Usage
relEnable = smuX.measure.rel.enableY
smuX.measure.rel.enableY = relEnable
relEnable
Relative measurement control. Set relEnable to one of the following values:
▪ 0 or smuX.REL_OFF: Disables relative measurements
▪ 1 or smuX.REL_ON: Enables relative measurements
X
Source-measure unit (SMU) channel (for example, smua.measure.rel.enablev
applies to SMU channel A)
Y
SMU measurement function (v = voltage, i = current, r = resistance, p = power)
Details
This attribute enables or disables relative measurements. When relative measurements are enabled,
all subsequent measured readings are offset by the relative offset value specified by
smuX.measure.rel.levelY. Each returned measured relative reading is the result of the
following calculation:
Relative reading = Actual measured reading − Relative offset value
Example
smua.measure.rel.enablev = smua.REL_ON
Enables relative voltage measurements for
SMU channel A.
