1. Calibrate only the source for the CALA sense steps.
2. Steps must be performed in the order shown.
3. Do not use actual 0 values for zero calibration points. Send very small values such as ±1e-30. Calibration polarities must also be
set as shown in the procedures.
4. Output must be off before changing to the CALA sense mode.
5. For Current Measure only.
6. This range is only available on the 2635B and 2636B.
Calibration commands quick reference
The following table summarizes remote calibration commands. For a more complete description of
these commands, refer to the TSP command reference (on page 9-1).
Calibration commands
Command**
Description
smuX.cal.adjustdate = adjustDate
Stores the date of the last calibration adjustment.
smuX.cal.date = calDate
Stores the calibration date of the active calibration set.
smuX.cal.due = calDue
Stores the calibration due date for the next calibration
(calDue of 0 indicates date not set).
smuX.cal.lock()
Disables the commands that change calibration settings.
smuX.cal.password = "newPassword"
Stores the password required to enable calibration
(newPassword is the new password).
smuX.cal.polarity = calPolarity
Controls which calibration constants are used for all
subsequent measurements:
smuX.CAL_AUTO (automatic polarity).
smuX.CAL_NEGATIVE (negative polarity).
smuX.CAL_POSITIVE (positive polarity).
smuX.cal.restore(calset)
Loads a stored set of calibration constants:
smuX.CALSET_NOMINAL (nominal constants).
smuX.CALSET_FACTORY (factory constants).
smuX.CALSET_DEFAULT (normal constants).
smuX.CALSET_PREVIOUS (previous constants).
