Available Gain Available Gain is the ratio, at a specific frequency, of power available from the output to the power in from the source.
Frequency Span Frequency Span specifies the range between the start and stop frequencies, also referred to as bandwidth
Peak Envelope Power Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.
