Peak to peak volts into 50 ohms on a scope will be fine
if don't have access to an RF power meter.
No idea what you are up to,
but effective power can me measured this way:
signal into dummy load, measure temperature rise of dummy load.
Now try same with DC on dummy load, measure temperature rise
set DC voltage to same temperature rise.
Ohm's law gives you Watts,
