Calibration Procedure Using Agilent 8480 Series Sensors And N8480 Series Power Sensors With Option Cft - Agilent Technologies E4419B User Manual

Calibration Procedure Using Agilent 8480 Series Sensors and
N8480 Series Power Sensors with Option CFT
The following procedure describes how you calibrate the power meter with the
Agilent 8480 Series power sensors and N8480 Series power sensors with
Option CFT.
V8486A and W8486A sensors
N O T E
For most 8480 Series sensors, the correct (A type or D type) linearity correction table is
automatically selected. The linearity-type field on the measurement screen is grayed out.
Under the gray-out condition, the selected linearity correction table that is displayed on
the screen is irrelevant to the correct linearity correction table that is automatically
selected by power meter firmware.
However, for the V8486A and W8486A sensors (V8486A and W8486A sensors only,) 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
DTyp
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
The following procedure details the calibration for channel A. To calibrate channel B, use
N O T E
the same procedure using the equivalent channel B softkeys. To calibrate both channels
sequentially, follow this procedure for channel A, then repeat step "2" through to step "5"
using the equivalent channel B softkeys.
