16-channel receiver R-693
The basic modification of the product R-693 is a 16-channel radio receiver, operating by means of a single antenna input and constructed on the basis of the direct digital-analog transformation principle.
The product is meant for being applied as a part of the stationary automated receiving HF hardware complexes.
The main functional hardware components are:
- 16-channel receiver module operating in the range from 1,5 to 30,0 MHz and providing preselection of the received signals using reconfigurable preselector, the pass band of which is determined automatically on the basis of the received receive chains frequencies, and forming of the unified digital receive chains of the output in pass bands 3,1 and 40 kHz;
- 16-channel program computer-based demodulator;
- Analog-output module for 16 reception channels (AOM);
- Local information network commutator (LIN);
- Operator console.
Receivers account the possibility of reprogramming the main features of the product using the unified interface (SDR technology is realized).
The construction of the product is a standard 19-inch stand, which includes all the components mentioned above except for the operator console.
