Automatically acquiring a relative offset value
When you automatically acquire a relative offset value, the 2281S performs the following actions:
Makes a new measurement.
Stores the measurement as the new relative offset level.
Before you automatically acquire a reference for relative offset, make sure that the trigger model is
not in idle mode, set the arm and trigger source to immediate, and turn on the output. For more
information about the trigger model, see
(on page 3-30).
Using the front panel:
1. Select the measurement function. The relative offset will be applied to this function. For more
information, you can refer to
(on page 2-96).
2. Press the
MENU
key.
3. Under Measure, select
Rel/Filter
.
4. Select the button next to
Rel Acquire
and press
Enter
.
Using SCPI commands:
:SENSe:FUNCtion "VOLTage"
:SENSe:VOLTage:REFerence:ACQuire
:SENSe:VOLTage:REFerence:STATe ON
To acquire a relative offset value for another function, replace
VOLTage
with
CURRent
or
CONCurrent
.
Displayed measurements
When you make measurements, the instrument may perform operations on the measured values that
affect what you see on the display and the measurements that are stored in the buffer.
The operations that can affect the measurement display are:
Filter operations
Relative offset
Math operations
If none of these operations are set, the value that is displayed on the front panel is the actual
measurement reading.
