relValue

applies to SMU channel A)

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.
