Details
The
lorange
X
command is used with autoranging to limit the number of range changes, which
saves test time.
If the instrument is on a range lower than the one specified by the
lorange
X
command, the range is
changed. The 4200A-SCS automatically provides any settling delay for the range change that may be
necessary due to this potential range change.
Once defined, the
lorange
X
command is in effect until a
devclr
,
devint
,
execut
, or another
lorange
X
command executes.
Example
double idatrg[25];
.
.
conpin(SMU1, 10, 0);
conpin(SMU2, 11, 0):
conpin(12, GND, 0);
lorangei(SMU1, 2.0E-6); /* Select 2 uA as minimum */
/* range during autoranging. */
smeasi(SMU1, idatvg); /* Set up sweep measurement */
/* of IDS. */
sweepv(SMU2, 0.0, 2.5, 24, 0.002); /* Sweep */
/* gate from 0 V to 2.5 V. */
This example illustrates how you would select the bottom autorange limit.
