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?
400 watts
Peak Envelope Voltage (PEV) = Vpp / 2 = 400V / 2 = 200V. PEP = (PEV^2) / (2 × R) for a sinusoidal envelope peak. PEP = (200^2) / (2 × 50) = 40000 / 100 = 400 watts.
