Burst Mode Commands
4
1 Configure the burst waveform.
Use the APPLy command or the equivalent FUNC, FREQ, VOLT, and
VOLT:OFFS commands to select the function, frequency, amplitude,
and offset of the waveform. You can select a sine, square, or ramp
waveform (pulse, noise, dc, and arbitrary are not allowed). For
internally-triggered bursts, the minimum frequency is 2.001 mHz. For
sine and square waveforms, frequencies above 3 MHz are allowed only
with an “infinite” burst count.
2 Select the “triggered” or gated burst mode.
Select the triggered burst mode (called “N Cycle” on the front panel) or
external gated burst mode using the BURS:MODE command.
3 Set the burst count.
Set the burst count (the number of cycles per burst) to any value between
1 and 50,000 cycles (or infinite) using the BURS:NCYC command. Used in
the triggered burst mode only.
4 Set the burst period.
Set the burst period (the interval at which internally-triggered bursts
are generated) to any value from 1 µs to 500 seconds using the
BURS:INT:PER command. Used only in the triggered burst mode with an
internal trigger source.
5 Set the burst starting phase.
Set the starting phase of the burst to any value from -360 degrees to
+360 degrees using the BURS:PHAS command.
6 Select the trigger source.
Select the trigger source using the TRIG:SOUR command. Used in the
triggered burst mode only.
7 Enable the burst mode.
After you have set up the other burst parameters, use the
BURS:STAT ON
command to enable the burst mode.
