Range commands
The following tables summarize commands necessary to control measure and source ranges. See
the TSP command reference
Measure range commands*
Command**
smuX.measure.autorangei = smuX.AUTORANGE_ON
smuX.measure.autorangei = smuX.AUTORANGE_OFF
smuX.measure.autorangev = smuX.AUTORANGE_ON
smuX.measure.autorangev = smuX.AUTORANGE_OFF
smuX.measure.lowrangei = lowrange
smuX.measure.lowrangev = lowrange
smuX.measure.rangei = rangeval
smuX.measure.rangev = rangeval
* See Available ranges
** smuX: For Models 2601B, 2611B, and 2635B, this value is smua (SMU Channel A); for Models 2602B, 2604B, 2612B,
2614B, 2634B, and 2636B, this value can be smua (for SMU Channel A) or smub (for SMU Channel B).
Source range and limit commands*
Command**
smuX.source.autorangei = smuX.AUTORANGE_ON
smuX.source.autorangei = smuX.AUTORANGE_OFF
smuX.source.autorangev = smuX.AUTORANGE_ON
smuX.source.autorangev = smuX.AUTORANGE_OFF
smuX.source.limiti = level
smuX.source.limitv = level
smuX.source.limitp = level
smuX.source.lowrangei = lowrange
smuX.source.lowrangev = lowrange
smuX.source.rangei = rangeval
smuX.source.rangev = rangeval
* See Available ranges
** smuX: For Models 2601B, 2611B, and 2635B, this value is smua (SMU Channel A); for Models 2602B, 2604B, 2612B,
2614B, 2634B, and 2636B, this value can be smua (for SMU Channel A) or smub (for SMU Channel B).
