Driver Functions

agb1500_msweepMiv

This function performs a multi channel sweep measurement using up to ten

measurement channels at a time, and returns the number of measurement steps,

sweep source data, measurement data, measurement status, and time stamp data.

Before this function, execute the agb1500_setIv function to set the primary sweep

source and execute the agb1500_setNthSweep function to set an synchronous sweep

source. Up to nine synchronous sweep sources can be set by using the

agb1500_setNthSweep function for each channel.

Syntax ViStatus _VI_FUNC agb1500_msweepMiv(ViSession vi, ViInt32 channel[ ],

ViInt32 mode[ ], ViReal64 range[ ], ViPInt32 point, ViReal64 source[ ] ,

ViReal64 value[ ], ViInt32 status[ ], ViPReal64 time[ ] );

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.

Enter 0 to the last element of channel[ ]. For example, if you use

two channels, set the array size to 3, specify the channels to the

first and second elements, and enter 0 to the third element.

mode[ ] Measurement mode. 1 (current) or 2 (voltage).

range[ ] Measurement ranging mode. 0 (auto), positive value (limited

auto), or negative value (fixed range). For the available values,

see Table 2-3.

point Number of measurement steps. Returned data.

source[ ] Sweep source setup data. Returned data. To disable the source

data output, set 0 (NULL pointer) instead of array.

value[ ] Measurement data. Returned data.

status[ ] Measurement status. Returned data. See “Status Code” on page

2-14. To disable the status data output, set 0 (NULL pointer)

instead of array.

time[ ] Time stamp data (measurement start time). Returned data. To

disable the time stamp data output, set 0 (NULL pointer)

instead of array.
