I think you and I just read the same post.


I guess the easiest and most basic way to define it is that peak power is the peak or greatest power output that is delivered to a load at any time during operation. Peak envelope power is the average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope, under normal operating conditions of an amplitude modulated waveform. Peak is relativley easy to measure. Pep is not quite so easy.

I was waiting to see what/how others answered this before sticking my two cents in it. Glad I did now! I have seen the correct answer stated in two ways. I have seen a couple of answers that are very interesting (I'm being nice). And a couple that while exactly correct, didn't exactly address the question, but were exactly correct. About the only thing I can think of that wasn't covered in some way was the 'Peak Hold' feature of some meters.

Here's where it gets real interesting and also confusing. The way that QRN described the definition of "peak" is also often called, "peak instantaneous power". However, most people that talk about "peak" output are simply abbreviating PEP in casual conversation. It gets even worse because amateur equipment manufacturers interchange Peak and PEP all the time on the labels of their equipment. You have to read the specs to see which one they really mean. Don't feel so bad about not understanding...if the mfg's were consistent with their usage it would help a lot.

Mole thats why I brought up the Peak and (TRUE PEAK READING)

I read your post as the difference between passive PEP meters and active PEP meters. The passive meters just have a capacitor to hold the needle over, while the active meters have the circuitry that Beetle was describing.

Very few of the "passive" meters are even close when used in the "True Peak" mode. If they get lucky with the value of the capacitor they might be within +/- 10-15% of the actual PEP value. Don't forget that even the "Supreme Deity of RF Instrumentation", the Bird 43 has a maximum error of +/- 8% of full scale when the "Peak Kit" is installed (43P).

Ok I was thinking the standard peak was like 30% of what the actual True Peak reading would be but then again as stated each manufacture is going to read different.

haha....that's funny right there!
