Note 1: Unless otherwise stated, all values are referenced to the top of the rack.
Note 2: At maximum rated RF output power, all spurious and harmonic emissions should be at the noise floor. No
combination of IM products or any other spurious emissions generated in the transmitting equipment should exceed the
underlying noise floor in the operating band. Also, the Tx output power level is a function of the datafill parameters as well
as the RF shelf attenuator setting.
