The Marconi IFR Aeroflex NAV2000R is a signal generator purpose-built for testing and calibrating avionics navigation and communication systems across a broad operational spectrum. It generates accurate simulations of ADF, Marker Beacon, VOR, LOC, Glideslope, and HF/VHF/UHF signals, serving maintenance, development, and laboratory environments with both manual and automated control.
