Calibration Procedure Using Agilent E-Series Power sensors
and N8480 Series Power Sensors (excluding Option CFT)
The following procedure describes how you calibrate the power meter with an
Agilent E-Series power sensors or N8480 Series power sensor (excluding
Option CFT). Since the power meter automatically downloads the
Agilent E-Series power sensors or N8480 Series power sensor (excluding
Option CFT)’s calibration table, there is no requirement to enter the reference
calibration factor. The power meter identifies that an Agilent E-Series power
sensors or N8480 Series power sensor (excluding Option CFT) is connected
and will not allow you to select certain softkeys. The text on these softkeys
appears grayed out.
1
Press .
2
Connect the power sensor to the POWER REF output.
3
Press , to calibrate the power meter. During calibration, the wait
symbol is displayed. (The power meter automatically turns on the
POWER REF output.)
Example
To calibrate both channels of the power meter with Agilent E-Series power
sensors or N8480 Series power sensors (excluding Option CFT) connected to
both channels.
•
Press , .
•
Connect the channel A power sensor to the POWER REF output.
•
Press , then wait till the calibration is completed.
•
Remove the channel A power sensor from the POWER REF output.
•
Connect the channel B power sensor to the POWER REF output.
•
Press , then wait till the calibration is completed.
N O T E
During calibration, the power meter automatically switches the power reference calibrator
on (if it is not already on), then after calibration, it switches it to the state it was in prior to
the calibration.
