Burst Mode Commands
BURSt:MODE {TRIGgered|GATed}
BURSt:MODE?
Select the burst mode. In the triggered mode, the function generator
outputs a waveform with a specified number of cycles (burst count) each
time a trigger is received from the specified trigger source (TRIG:SOUR
command). In the gated mode, the output waveform is either “on” or “off ”
based on the level of the external signal applied to the rear-panel
Trig In connector. The default is TRIG. The :MODE? query returns
“TRIG” or “GAT”.
•When the gated mode is selected, the waveform generator either runs
or stops based on the logic level of the gate signal applied to the rear-
panel Trig In connector. You can select the polarity of the Trig In
connector using the BURS:GATE:POL command (see page 194).
When the gate signal is true, the function generator outputs a
continuous waveform. When the gate signal goes false, the current
waveform cycle is completed and then the function generator stops
while remaining at the voltage level corresponding to the starting
burst phase of the selected waveform. For a noise waveform, the
output stops immediately when the gate signal goes false.
•When the gated mode is selected, the burst count, burst period,
and trigger source are ignored (these parameters are used for the
triggered burst mode only). If a manual trigger is received (TRIG
command), it is ignored and no error will be generated.
Use the APPLy command or the equivalent FUNC, FREQ, VOLT, and
VOLT:OFFS commands to configure the waveform. For internally-
triggered bursts, the minimum frequency is 2 mHz. For sine and square
waveforms, frequencies above 25 MHz are allowed only with an
“infinite” burst count.
