Abstract :
This paper describes two techniques (crystal switch and pulsed receiver) for measuring peak power. Both systems sample the unknown RF pulse. The sample is then compared to an identical sample taken from an accurately known CW signal. A coherent detector is used to compare the levels of the two samples. Measurement can be made on pulse power levels down to ¿60 dbm. Neither measurement system is affected by the rise and fall time of the unknown RF pulse. Pulse widths of 0.3 ¿sec or greater can be measured with an accuracy approaching 3 per cent at 0 dbm and 5 per cent at ¿60 dbm.
