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 Implement the Probe

Compensation" on P14), 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, see Figure 3-5. Regulate the probe till a correct compensation is achieved, see Figure 3-6.

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

(1) Click the channel information display bar on the bottom left of the screen (CH1 Channel, CH2 Channel, CH3 Channel or CH4 Channel).
(2) Select Probe Attenu (1X,10X or other custom probe magnifications) in the displayed channel setting window. The setting will remain in effect until changed again after selection.

Caution:

The default attenuation coefficient of the probe on the instrum preset to 10X.

Make sure that the set value of the attenuation switch in the is the 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 3-7.

When turning the Vertical Position knob, the pointer indicating the

Grounding Reference Point of the channel moves up and down following the waveform. When pressing the Vertical Vertical key, the vertical position can be zero.

Measuring Skills

If the DC coupling mode is adopted for the channel, observe the gap between the waveform and the signal ground to quickly measure the DC component of the signal.

If the AC coupling mode is adopted for the channel, the DC component of the signal is filtered out, facilitating you to display the AC component of the signal with higher sensitivity.

If the Ground coupling mode is adopted for the channel, indicates that the internal input is grounded and the external input is disconnected. It can effectively reduce the influence of external interference on the measurement results and ensure the accuracy of the measurement.

1. Change the vertical settings and observe the resulting status change.

You can determine the change of the vertical scale factor of any channel through the information displayed in the information display bar at the lower part of the waveform window.

How To Set FFT

FFT decomposes the signal into component frequencies, and the oscilloscope uses these component frequencies to display the graph of signal frequency domain, which corresponds to the standard time domain graph of the oscilloscope. Then match these frequencies with known system frequencies, such as the system clock, oscilloscope or power supply. The FFT operation of this instrument can convert 8192 data points of the time domain waveform into frequency domain signal (the recording length of the acquisition shall be set to 512K points or above). And the final FFT spectrum contains 4096 points from DC (0Hz) to Nyquist frequency. The FFT setting window is shown as follows:  FFT operating steps are as follows: 1. Click in the right corner of screen, then select FFT, the screen will pop up FFT setting window. 2. Click Switch when the switch label is highlighted on the right, it is enabled. The pink waveform M will be displayed on the screen (It is also available to click FFT shortcut softkey at the upper part of the screen). 3. Click the signal source CH1. 4.

Note:12-14 valid only when peak display is on. The Description of FFT Window There are 6 FFT windows. Each one has trade-offs between frequency resolution and amplitude 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	Descriptions	Window
Rectangle	Best solution for frequency, worst for amplitudeBest 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 and after the event are nearly equal.Equal-amplitude sine waves with frequencies those are very close.Broadband random noise with a relatively slow varying spectrum.
Hanning	Good for amplitude, but poorer frequency resolution than Hamming.Recommend to use for:Sine, periodic and narrow band random noiseTransients or bursts where the signal levels before and after the event are significantly different.
Hamming	Better solution for amplitude than Rectangle, argood for frequency as well. It has slightly better frequency resolution than Hanning.Recommend to use for:Sine, periodic and narrow band random noiseTransients or bursts where the signal levels before and after the event are significantly different.
Blackman	Best solution for amplitude, worst for frequencyRecommend to use for:Single frequency waveforms, to find higher order harmonics.
Bartlett	The Bartlett window is a slightly narrower varia of the triangular window, with zero weight at both ends.
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 frequenciesare very close to the same value but have wide differing amplitudes (the side lobe level and sh factor are closest to the traditional Gaussian RBW). This window is also good for random signals.

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.
