PRELIMINARY

Table H-1: 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 (see step 4 in

Table H-6).
