Narda NRA-3000 con Controllo LNB

Remote controlled spectrum and signal analyzer for integration into satellite communications systems in teleports, control centers (broadcasting, ATC, maritime, etc.), DSNG vehicles and trailers.

The LNB Control variant of the NRA-3000 generates all the standard control voltages for switching the LNB to low band or high band and to horizontal or vertical polarization. Remote control of the LNB Control feature is integrated into the standard command set of the analyzer, making it unnecessary to link any further equipment into the control software or the signal path. The LNB Control for the NRA-3000 also does not use any additional space in the rack.

The NRA can be integrated into practically any measurement environment thanks to its plain text remote control commands in ASCII and Ethernet interface. Large quantities of data can be transmitted rapidly in binary format.
