Usage

relValue = smuX.measure.rel.levelY

smuX.measure.rel.levelY = relValue

relValue

Relative measurement offset value

Source-measure unit (SMU) channel (for example, smua.measure.rel.levelv

applies to SMU channel A)

SMU measurement function (

= voltage,

= current,

= resistance,

= 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 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.
