Calibration Procedure using Agilent 8480 Series Power
Sensors
The following procedure describes how you calibrate the power meter with
the Agilent 8480 series power sensors.
Note V8486A and W8486A sensors
For most 8480 series sensors the correct (A type or D type)
linearity correction table is automatically selected. However, for
the V8486A and W8486A sensors the automatic selection must be
overriden and the D type correction selected. Subsequent
connection of another A type sensor will result in a warning
message stating that “Linearity Override May be Required”.
To select the linearity type to be applied:
Press , , or .
There are a variety of methods to connect the power sensors to the power
meter depending on the model of power sensor you are using. Refer to
Table 2-1 on page 2-11 for details on connecting different power sensor
models.
1. Press .
2. Verify the reference calibration factor of your power sensor with
that displayed under . The value shown is obtained from
the sensor calibration table if one is selected, otherwise it is the
last value set or the default of 100%. If the value is not correct
press . The power meter displays the reference calibration
factor in a pop up window. Modify this reference calibration factor
(see below) as desired.
■ Use or to modify the digit on which the cursor is
currently positioned.
■ Use or to move to other digits.
3. To confirm your choice press .
4. Connect the power sensor to the POWER REF output.
