Section 19: Remote Commands
smuX.source.calibrateY
X = SMU channel (a or b)
Y = SMU measure function (
v
or
i
)
Where:
v
= voltage,
i
= current
Function
Generates and activates new source calibration constants.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage
smuX.source.calibratev(range, cp1expected, cp1reference,
cp2expected, cp2reference)
smuX.source.calibratei(range, cp1expected, cp1reference,
cp2expected, cp2reference)
range
The measurement range to calibrate.
cp1expected
The source value programmed for calibration point 1.
cp1reference
The reference measurement for calibration point 1
as
measured
externally.
cp2expected
The source value programmed for calibration point 2.
cp2reference
The reference measurement for calibration point 2
as
measured
externally.
Remarks
• This function generates and activates new calibration constants for the given range. The positive
and negative polarities of the source must be calibrated separately. Use a positive value for
range
to calibrate the positive polarity and a negative value for
range
to calibrate the negative
polarity.
• Typically the two calibration points used will be near zero for calibration point 1 and 90% of full-
scale for calibration point 2. Full scale for calibration point 2 should be avoided if the SMU’s
source is substantially out of calibration.
• Do not use 0.0 for a negative calibration point as 0.0 is considered a positive number.
• The two reference measurements must be made with the source using the active calibration set.
For example, source a value, measure it, and do not change the active calibration set before
issuing this command.
• The new calibration constants will be activated immediately but they will not be written to
nonvolatile storage. Use
smuX.cal.save
to commit the new constants to nonvolatile storage.
The active calibration constants will stay in effect until the instrument is power cycled or a
calibration set is loaded from nonvolatile storage with the
smuX.cal.restore
function.
• This function will be disabled until a successful call to
smuX.cal.unlock
is made.
