3-48 S530-900-01 Rev. E / September 2017
pgu_current_limit
This command sets the maximum amount of current that the pulse generator unit (PGU) channel can supply
because of the pulse amplitude and load impedance.
Usage
istat = int pgu_current_limit(int instr_id, double limit);
intstr_id
The instrument identification code of the PGU
limit
The current limit value
Details
This command returns a 0 if executed without error; a negative number indicates an error.
Example
pgu_current_limit(PGU2, 1e-3)
Sets the current limit of PGU2 to 1 mA.
Also see
pgu_load (on page 3-51)
pgu_delay
This command sets the amount of time to wait after a trigger signal or command is received before outputting a
pulse (trigger delay time).
Usage
istat = int pgu_delay(int instr_id, double delay_time);
instr_id
The instrument identification code of the pulse generator
delay_time
The trigger delay time in seconds (input)
Details
This command returns a 0 if executed without error; a negative number indicates an error.
Example
istat = pgu_delay(PGU1A,0.0);
...
istat = pgu_delay(PGU1B,10e-06);
istat = pgu_trig();
Set channel 1 to have no pulse delay.
Set channel 2 to trigger a pulse after a delay of
10 µs.
