The power supplied to the antenna transmission line by a transmitter during an RF cycle at the highest crest of the modulation envelope is known as:

Peak-envelope power (PEP) is defined as the average power supplied to the antenna transmission line by a transmitter during one radio frequency (RF) cycle at the highest crest of the modulation envelope. It is the standard method used to measure the maximum output power of Single Sideband (SSB) and Amplitude Modulation (AM) transmissions. Distractors like 'mean power' or 'carrier power' refer to different measurements. Mean power averages the output over a much longer time during typical modulation, while carrier power measures the unmodulated RF output. PEP specifically isolates that brief moment of maximum amplitude.
