The IFR 4000 is a Flight Line or Ramp Test Set
for testing ILS, VOR, Marker Beacon,
HF/VHF/UHF Communications (NAV/COMM)
Systems, and with the ELT Option,
121.5/243 MHz Short Range Emergency
Beacons and 406 MHz COSPAS/SARSAT Long
Range Emergency Beacons.
The IFR 4000 is designed for ease of use,
portability, reliability and long service life.
The IFR 4000 may also be used for bench
testing in the General Aviation environment.
Power is derived from an internal battery. For
DC input, the DC POWER Connector is
provided for battery charging, bench operation
or servicing use.
The IFR 4000 and supplied accessories are
stored in a Ruggedized Plastic Transport
Case.
1.2 FUNCTIONAL CAPABILITIES
The IFR 4000 has the following features and
capabilities:
● Accurate measurements of VHF/UHF
transmitter frequency, output power,
modulation (AM and FM) and receiver
sensitivity.
● Accurate measurements of HF transmitter
frequency, output power, modulation (AM)
and SSB USB/LSB receiver sensitivity.
● Generation of ARINC 596 Selective Calling
Tones.
● Accurate measurement of VHF/UHF
antenna and or feeder SWR (Standing
Wave Ratio).
● Simulation of Localizer and Glideslope
(CAT I, II and III) 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.
● Guided Test capability allows instrument
setup steps to be stored.
● Accurate measurement of 121.5/243 Hz
emergency beacon transmitter frequency,
output power and modulation (AM). Audio
output for headphones to monitor swept
tone. (p/o ELT Option)
● Accurate measurement of 406 MHz
COSPAS/SARSAT beacon transmitter
frequency and output power. Decodes and
displays all location and user protocols.
(p/o ELT Option)
● Large LCD Display with user adjustable
Backlight and Contrast.
● Internal Battery allows eight hours
operation before recharge.
