Linacs for FEL applications require a low jitter RF path from RF source through pulsed amplifiers, klystron / modulators and cavities. For the SwissFEL project, pulsed solid state power amplifiers of the 500W / 3us class for driving the klystrons were required. For these amplifiers, a stable and reliable interferometer system was developed to measure the residual RF jitter levels to <10 ppm (parts per million) and <10 urad (0.6mdeg) rms. This paper describes the system and gives some measurement results for 3GHz, 5.7GHz and 12GHz amplifiers.
