Range commands
The following tables summarize commands necessary to control measure and source ranges. See
the TSP command reference (on page 7-1
) for more details about these commands.
Measure range commands*
Command** Description
smuX.measure.autorangei = smuX.AUTORANGE_ON
Enable current measure autorange.
smuX.measure.autorangei = smuX.AUTORANGE_OFF
Disable current measure autorange.
smuX.measure.autorangev = smuX.AUTORANGE_ON
Enable voltage measure autorange.
smuX.measure.autorangev = smuX.AUTORANGE_OFF
Disable voltage measure autorange.
smuX.measure.lowrangei = lowrange
Set lowest I measure range for
autorange.
smuX.measure.lowrangev = lowrange
Set lowest V measure range for
autorange.
smuX.measure.rangei = rangeval
Select manual current measure range.
smuX.measure.rangev = rangeval
Select manual voltage measure range.
* See Available ranges (on page 2-81)
** 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** Description
smuX.source.autorangei = smuX.AUTORANGE_ON
