hp4156b_sweepPiv
hp4156b_sweepPiv
This function executes a pulsed sweep measurement by the specified channel, and
returns the number of measurement points, sweep source data, measurement value
and the measurement status.
Array size of source, value and status should be the same together, and it must be
greater than or equal to the number of sweep points defined by the hp4156b_setPiv
function ('point’ parameter).
Before executing this function, set the pulsed sweep source setup by using the
hp4156b_setPiv function. If you want to use the synchronous sweep source,
execute the hp4156b_setSweepSync function.
Syntax
ViStatus_VI_FUNC hp4156b_sweepPiv(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.
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.
status[ ]
Measurement status. 0 (no error), or 1 to 255 (error status).
