pulse_chan_status
This command is used to determine how many readings are stored in the data buffer.
Usage
int pulse_chan_status(int instr_id, int chan, int *buffersize);
instr_id
The instrument identification code: PMU1, PMU2, and so on
chan
Channel number of the pulse card:
1
or
2
buffersize
User-defined name for the returned size value
Pulsers
4225-PMU
Pulse mode
Standard and Segment Arb
Details
Use this command to return the number of readings presently stored in the data buffer. This
command can be called while a sweep is in progress or after it is completed.
For a short sweep (test time in seconds to a minute or more), this command is typically called after
the sweep is complete to determine the total number of readings stored in the buffer. For a long test,
you can use this command to track the progress of the test. A long test is typically Segment Arb with
test time in minutes, hours, or days.
Example
pulse_chan_status(PMU1, 1, buffersize);
This command returns the number of readings stored in the buffer for channel 1.

None
pulse_conncomp
This command enables or disables connection compensation.
Usage
int pulse_conncomp(int instr_id, int chan, int type, int index);
instr_id
The instrument identification code: PMU1, PMU2, and so on
chan
Channel number of the PMU:
1
or
2
type
Type of compensation to enable:
• 1: Short
•
2
: Delay
index
Connection compensation values:
• 0: Disable all connection compensation
• 1: Connection compensation values for a setup that uses the PMU only
• 2: Connection compensation values for a setup that uses the PMU and RPM
•
3
: Custom connection compensation values (see Details)
