For the very latest specifications visit www.aeroflex.com The IFR 4000 is a compact, lightweight and weatherproof unit designed for testing ILS, VOR, Marker Professional beacon and VHF/UHF Communications avionics systems. Avionics IFR 4000 Nav/Comm Industrial test set • 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 manufacturer 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 (Option 1 required) • Accurate measurement of 406 MHz COSPAS/SARSAT emergency beacon transmitter frequency, output power. Decode and display of all location and user protocols (Option 1 required) • 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 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. The IFR 4000, with its lightweight size (under 8 lbs.), long run time battery (8 hrs) and ergonomic design, will provide the user with the most portable navigational communications ramp test set on the market today. Cockpit and bench use testing can be easily interchanged. The menu driven functionality and guided test capability make this instrument extremely easy to use. Combine these benefits with the outstanding price and the user has an instrument that delivers total value. The IFR 4000 is designed to provide test support for ramp or bench environments by utilizing the supplied trimode antenna for over the air measurements or direct connection to the unit’s RF I/O port. VOR provides signal generation over the VOR band of 108.00 to 117.95 MHz with 30 Hz variable phase and 9960 Hz (sub-carrier frequency modulated with 30 Hz reference phase) amplitude modulated at 30% per tone. VOR bearing selection is provided in pre-set steps of 30 degrees and variable steps of 0.1 degrees. Localizer provides signal generation over the Localizer band of 108.10 to 111.95 MHz with 90 Hz and 150 Hz tones, amplitude modulated at 20% per tone. Variable and fixed DDM control is provided. Glideslope provides signal generation over the Glideslope band of
