of the actual value. Look at the attenuation coefficient for the input channel and the attenuation ration of the probe, to make sure they are match (see "How to Set the Probe Attenuation Coefficient" on P12). 4. There is a waveform displayed, but it is not stable. - Check whether the Source item in the TRIG MODE menu is in conformity with the signal channel used in the practical application. - Check on the trigger Type item: The common signal chooses the Edge trigger mode for Type and the video signal the Video. If Alternate trigger is selected, both of the channel 1 and channel 2 trigger levels should be adjusted to the proper position. Only if a proper trigger mode is applied, the waveform can be displayed steadily. - Try to change the trigger coupling into the high frequency suppress and the low frequency suppress to smooth the high frequency or low frequency noise triggered by the interference. (Only for the models that have this function.) 5. No Display Responses to the Push-down of Run/Stop. Check whether Normal or Single is chosen for Polarity in the TRIG MODE menu and the trigger level exceeds the waveform range. If it is, make the trigger level is centered in the screen or set the trigger mode as Auto. In addition, with the Autoset button pressed, the setting above can be completed automatically. 6. The displaying of waveform seems getting slow after increasing AVERAGE value in Acqu Mode (see "How to Implement Sampling Setup" on P60), or a longer duration is set in the Persist in Display (see "Persist" on P63). It's normal as the Oscilloscope is working hard on many more data points.
