hp4156b_setPiv
This function specifies pulsed sweep source and sets the parameters. The pulsed
sweep source is used for the pulsed sweep measurements.
Filter of the pulse source must be set to off by using the hp4156b_setFilter function.
Syntax ViStatus _VI_FUNC hp4156b_setPiv(ViSession vi, ViInt32 channel, ViInt32 mode,
ViReal64 range, ViReal64 base, ViReal64 start, ViReal64 stop, ViInt32 point,
ViReal64 hold, ViReal64 width, ViReal64 period, ViReal64 comp);
NOTE range, base, start, stop, comp parameters
Available values depend on the unit. See “Parameters” on page 2-6.
Parameters vi Instrument handle returned from hp4156b_init( ).
