Glossary

Pulse Width

PW is an abbreviation for pulse width and is divided into positive pulse width negative pulse width.

The positive pulse width is the time interval from 50% of the rising edge to 5 the adjacent falling edge.

The negative pulse width is the time interval from 50% of the falling edge to the adjacent rising edge.

The pulse width is determined by the period and duty cycle of the signal. The calculation formula is pulse width = period * duty cycle.

Duty Cycle

In a series of ideal pulse sequences (such as a square wave), the ratio of the of the positive pulse to the total pulse period.

Pulse/Duty Cycle

The pulse width is defined as the time interval from the 50% threshold of the amplitude of the rising edge of the pulse to the 50% threshold of the amplitude the next falling edge, as shown in the following figure.

• The settable range of pulse width is limited by the "minimum pulse width" "pulse period"
  Pulse width ≥ minimum pulse width
  Pulse width ≤ pulse period - minimum pulse width
• The pulse duty cycle is defined as the pulse width as a percentage of the period.
• The pulse duty cycle is associated with the pulse width, and modifying one parameters will automatically modify the other parameter. The pulse duty cycle is limited by the "minimum pulse width" and "pulse period".
  Pulse duty cycle ≥ minimum pulse width ÷ pulse period × 100%
  Pulse duty cycle ≤ (1 - 2 × minimum pulse width ÷ pulse period) × 100%

Output Harmonic Wave

Press the Harmonic wave button, the screen displays the user interface of the harmonic wave. The Harmonic waveform parameters can be set by operating the Harmonic setting menu on the right.

The harmonic wave menu includes: Frequency/Period, Amplitude/High Level, Offset/Low Level, Start Phase, Harmonic Type, Harmonic Order, Sequence Number, Harmonic Amplitude, Harmonic Phase.

Figure 5-10: Harmonic wave user interface

Harmonic wave function overview

According to Fourier transform theory, time domain waveform is the superposition of a series of sine waveforms, expressed by the following equation:

$$ f (t) = A _ {1} \sin \left(2 \pi f _ {1} t + \varphi_ {1}\right) + A _ {2} \sin \left(2 \pi f _ {2} t + \varphi_ {2}\right) + A _ {3} \sin \left(2 \pi f _ {3} t + \varphi_ {3}\right) + \dots $$

Generally, the component of frequency f_1 is called the fundamental wave f_1 is the fundamental waveform frequency A_1 is the fundamental waveform amplitude, and _1 is the fundamental waveform phase. The frequencies of other component are all integral multiples of the fundamental waveform frequency, which is called harmonic. A component whose frequency is an odd multiple of the fundamental frequency is called an odd harmonic, and a component whose frequency is an even multiple of the fundamental frequency is called an even harmonic.

This waveform generator can output up to 16th order of harmonic. After selecting CH1 or CH2, press the Harmonic wave button to enter the harmonic setting menu. You can set the parameters of the fundamental waveform, select the type of harmonic, specify the highest order of harmonic, and set the amplitude and phase of each order of harmonic.

You only need to use the numeric keypad to modify the value of each data bit (Note: the leftmost bit reresents the fundamental wave, which is fixed to X and cannot be modified). For example, set the 16-bit data to X001 0000 0000 0001, the generator will output the fundamental wave, the 4th order harmonic, and the 16th order harmonic.

Glossary

Burst:

The set of pulses transmitted together is called a "burst". The various signal generators are commonly referred to as the BURST function.

N cycle burst:

Contains a specific number of waveform cycles, each of which is initiated by a event.

Gated burst:

Use external department signals to control when waveform burst waveforms are active.

Set N-Cycle Burst

When Infinite is selected, the cycle number of the waveform is set as an infinite value. The generator outputs a continuous waveform after receiving trigger signal.

Note: In burst mode, the upper limit of the carrier frequency is half of the max frequency of the original carrier. Taking a Sine wave as an example, the maximum frequency is 100 MHz. Press\~, and set the carrier to 100 MHz, then press the Burst mode key, then press\~, you can see the carrier frequency is changed to 50 MHz.

Note:

• If needed, Burst Period will increase to cater to the specific number of cycles.
• For an infinite-cycle Burst, External or Manual Trigger is needed to activate burst.

