pulse_exec

This command is used to validate the test configuration and start test execution.

int pulse_exec(long mode);

Standard and Segment Arb

Use this command to validate the test configuration, select the simple or advanced mode, and

execute the test. If there are any problems with the test configuration, the validation will stop and the

test will not be executed.

The pulse_exec command is nonblocking, which means that if this command is called to execute

the test, the program continues and does not wait for the test to finish. Therefore, after calling

pulse_exec, the pulse_exec_status command must be called in a while loop to ensure the

test is complete before fetching data or exiting the user test module (UTM).

There are two commands that affect a pulse test while it is running:

The pulse_remove command removes a PMU channel from the test.

The dev_abort command aborts the test.

The Internal Trigger Bus trigger source (see pulse_trig_source command) is used only by the

4220-PGU and 4225-PMU for triggering. The pulse_exec command automatically uses the internal

trigger bus. A trigger input to start a pulse_exec test is not available.

Do not exit the user module while the test is still running. Incorrect readings or device damage may

The mode of execution:

PULSE_MODE_SIMPLE or 0: No analysis performed during testing; no

ranging, no load-line effect compensation, and no threshold checking

PULSE_MODE_ADVANCED or 1: Enables the analytical sweep engine and

incorporates the use of any combination of the various options for the

standard (2-level) pulse mode
