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

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.

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.
