Calibration Procedure Using 8480 Series Power Sensors and N8480
Series Power Sensors (with Option CFT)
The following procedure describes how you calibrate the power meter with the
8480 Series power sensors and N8480 Series power sensors with Option CFT.
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 2-5 on
page 107 for details on connecting different power sensor models.
1 Press , and .
Verify the reference calibration factor of your power sensor with that displayed

V8486A, W8486A, and E8486A-100 sensors
For most 8480 Series sensors, the correct (A type or D type) linearity correction
table is automatically selected. However, for the V8486A, W8486A, and
E8486A-100 sensors, the automatic selection must be overridden 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 , and to select either or .
