pulse_trig
This command selects the trigger mode (continuous, burst, or trigger burst) and initiates the start of pulse output
or arms the pulse card.
Usage
int pulse_trig(int
instr_id
, long
mode
);
instr_id
The instrument identification code of the pulse card, such as VPU1 or VPU2
mode
Trigger mode:
•
Burst:
0
•
Continuous:
1
•
Trigger burst:
2
Pulse modes
Standard, Full Arb, Segment Arb
Details
With the software trigger source selected, this command sets the trigger mode (continuous, burst, or
trig burst) for both pulse card channels, and initiates the start of pulse output.
A burst is a finite number of pulses (1 to 2
32
-1). The only difference between burst and trig burst is the
behavior of trigger output. When using the burst or trig burst trigger mode, make sure to first set the
pulse count before starting pulse output. The
pulse_burst_count
command is used to set the
burst count.
See
(on page 5-66) for details on triggering.
If pulse delay is set to zero (0), pulse output will start immediately after it is triggered. If pulse delay is
more than 0, pulse output will start after the delay period expires
This setting affects both output channels.
Example
pulse_trig(VPU1, 0)
Initiates (triggers) burst pulse output.
