pulse_chan_status

This command is used to determine how many readings are stored in the data buffer.

int pulse_chan_status(int instr_id, int chan, int *buffersize);

Standard and Segment Arb

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

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.
