Power Meter Operation
Zeroing and Calibrating the Power Meter
2-8 Agilent E4418B User’s Guide
Press , , or .
Calibrating the Power Meter
Calibration sets the gain of the power meter using a 50 MHz 1 mW
calibrator as a traceable power reference. The power meter’s POWER REF
output or a suitable external reference is used as the signal source for
calibration. An essential part of calibrating is setting the correct reference
calibration factor for the power sensor you are using. The Agilent 8480
series power sensors require you to set the reference calibration factor.
The Agilent E-series power sensors set the reference calibration factor
automatically. During calibration the wait symbol is displayed. Offset,
relative and duty cycle settings are ignored during calibration.
Note 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.
Calibration Procedure Using Agilent E-Series Power
Sensors
The following procedure describes how you calibrate the power meter with
an Agilent E-series power sensor. Since the power meter automatically
downloads the Agilent E-series power sensor’s calibration table there is no
requirement to enter the reference calibration factor. The power meter
identifies that an Agilent E-series power sensor 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.)
