meter field and antenna parameters & nbsp; PK7-19 designed to measure levels of weak noise signal when determining the parameters of antennas radiometric methods, levels of sinusoidal signals, and to address a number of measurement problems composed IMS

Measurement of absolute values. low noise temperatures provided by the cooled nitrogen GSH, temperatures of 300 K and above - via a gas discharge GSH. To reduce the error of mismatch provides a transformer impedances, for locking the mirror channel - variable filter. Provides performance monitoring bodies of the major nodes
