Watts come to mind.

 I think what you are trying to ask is how would I measure
the total power emitted from a transmitter that is modulated by single sideband voice.
Two ways come to mind. First I would use a spectrum analyzer and crank up the
persistance then measure the area under the curve. The rest is math.  But now you have to assume a bandwidth.

The second way would be to actually calculate and sum the area under each envelope of each tone
produced and do it in real time.  Oh, and while we are splitting hairs, don't forget the carrier
suppression. A lot of ssb I hear, isn't.

As I recall, the  advent of PEP brought us cross needle peak reading power meters. 
I think an artificial horizon indicator would  yield more useable results.