(5) Burst trigger source could be internal, external or manual. The generator will generate a burst output when a trigger signal is received and then wait for the next trigger. Press the Trigger to select the source.

Internal means using the internal trigger source. The generator can only output N-cycle burst and the burst frequency is determined by the burst period. Burst period is only available when Cycles and Internal trigger is highlighted. Press the Bust Period softkey to set the burst period, which is the time from the start of a burst to the start of the next burst. The range is from 20 ns to 500 s (Min = Cycles * Period).

External means using the Mod/FSK/Trig connector at the rear panel to input the external trigger signal. A burst will be generated once the connector gets a TTL pulse with specified polarity. To set the TTL pulse polarity, press the Slope softkey to switch between Positive and Negative.

Manual means using manual trigger. In N-cycle burst interface, each time you press the Trigger button under the current channel on the front panel, a burst will be generated.

Set Gated Burst

In gated burst mode, the generator controls the waveform output according to the external signal level from the Mod/FSK/Trig connector at the rear panel. Gated burst could only be triggered by external trigger source. Waveform functions which support gated burst are Sine, Square, Ramp, Pulse, Noise and Arbitrary waveforms (except DC).

CH1/2 Settings

Sync

The generator can output the sync signals of basic waveforms (except noise), arbitrary waveforms (except DC), harmonics, sweep signal, burst signal, and modulated signal from a single channel or two channels at the same time. This sync signal is output from the Sync connector at the front panel.

The steps to enable or disable sync signal at the Sync connector:

(2) Press the CH1 Sync or CH2 Sync softkey, press it again to toggle between On and Off. The default is "On", which sends the sync signal to the Sync connector.

When the sync signal is disabled, the output level at the Sync connector is logic low.

Sync signals of various waveforms

• For sine, square, ramp and pulse waves, the sync signal is a square wave with a 50% duty cycle. When the waveform output is positive, the sync signal is TTL high with respect to the 0V voltage (or DC offset value). When the waveform output is negative, the sync signal is TTL low relative to the 0V voltage (or DC offset value).
• For arbitrary waveform, the sync signal is a square wave with a variable duty cycle. When the output waveform amplitude reaches a certain value, the sync signal is TTL high.
• For harmonics, the sync signal is referenced to the harmonic order and is a square wave with a variable duty cycle. When the output waveform amplitude is positive, the sync signal is TTL high.
• For AM, FM, PM, and PWM, for internal modulation, the sync signal is referenced to the modulation frequency, and the sync signal is a square wave with a 50% duty cycle. In the first half of the modulation waveform, the sync signal is TTL high. When external modulation is performed, there is no sync signal output.

• For ASK, FSK, PSK, BPSK, QPSK, 3FSK, 4FSK, the synchronization signal is referenced to the keying frequency, and the synchronization signal is a square wave with a duty cycle of 50% . There is no sync signal output during external modulation.

• For OSK, the sync signal is referenced to the keyed frequency and the sync signal is a square wave with a 50% duty cycle. When the internal crystal oscillator starts, the sync signal is TTL high.

• For N-cycle bursts, the sync signal is TTL high at the beginning of the burst. At the end of the specified number of cycles, the sync signal is TTL low (if the waveform has an associated start phase, it may not be a zero crossing). For an infinite count pulse train, the sync signal is the same as the sync signal of the continuous waveform.
• For external gated bursts, the sync signal follows its gate signal. Note: This signal does not become TTL low until the end of the last cycle (if the waveform has an associated starting phase, it may not be a zero crossing).

Load

For either of Out1 and Out2 connector at the front panel, the generator has a 50Ω fixed serial output impedance. If the actual load does not match the specified value, the voltage level displayed would not match the voltage level of the component under test. This function is used to match the displayed voltage with the expected one.

6. Communicate with PC

Supports communication with a computer via a USB port or a LAN port. Using the Waveform Editor software installed on the computer, the signal generator can be operated on the computer to control the output of the signal generator.

Here's how to connect to a computer. First, install the Waveform Editor software on the CD-ROM on your computer. Then, there are several connection options to choose from.

