What is the output PEP from a transmitter, if an oscilloscope measures 400 volts peak-to-peak across a 50 ohm dummy load connected to the transmitter output?

Why

To find the power, first turn the 400 volts peak-to-peak reading into a peak voltage by dividing by two, giving 200 volts. The full explanation — and one for every question — is in Pro.
