Figure 4- 132 Observe frequency sweep waveform with oscilloscope 

4.3 Output Burst 

Signal generator can create a waveform with designated recurring number (known as pulse train). The function/arbitrary 

waveform generator  supports control of pulse train output with internal, external or manual trigger, and three types of 

pulse train, including N cycle, gating and infinite. It can generate pulse train for sine wave, square wave, sawtooth wave, 

pulse wave, arbitrary wave (except DC) and noise (only applicable to gating pulse train). The modulation mode of the two 

channels is mutually independent. You can configure identical or different modulation mode for channels 1 and 2. 

4.3.1 

Select Burst 

Start Burst function 

Press  BURST to start function of pulser. After pulse train function is used, the function/arbitrary waveform generator will 

output pulse train with the current setting.
