pgu_trig_burst
This command triggers a specified number of pulses on the selected pulse generator unit.
Usage
istat = int pgu_trig_burst(int
instr_id
, int
unit
, long
count
);
instr_id
The instrument identification code
unit
Pulse generator unit number (input):
1
,
2
,
3
, or
4
, depending on system
configuration
count
The number of pulses to output:
1
to
65535
(input).
Details
This command triggers a burst of pulses that have been previously defined. Unlike the
pgu_trig
command, this command takes a unit number and a number of pulses as arguments so that you can
trigger a stream of pulses on a specific pulse generator unit.
To trigger multiple pulse generator units, you can sum the unit numbers designated to the pulse
generators as listed in the following table.
Number
Pulse generator unit
4096
PTRIG1
8192
PTRIG2
16384
PTRIG3
32768
PTRIG4
This command returns a
0
if executed without error; a negative number indicates an error.
Example
istat = pgu_trig_burst(2, 107)
Triggers 107 pulses on pulse generator unit number 2.
