peak envelope power (of a radio transmitter): The average
power supplied
to the antenna transmission line by a transmitter during one
radio
frequency cycle at the crest of the modulation envelope
taken under
normal operating conditions.>>
It may be the definition, but there isn't a meter generally
available that will measure one single RF cycle at a time,
so it is unrealistic. Even a scope isn't a practical way to
read the strongest single cycle peak
Fortunately the envelope rate of change is so slow (because
of highest modulating frequency limits) that there are many
RF cycles during the crest...even on 160 meters.
What we measure when measuring PEP is the peak value of many
RF cycles, not one.
