pulse_dc_output
This command selects the DC output mode and sets the voltage level.
Usage
int pulse_dc_output(int
instr_id
, long
chan
, double
dcvalue
);
instr_id
The instrument identification code of the pulse card, such as VPU1 or VPU2
chan
Channel number of the pulse card:
1
or
2
dcvalue
DC voltage output value (in volts, range and load dependent):
•
5 V range:
−
5 to +5
•
20 V range:
−
20 to +20 (50
Ω load)
•
Default: N/A
Pulse modes
Standard
Details
You can set each pulse card channel to output a fixed DC voltage level instead of pulses.
The maximum and minimum output voltage is range dependent. See
pulse_vhigh
and
pulse_vlow
for details.
The
pulse_vlow
,
pulse_vhigh
, and
pulse_dc_output
commands set the voltage value
output by the pulse channel when it is turned on (using
pulse_output
). If the output is already
enabled, these commands change the voltage level immediately, before the pulsing is started with a
pulse_trig
command.
Example
pulse_dc_output(VPU1, 1, 10)
Selects channel 1 DCV output and sets voltage to +10 V.
