Driver Functions
hp4156b_sweepMiv
hp4156b_sweepMiv
This function executes a multichannel staircase sweep measurement by the specified
channels, and returns the number of measurement points, sweep source data,
measurement data and the measurement status.
Before executing this function, set the sweep source setup by using the
hp4156b_setIv function. If you want to use the synchronous sweep source, execute
the hp4156b_setSweepSync function.
Syntax
ViStatus _VI_FUNC hp4156b_sweepMiv(ViSession vi, ViInt32 channel[ ],
ViInt32 mode[ ], ViReal64 range[ ], ViPInt32 point, ViReal64 source[ ] ,
ViReal64 value[ ], ViInt32 status[ ] );
Parameters
vi
Instrument handle returned from hp4156b_init( ).
channel[ ]
Channel number of the measurement unit. Enter 0 (zero) at the
end of the unit definition for channel[ ]. For example, if you use
two units, the first and second elements of channel[ ] must
specify the units, and the third element must be 0.
1 to 6 (SMU1 to SMU6), 23 (VMU1), or 24 (VMU2).
mode[ ]
Measurement mode. 1 (current measurement, only for SMU) or
2 (voltage measurement).
range[ ]
Measurement range. 0 (auto ranging), positive value (limited
auto ranging), or negative value (fixed range). See below.
For current measurement: -1E-11 to -1.0 A, 1E-11 to 1.0 A,
or 0.
For voltage measurement: -2.0 to -200.0 V, 2.0 to 200.0 V
(-0.2 and 0.2 are available for
VMU in differential mode), or 0.
point
Number of measurement points. 1 to 1001.
source[ ]
Sweep source setup data.
value[ ]
Measurement data. Two dimentional array.
status[ ]
Measurement status. 0 (no error), or 1 to 255 (error status).
Two dimensional array.
