Calibrating the Power Meter
This section describes how to calibrate the power meter. You should
always zero the power meter prior to calibrating it.
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 HP 8480 series
power sensors require you to set the reference calibration factor. The
HP 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.
