If you zero the sensor before calibrating it, the message changes to “Please Cal 
ChA” or “Please Cal ChB” depending on which channel the sensor is 
connected to.

If you calibrate the sensor before zeroing it, the message changes to “Please 
Zero ChA” or “Please Zero ChB” depending on which channel the sensor is 
connected to.

The Zero/Cal Lockout facility can be enabled or disabled through either the 
System Inputs menu or the Zero Cal menu as follows:

Press , , ,  ,

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 E-Series power sensors or 
N8480 Series power sensors (excluding Option CFT) require you to set the 
reference calibration factor. The Agilent E-Series power sensors or N8480 
Series power sensors (excluding Option CFT) set the reference calibration 
factor automatically. During calibration, the wait symbol is displayed. Offset, 
relative, and duty cycle settings are ignored during calibration.

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.
