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?
- A 3200 watts
- B 1600 watts
- C 800 watts
- D 6400 watts
Correct answer: B — 1600 watts. From the official ISED question bank, verified word for word.
Why
To find the output power, first turn the 800 volts peak-to-peak reading into a peak value by dividing by two, giving 400 volts. The full explanation — and one for every question — is in Pro.
