What is the output PEP from a transmitter, if an oscilloscope measures 800 volts peak-to-peak across a 50 ohm dummy load connected to the transmitter output?
1600 watts
Peak Envelope Voltage (PEV) = Vpp / 2 = 800V / 2 = 400V. PEP = (PEV^2) / (2 × R) for a sinusoidal envelope peak. PEP = (400^2) / (2 × 50) = 160000 / 100 = 1600 watts.
