I use a good peak storage amplifier with a LM-358 and a 
conventional directional coupler, which reads peaks perfectly well 
with all types of modulating including pulse in the microsecond 
range.

I don't have to use the scope method, which is actually much less 
accurate in both resolution and from power error caused by load 
impedance changes.

As a side benefit, I don't have to do any calculations.
