SKE_R single-channel radio receivers for monitoring systems of digital communication lines 0.02 GHz to 40 GHz

SKE_R receivers carry out reception, frequency selection, amplification and demodulation of signals with analog and frequency modulation. Signals with digital modes of modulation are converted into signals in the intermediate frequency range for further processing by digital demodulators; *

Various types of design;

Built-in self-testing and diagnostic tools;

Built-in amplitude modulated and frequency modulated signal detectors;

Console connectivity;

Remote control capability USB RS-485, Ethernet 10/100/1000 Base-T.

* The product is recommended for use in monitoring systems for radio relay and satellite communication lines.
