smuX.measure.rel.levelY
X = SMU channel (a or b)
Y = SMU measure function (v, i, r or p)
Where: v = voltage, i = current, r = resistance, p = power
Attribute Offset value for relative measurements.
Default 0
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage relval = smuX.measure.rel.levelv --Reads voltage relative offset level.
smuX.measure.rel.levelv = relval --Writes voltage relative offset level.
relval = smuX.measure.rel.leveli --Reads current relative offset level.
smuX.measure.rel.leveli = relval --Writes current relative offset level.
relval = smuX.measure.rel.levelr --Reads resistance relative offset
-- level.
smuX.measure.rel.levelr = relval --Writes resistance relative offset
-- level.
relval = smuX.measure.rel.levelp --Reads power relative offset level.
smuX.measure.rel.levelp = relval --Writes power relative offset level.
relval Relative offset value.
Remarks • When relative measurements are enabled (see smuX.measure.rel.enableY), all
subsequent measured readings will be offset by the specified relative offset value. Specifically,
each returned measured relative reading will be the result of the following calculation:
Relative reading = Actual measured reading – Relative offset value
Details See Rel in Section 6.
Also see smuX.measure.rel.enableY
Example Performs a voltage measurement and uses it as the relative offset value:
smua.measure.rel.levelv = smua.measure.v()
