This article presents the block diagram of highly automated narrowband radiometer-spectral analyzer which operates by heterodyne signal transformation. It is being used for researching signals with continuous spectrum. The main feature of the device issuppression of the mirror channel signals and a highly automated frequency rebuild(scanning) in the range of operating frequencies. Scheme developed provides increasing of performance being microprocessor driven. Also precision and sensitivity of fast processes analysis is being increased because measurement result doesn’t depend on the receiving antenna and feeder noise levels.References
