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
smu
X
.measure.rel.enable
Y
), all subsequent measured readings will be 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.
