pulse_remove
This command removes a pulse channel from the test.
Usage
int pulse_remove(int instr_id, int chan, double voltage, unsigned long state);
instr_id
The instrument identification code: VPU1, VPU2, PMU1, PMU2, and so on
chan
Channel number of the pulse card:
1
or
2
voltage
Voltage to output when removing a channel
state
Output relay state:
• PULSE OUTPUT OFF or 0: Open (disconnected)
•
PULSE OUTPUT ON or 1: Close (connected)
Pulsers

4225-PMU
Pulse mode
Standard and Segment Arb
Details
Use this command to remove a channel from a test. It is useful when there needs to be one less
channel for a pulse test that already exists. You can use it to remove a channel from a long-term
reliability test while allowing other channels to continue running.
Use the voltage and state parameters to remove a channel from a test that is running. Use the
voltage parameter to set the output voltage. For example, you may want to set the output voltage to
zero (0) when removing the channel. Use the state parameter to connect or disconnect the channel.
The output relay for the PMU is shown in the 4225-PMU block diagram in
Models 4220-PGU and
4225-PMU (on page 5-1).
When you remove a channel from a test that is not running, the voltage and state parameters are
ignored.
Example
pulse_remove(PMU2, 1, 0, 0);
This example removes channel 1 for PMU2, sets the voltage to 0 V, and opens the output relay.
