The IFR Aeroflex NAV-2000R-80 is a NAV/COMM signal generator engineered to simulate navigation and communication signals for avionics receiver testing and calibration. Operating across 150 kHz to 450 MHz, the instrument delivers precise modulation control for VOR, Localizer, Glideslope, ADF, Marker Beacon, and COMM modes. Output power ranges from -120 to +7 dBm with 10 Hz frequency resolution and spectral purity of 0.001 DDM. The unit supports programmable Morse Code identification, variable modulation tones, and SELCAL capability for HF/VHF/UHF applications. IEEE-488 bus control enables full automation and integration into test systems, with optional Collins 479S-6A command set compatibility. Up to 249 user-stored test setups (49 per mode) accelerate recurring calibration workflows. The bright electroluminescent display provides immediate feedback during manual operation. Bench or rack-mounted configurations accommodate diverse lab and field environments.
