First, power you read on RF power meters is RMS power. Peak envelope
power is the peak value of short term RMS power, average power is the
short term average of RMS power. This is why for CW PEP and average
power is the same, while for SSB and AM it is not.
If you sustitute the word AVARAGE in place of RMS this will be
correct. There is no such thing as RMS power. :)
By RMS power, I mean the power derived from RMS voltage or current as
opposed to using the PEAK value of voltage and/or current to determine
power. I suppose I could have said effective or heating power, or power
derived from RMS values of voltage or current.
It gets too confusing when we say average power is the average of the
average power.
By the way, there is no such thing as avarage power. :-)
