Avionics testing

摘要

It is inherent in this world that everything must change. In fact, it is only change that keeps design engineers off the unemployment lines. IFR, a wholly owned subsidiary of Aeroflex, Inc., has taken change to heart with the release of the IFR 4000, a compact unit designed specifically for ramp testing, though it is also suitable for bench test applications. It is a self-contained, handheld unit that performs functional testing, signal generation, and calibration of ILS (instrument landing system), VOR (VHF omnidirectional range), marker beacon, and VHF/UHF communications avionics systems. The equipment basically acts as a simulator, such as simulating a ground station or another aircraft.
