Driver Functions

hp4156b_setSweepSync

This function specifies the synchronous sweep source channel for the staircase

sweep measurements, the pulsed sweep measurements and the staricase sweep with

pulsed bias measurements, and sets the parameters. Synchronous sweep source is

used for the staircase sweep.

For the staircase sweep measurements, the output synchronizes with the staircase

sweep output by the hp4156b_setIv function.

For the pulsed sweep measurements, the output synchronizes with the pulsed sweep

output by the hp4156b_setPiv function.

For the staircase sweep with pulsed bias measurements, the output synchronizes the

staircase sweep output by the hp4156b_setIv function and the pulse output by the

hp4156b_setPbias function.
