The next experiments with a frequency step-tunable gyrotron (105-140 GHz)
and the coaxial cavity gyrotron (134-170 GHz) make it necessary to build
up a revised frequency diagnostic system at the Forschungszentrum
Karlsruhe. In this system the gyrotron output signal is converted down
to the IF-band (<18 GHz) signal which is splitted for a coarse frequency
measurement with a filterbank and a fine measurement (<2.5 GHz) with a
frequency time analyzer.
