Usage
relValue = smu.measure.rel.level
smu.measure.rel.level = relValue
relValue
Relative offset value for measurements:
 Current (A): −1.05 to 1.05
 Resistance (Ω): –2.10e6 to 2.10e6
 Voltage (V):
−
1100 to 1100
Details
This command specifies the relative offset value that can be applied to new measurements. When
relative offset is enabled, all subsequent measured readings are offset by the value that is set for this
command.
You can set this value, or have the instrument acquire a value. If the instrument acquires the value,
read this setting to return the value that was measured internally.
If you have math, limits, or filter operations selected, you can set the relative offset value to include
the adjustments made by these operations. To include these operations, set
smu.measure.rel.level to smu.measure.read(). The adjustments from these operations ar
e
not
used if you use the smu.measure.rel.acquire() function to set the relative offset level.
Example
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.rel.level = smu.measure.read()
smu.measure.rel.enable = smu.ON
Sets the measurement function to current,
performs a current measurement, uses it as
the relative offset value, and enables the
relative offset for current measurements.
