Setting a relative offset value
You can set a specific relative offset value using the front panel or remote commands.
Using the front panel:
1. Press the FUNCTION key and select the measure function.
2. Press the MENU key.
3. Select Calculations.
4. For Rel, select On.
5. Select the button next to Rel Value.
6. Enter the value and select OK.
Over a remote interface:
• SCPI commands: Refer to [:SENSe[1]]:<function>:RELative (on page 6-67) and
[:SENSe[1]]:<function>:RELative:STATe (on page 6-69).
• TSP commands: Refer to smu.measure.rel.level (on page 8-171) and smu.measure.rel.enable
(on page 8-170).
Using SCPI commands:
Send the commands:
:SENSe:FUNCtion "VOLTage"
:SENSe:VOLTage:RELative <n>
:SENSe:VOLTage:STATe ON
Where <n> is the amount of the offset.
To set the relative offset for another function, replace VOLTage with CURRent or RESistance.
Using TSP commands:
Send the commands:
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.rel.level = relValue
smu.measure.rel.enable = smu.ON
Where relValue is the relative offset value.
To set the relative offset for another function, replace smu.FUNC_DC_VOLTAGE with
smu.FUNC_DC_CURRENT or smu.FUNC_RESISTANCE.
Disabling the relative offset
Using the front panel:
1. Select the measure function to which the relative offset is applied.
2. On the SETTINGS swipe screen, select the box next to Rel. An X should be displayed and the
REL annunciator to the right of the measurement is no longer displayed.
You can also disable the relative offset feature by selecting MENU > Measure > Calculations > Rel
and selecting Off.
