SOURce[1–8]:FUNCtion:SHAPe TBURst
Usage: This command generates a sine-wave burst with variable amplitude, frequency,
and on and off times. The burst always begins and ends at the positive
sine-wave zero crossing. The generator converts the width-time parameter into
the nearest number of cycles of sine wave to generate.
Range: Frequency 10 Hz to 80,000 Hz
Amplitude 0.0625 V to 19.45 V
Burst Period 64/(sample rate) to 36,000 sec
Burst Width 32/(sample rate) to 18,000 sec
Units: Frequency Hz
Amplitude Volts RMS
Burst Period Seconds
Burst Width Seconds
Resolution: Frequency 0.1 Hz
Voltage 1 mV
Burst Period 32/(sample rate) sec
Burst Width 32/(sample rate) sec
Default: 64 cycles on, 64 cycles off.

The amplitude of the tone burst is controllable using the AMPLITUDE knob of the
generator. The frequency of the tone burst is controllable using the FREQUENCY
knob of the generator. The parameters of the tone burst signal may be entered
separately to effect changes to the test signal.
