pulse_dc_output

This command selects the DC output mode and sets the voltage level.

int pulse_dc_output(int instr_id, long chan, double dcvalue);

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.

pulse_dc_output(VPU1, 1, 10)

Selects channel 1 DCV output and sets voltage to +10 V.

Channel number of the pulse card: 1 or 2

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
