TX Power (Avg) [W]
This is an rms power measurement. It is only available when an HP 83236B PCS Interface
is used. This measurement is similar to the
Average Power
measurement. In fact, the
Average Power measurement is disabled if the PCS Interface is used because the interface
can measure power for both Cellular and PCS signals. Accuracy is typically
±
5% or 0.2
dB.
TX Power [W]
This is the absolute (rms) power on an AVC. It is used when a PCS Interface is not
attached. The detected signal is converted to an envelope signal voltage (power) and is
digitized. The resulting power level is calculated using the following formula:
peak power
−
2.95 dB = rms power
The RF IN/OUT port of the Test Set must be used for this measurement.
