Driver Functions

hp4156b_setPbias

This function specifies the pulse output channel for the pulsed spot measurements

and the staircase sweep with pulsed bias measurements, and sets the parameters.

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

synchronizes with the staircase sweep output by the hp4156b_setIv function.

Syntax ViStatus _VI_FUNC hp4156b_setPbias(ViSession vi, ViInt32 channel,

ViInt32 mode, ViReal64 range, ViReal64 base, ViReal64 peak, ViReal64 width,
