Computer Controlled System of Open Resonators Having a Fast Measurement Capability at Microwave and Millimetre Wave Frequencies

A system of three open resonators which is controlled by a microprocessor is described. This facility allows simultaneous measurements of scattering phenomena to be made at chosen frequencies within the range of 10 GHz to 90 GHz. The microprocessor records the experimental data and provides output of results in graphical form either directly or in association with a mainframe computer. The system provides an advance in open resonator technology, allowing measurements to be made very quickly and at frequencies widely separated over the microwave and millimetre-wave bands.
