Usage
relValue = smuX.measure.rel.levelY
smuX.measure.rel.levelY = relValue
relValue
Relative measurement offset value
X
Source-measure unit (SMU) channel (for example, smua.measure.rel.levelv
applies to SMU channel A)
Y
SMU measurement function (v = voltage, i = current, r = resistance, p = power)
Details
This attribute specifies the offset value used for relative measurements. When relative measurements
are enabled (see smuX.measure.rel.enableY), all subsequent measured readings are offset by
the value of this attribute. Each returned measured relative reading is the result of the following
calculation:
Relative reading = Actual measured reading - Relative offset value
Example
smua.measure.rel.levelv = smua.measure.v()
Performs a voltage measurement using SMU channel A and then uses it as the relative offset value.
