The IFR 4000 is a compact, lightweight and weatherproof unit designed for testing ILS, VOR, Marker Beacon and VHF/UHF Communications avionics systems

The IFR 4000 verifies the operation and installation of ILS, VOR and Marker Beacon receivers and VHF/UHF AM/FM and HF AM/SSB transceivers.

 • Accurate measurement of VHF/UHF transmitter, frequency, output power, modulation (AM and FM and receiver sensitivity)
• Accurate measurement of HF transmitter, frequency, output power, modulation (AM and SSB USB/LSB) receiver sensitivity
• Generation of ARINC 596 Selective Calling Tones
• Accurate measurement of HF/VHF/UHF antenna and or feeder SWR (Standing Wave Ratio)
• Simulation of Localizer and Glideslope (CAT I, II and III Ground Station) Signals with variable DDM settings
• Swept Localizer DDM for coupled Auto Pilot testing (Simultaneous Localizer, Glideslope and Marker signals)
• Simulation of VOR beacon with variable bearing
• Simulation of Marker Beacon, Selectable Airways (Z), Outer and Middle Marker Tones
• Accurate measurement of 121.5/243 MHz emergency beacon transmitter frequency, output power, modulation (AM). Headphone audio output to monitor swept tone *
• Accurate measurement of 406 MHz COSPAS/SARSAT emergency beacon transmitter frequency, output power. Decode and display of all location and user protocols *
• Guided Test capability cuts down total test time
• 5.7 inch LCD display with user adjustable backlight and contrast • Internal battery allows eight hours of operation before recharge
