Details
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. Do not use 0.0 for
a negative calibration point; 0.0 is considered to be a positive number.
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 source of the SMU is substantially
out of calibration.
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 are activated immediately but they are not written to nonvolatile memory. Use
smu
X
.cal.save()
to save the new constants to nonvolatile memory.
The active calibration constants stay in effect until the instrument is power cycled or a calibration set is loaded
from nonvolatile memory with the
smu
X
.cal.restore()
function.
This function is disabled until a successful call to
smu
X
.cal.unlock()
is made.
Example
smua.source.calibratev(1, 1e-10, 1e-5, 0.9,
0.903)
SMU channel A calibrates the voltage
source using the following values:
calibrate the 1 V range, 1e-10 for +zero
source output value, 1e-5 for +zero DMM
measurement reading, 0.9 for +FS source
output value, and 0.903 for the +FS DMM
measurement reading.
