Establishing a relative offset value
You can use the Model 2461 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 Model 2461:
•
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.
Selecting
Acquire
from the front panel automatically enables the relative offset value, 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 6-68) and
[:SENSe[1]]:<function>:RELative:STATe (on page 6-69).
•
TSP commands: Refer to smu.measure.rel.acquire() (on page 8-169) and

When the relative offset is selected, the REL annunciator to the right of the measurement is
displayed.
