hp4156b_addStressSyncIv

This function specifies the DC stress source, and sets the parameters. You can use

maximum 4 stress sources at once by using the hp4156b_addStressSyncIv and/or

hp4156b_addStressSyncPulse functions.

Syntax ViStatus _VI_FUNC hp4156b_addStressSyncIv(ViSession vi, ViInt32 source,

ViInt32 channel, ViInt32 mode, ViReal64 range, ViReal64 base, ViReal64 stress,

ViReal64 comp);

Parameters vi Instrument handle returned from hp4156b_init( ).
