PEP power verses RMS power question

Post by wb3cez »

I,am a bit confused regarding the claims some amplifier manufacturers make regarding the output of their amplifiers. Perhaps someone can set me straight. I have a Yaesu FL-2100B amp with a pair of 572Bs as the finals. With 100 watts RMS key down input, I,am seeing about 500 watts output with the wattmeter in the RMS mode. When I switch to SSB and place the wattmeter in the PEP mode, I,am still seeing about 500 watts or so peak. Yet, some people are saying this is actually 1000 watts PEP. Seems to me, provided my wattmeter is correct, that it is still only 500 watts output regardless if it is in PEP or RMS. Comments....

I never owned a 2100b but i always thought 600 watts with 100 watts drive was what to expect.

I think you are mixing apples and oranges.

output power from a closed cw key with carrier is measured differently then

Peak Envelope Power pep in SSB mode with variable modulation..

Also there is a difference in Average power output and peak power output.