Using USB Port

(1) Set the USB device protocol type of the signal generator: Press Utility → I/O Setup → USBDEV, switch to PC.
(2) Connection: Connect the USB Device interface at the rear panel of the signal generator to the USB interface of the computer with a USB cable.
(3) Install the driver: Run Waveform Editor software on the computer. Follow the instructions to install the driver. The path of the driver is the USBDRV folder in the directory where the Waveform Editor communication software is located, such as "C:\Program Files (x86)\DS_Wave\Waveform Editor\USBDRV".
(4) Host computer communication port setting: Open the Waveform Editor software, click "Communications" in the menu bar, select "Ports-Settings", in the setting dialog box, select the communication port as "USB". After the connection is successful, the connection status prompt in the lower right corner of the software interface turns green.

Using LAN Port

Connect Directly

(1) Connection. Plug one end of the network cable into the LAN connector on the rear panel of the signal generator; the other end is plugged into the LAN interface of the computer.
(2) Set the network parameters of the computer. Since the signal generator does not support automatic IP address acquisition, you need to specify the IP yourself. Here we set the IP address to 192.168.1.71.
(3) Set the network parameters of the host computer. Run Waveform Editor software on the computer. In the "Communications" menu, under "Ports-Settings", select the communication port as "LAN", the IP is set to be the same as the first three fields of the computer's network IP in step (2), and the last field has a different IP address. It is "192.168.1.99"; the port can be set to any value from 0 to 4000. However, since ports below 2000 are often occupied,

it is recommended to set it to 2000 or higher. Here, it is set to "3000".

Figure 6-1: Setting the network parameters of the host computer

(4) Set the network parameters of the signal generator. In the signal generator, press Utility → I/O Setup → Network setting to enter the submenu. Set the IP address and port to the IP and port in the PC software port settings in step (3). After the shutdown and restart, if the data can be obtained normally in the PC software, the connection is successful.

Connect through a Router

(1) Connection. Connect the LAN interface on the rear panel of the signal generator to the router with a network cable. The computer is also connected to the router.
(2) Set the network parameters of the computer. Since the signal generator does not support automatic IP address acquisition, you need to specify the IP yourself. The default gateway and subnet mask settings must match the settings of the router. For example, the IP address is set to 192.168.1.71, the subnet mask is set to 255.255.255.0, and the default gateway is set to 192.168.1.1.
(3) Set the network parameters of the host computer. Run Waveform Editor software on the computer. In the "Communications" menu, under "Ports-Settings", select the communication port as "LAN", the IP is set to be the same as the first three fields of the computer's network IP in step (2), and the last field has a different IP address. It is "192.168.1.99"; the port can be set to any value from 0 to 4000. However, since ports below 2000 are often occupied, it is recommended to set it to 2000 or higher. Here, it is set to "3000".

Figure 6-2: Set the network parameters of the host computer

(4) Set the network parameters of the signal generator. In the signal generator,

press Utility → I/O Setup → Network setting to enter the submenu. Set the IP address and port to the IP and port in the PC software port settings in step (3). The gateway settings need to be the same as the gateway settings of the router. After the shutdown and restart, if the data can be obtained normally in the PC software, the connection is successful.

7. Troubleshooting

1. The screen is still black and there is no display after you press the power switch, please follow the steps below:

2. Check whether the power is connected correctly.

3. Check whether the fuse below the power connector meets the specified type and rating and in good condition (the cover can be pried open with a flat-blade screwdriver).
4. Restart the instrument after completing the above inspections.

5. If the problem still exists, please contact us for our service.

6. The measured value of the output signal amplitude does not match the displayed value:

Check whether the actual load value of the signal is consistent with the load value set in the instrument. Please refer to Load on page 55.

If you encounter other problems, please try to reset the settings (see Restore to the factory setting on page 61) or restart the instrument. If it still can not work properly, please contact us for our service.

8. Specification

All technical specifications are guaranteed when the following conditions are met, unless otherwise stated.

• The signal generator must be operated continuously for more than 30 minutes at the specified operating temperature (20°C to 30°C) to meet these specifications;
• The signal generator is in the calibration internal and has performed a self-calibration.

In addition to the specifications marked with the word "Typical", the specifications used are guaranteed.
