Specify the burst mode. The default is Triggered mode. In the triggered mode,
the waveform generator outputs a waveform with specified number of cycles
(burst count) each time a trigger is received from the specified trigger source. In
the gated mode, the output waveform is either “on” or “off” based on the
external signal level on the Ext Trig connector on the rear panel.
--Use BURS:GATE:POL command to specify the polarity of
Ext Trig
connector on
the rear panel.
--When the gate signal is true, the waveform generator outputs a continuous
waveform. When the gate signal is false, the current waveform is complete and
the waveform generator stops while remaining at the voltage level
corresponding to the starting burst phase of the selected waveform. And the
output stops immediately in a noise waveform when the gate signal is false
.
--
The burst count, burst period and trigger source are for triggered burst mode
only.
BURSt:MODE?
“TRIG” or “GAT” will be returned.
BURSt:NCYCles {<# cycles>|INFinity|MINimum|MAXimum}
Specify the number of cycles to be output in each burst (triggered burst mode
only). The range is from 1 to 50,000 cycles in 1 cycle increments and the default
is 1 cycle. The maximum value depends on the burst period and frequency as
shown below. Specify Infinite to generate a continuous burst waveform When
using the Immediate(Internal) trigger source
(TRIG:SOUR IMM command),
the
burst count must be less than the product of the maximum burst period and the
waveform frequency:
Burst Count < Maximum period x Frequency.
--
The waveform generator will automatically increase the burst period up to its
maximum value to accommodate the specified burst count, but it won’t change
the waveform frequency.
-- The burst count does not apply in the gated mode. However, if you specify a
new burst count while in the gated mode, the waveform generator will
remember it and use it when the triggered mode is selected.
