Driver Function Reference
hp4156b_addStressSyncPulse
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( ).
source Reference number of the stress source. 1, 2, 3, or 4.
channel Channel number of the stress source. 1 to 6 (SMU1 to SMU6),
21 (VSU1), 22 (VSU2), 27 (PGU1), or 28 (PGU2).
mode Source output mode. 1 (current, only for SMU) or 2 (voltage).
range Output ranging mode. 0 (auto) or positive value (limited auto).
base Source output value before stress start trigger (in A or V).
stress Source output value after stress start trigger (in A or V).
comp Compliance value (in V or A). It must be voltage for the current
source, or current for the voltage source.
NOTE range, base, stress, comp parameters
Available values depend on the unit. See “Parameters” on page 2-6.
hp4156b_addStressSyncPulse
This function specifies pulse stress source and sets the parameters. Up to 4 stress
sources can be used at once. Use this function and/or hp4156b_addStressSyncIv to
set the stress sources.
