Establishing a relative offset value
You can use the 2470 to automatically determine the relative offset, or you can assign a specific
relative offset value.
Automatically acquiring a relative offset value
When you automatically acquire a relative offset value, the 2470:
• Makes a new measurement.
• Stores the measurement as the new relative offset level.
Before acquiring the offset, apply the signal that you want to offset the measurement by.
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 Acquire. The relative offset value is displayed to the right.
When you select Acquire from the front panel, Rel is automatically set to On unless an overflow
reading is detected.
You can also enable or disable the relative offset feature through the SETTINGS swipe screen Rel
option.
Using a remote interface:
• SCPI commands: Refer to [:SENSe[1]]:<function>:RELative:ACQuire (on page 12-56) and
[:SENSe[1]]:<function>:RELative:STATe (on page 12-57).
• TSP commands: Refer to smu.measure.rel.acquire() (on page 14-144) and
smu.measure.rel.enable (on page 14-145).
When the relative offset is selected, the REL annunciator to the right of the measurement is
displayed.
