Table G-4: Agilent E4406A Power Delta Calibration Procedure

Step Action

Calculate the Power Calibration Delta value. The delta value is the power meter measurement minus

the Agilent measurement.

Delta = A – B

Example: Delta = –0.70 dBm – (–1.25 dBm) = 0.55 dBm

Example: Delta = 0.26 dBm – 0.55 dBm = –0.29 dBm

These examples are included to show the mathematics and do not represent actual readings.

NOTE

Add this delta value to the TX Cable Loss value during In–Service Calibration.
