agb1500_setNthSweep
Syntax ViStatus _VI_FUNC agb1500_setLoadCorrMode(ViSession vi, ViInt32 channel,
ViInt32 mode);
Parameters vi Instrument handle returned from agb1500_init( ).
channel Slot number of the slot that installs the MFCMU to be used. See
Table 2-2. channel=-1 detects the slot automatically.
mode 0: CMU load correction function ON.
1: CMU load correction function OFF.
agb1500_setNthSweep
This function sets the synchronous sweep source for the multi channel sweep
measurements. Up to nine synchronous sweep sources can be set by entering this
function for each channel. The source output is the staircase sweep, and
synchronizes with the primary sweep source output. The agb1500_setIv function
must be executed before this function.
To perform the multi channel sweep measurements, execute the agb1500_setIv
function to set the primary sweep source (first sweep source), and execute the
agb1500_msweepIv or agb1500_msweepMiv function to start measurement. The
agb1500_msweepMiv function allows to use multiple measurement channels.
Syntax ViStatus _VI_FUNC agb1500_setNthSweep(ViSession vi, ViInt32 n,
ViInt32 channel, ViInt32 mode, ViReal64 range, ViReal64 start, ViReal64 stop,
ViReal64 comp, ViReal64 p_comp);
NOTE range, start, stop, comp parameters
Available values depend on the unit. See “Parameters” on page 2-8.
Sweep type, linear or log, is set by the agb1500_setIv function. If the function sets
the log sweep, start and stop must be the same polarity.
Parameters vi Instrument handle returned from agb1500_init( ).
n Sweep source ID. 2 for the second sweep source (first
synchronous sweep source), 3 for the third sweep source
(second synchronous sweep source), ..., or 10 for the tenth
sweep source (ninth synchronous sweep source).
channel Slot number of the slot that installs the SMU to be used. See
Table 2-2.
