pgu_height
This command sets the peak-to-peak height of the pulse.
Usage
istat = int pgu_height(int
instr_id
, double
height
);
instr_id
The instrument identification code
height
The pulse height in volts (input)
Details
This command returns a
0
if executed without error; a negative number indicates an error.
The pulse height must be greater than -20 V and less than 20 V.
Example
pgu_height(PGU2, 2)
Sets the height of the pulse on PGU2 to 2 V.

None
pgu_init
This command initializes communication with the pulse card and sets the pulse generator to a specific set of
default conditions.
Usage
istat = int pgu_init(int
instr_id
);
instr_id
The instrument identification code
Details
This command returns a
0
if executed without error; a negative number indicates an error.
