smuX.measure.rel.levelY

This attribute sets the offset value for relative measurements.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
relValue = smuX.measure.rel.levelY
smuX.measure.rel.levelY = relValue
relValue
X
Y
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 will be offset by the value of
this attribute. Specifically, each returned measured relative reading will be the result of the following calculation:
Relative reading = Actual measured reading - Relative offset value
Example
smua.measure.rel.levelv = smua.measure.v()
