Calculate the Power Calibration Delta value. The delta value is the power meter measurement minus
the Advantest measurement.
Delta = A - B
Example: Delta = -0.7 dBm - (-1.25 dBm) = 0.55 dB
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).
