Rated power output is measured at the transmitter power amplifier output connector per FCC Certification information.
Any customer-required optional items such as power measuring devices and/or duplexers will introduce loss between the
transmitter output connector and the station cabinet output connector. This loss will reduce the available power at the station
connector.

Frequency stability is relative to the stability of the Reference Oscillator. Unless otherwise specified, the value shown in
this table is relative to the internal Reference Oscillator signal which is provided by the corresponding Receiver Synthesizer
Module.
