Driver Functions

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.
