Driver Functions

agb1500_setSweepSync

This function specifies synchronous sweep source and sets the parameters. The

synchronous sweep source will be the additional staircase sweep source for the

staircase sweep measurements, the pulsed sweep measurements, or the staircase

sweep with pulsed bias measurements. The agb1500_setIv or agb1500_setPiv

function must be executed before this function.

For the staircase sweep measurements, the output synchronizes with the staircase

sweep output by the agb1500_setIv function.

For the pulsed sweep measurements, the output synchronizes with the pulsed sweep

output by the agb1500_setPiv function.

For the staircase sweep with pulsed bias measurements, the output synchronizes the

staircase sweep output by the agb1500_setIv function and the pulse output by the

agb1500_setPbias function.

Syntax ViStatus _VI_FUNC agb1500_setSweepSync(ViSession vi, 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( ).

channel Slot number of the slot that installs the SMU to be used. See

Table 2-2.

mode Source output mode. 1 (current) or 2 (voltage).

Set 1 if the agb1500_setIv or agb1500_setPiv function sets the

current output mode. Or, set 2 if the function sets the voltage

output mode.

range Output ranging mode. 0 (auto) or positive value (limited auto).

start Sweep start value (in A or V).

stop Sweep stop value (in A or V).
