The modulation monitor is like an oscilloscope in that it triggers on
the rising edge of the modulation. So the display is not quite
continuous - after every sweep it waits for the next positive transition
before starting the next sweep.
This is especially useful in CW mode so that the rising edge is stable
on successive sweeps. The P3 has a unique split-display feature where
it can show both the rising edge and the falling edge at the same time,
even when sending slowly.

The sweep width is adjusted in the "ModScale" menu entry. (Admittedly
not a very intuitive name. :=)

The envelope display is not a “snapshot”, but it isn’t quite real
time either. Close, but if you’re used to using a scope for
monitoring, you won’t call it “live”. Also, the vertical height of
the display is always normalized to the peak RF signal and there are
no sweep width/rate adjustments.
I have not experimented with the CW display modes to see how useful
they are.
My opinion is that the P3 envelope display isn’t a match for a scope,
and probably wasn’t intended to be. I do like having the SWR/PWR
indication on the P3 display, though.

Barry,
I don't have one, but I have seen them in use. The envelope
display looks like what I see on my analog 'scope. It may be
digital, but the refresh rate is fast enough you will not be able
to differentiate it from an analog display.

Can someone with the P3 TX MON please describe the envelope
display in ssb/am modes? Does it work like a real time
oscilloscope (dynamic) with changing display as you speak or does
it take static snapshots of the RF envelope? If static, how
often does it update those snapshots?
