Two-channel receiver
Two-channel digital receiver is meant for receiving radio signals in the range from 3 to 30 MHz and operating as a part of the automated transceiving hardware complexes for trunk radio communication.
Main features
Receive chains of the receiver able to function simultaneously and independently are characterized by having high-selective reconfigurable preselector, which allows using receivers under the influence of intense radiostation interference and during simultaneous operation of closely-spaced receivers.
Device controlling and signal outputting are performed using the unified interface according to the standard IEEE802.3u (Fast Ethernet) with transmitting physical medium based on twisted-pair cable.
Signal outputting protocol is based on the RTP protocol, and uses UDP over IPv4 as a transport protocol.
Information exchange protocol is based on the SNMP protocol.
Output signals indication is performed in the form of a couple of 32-bit even numbers. Nominal sample frequency of output signals is 48 kHz.
The product has some modifications for installing into 19”-stand, and a table modification. The product contains free slots for installing extra options.
