Aeroflex Announces New IFR 6000 Ramp Test Set
Provides test capabilities for five avionics systems in a single unit

Wichita, Kan. — September 27, 2004 — Aeroflex (Nasdaq: ARXX), today announced the IFR 6000, a new ramp test set based on the highly successful IFR 4000 navigation communications test set that brought true portability and ease of use to the avionics ramp test market one year ago. One main user screen for each functional mode of operation is all that is required for most tests. The new instrument replaces three instruments with one handheld test set that is small and lightweight but can be used for ramp or bench testing. It replaces the IFR ATC-600A, IFR ATC-601 and the IFR TCAS-201 and will provide test capabilities for future systems.

"The IFR 6000 continues the revolution of ramp testing started by the IFR 4000. The new product offers incredible portability, ease of use and low price by combining three units into one. This provides our customers with substantial savings in time and money," said Jeff Gillum, director of wireless products for Aeroflex.

IFR 6000 tests transponder modes A/C/S, DME, TCAS, ADS-B and TIS-B

The IFR 6000 tests transponder modes A, C and S; Distance Measuring Equipment (DME); Traffic Alert and Collision Avoidance (TCAS); Automatic Dependent Surveillance-Broadcast (ADS-B); and Traffic Information Service-Broadcast (TIS-B). It performs transponder Modes A/C/S testing including Mode S level 1-4, FAR Part 43 appendix F (includes proposed Part 43 appendix F extension), European Enhanced Surveillance, ADS-B TX/RX and /TIS-B.

The IFR 6000 is designed to simulate the ground station or airborne environment needed to test Modes A, C and S. It will quickly and easily provide accurate measurement of transponder transmitting frequency/peak power and receiver sensitivity. Test results can be stored in memory and accessed for future analysis. One main user screen displays all data required for a complete automatic FAR Part 43 appendix F test. Test failure items are listed and the ‘MORE INFO’ feature may be used to provide a detailed easy to understand description of the failure. The test set automatically determines Mode S transponder levels and can automatically tailor some tests according to reported transponder capability. The predefined configuration files allow any class of transponder to be tested. The IFR 6000 will test any DME 1 MHz spaced X or Y channel. Measurements include interrogator transmitter frequency/peak power, Pulse Repetition Frequency (PRF), P1/P2 width and pulse spacing. The IFR 6000 provides accurate range and velocity simulation, station ident, squitter control and % reply. The RF reply level may be adjusted to perform track sensitivity tests.

About Traffic Alert and Collision Avoidance (TCAS) testing

Traffic Alert and Collision Avoidance or TCAS is a system utilized by the aviation industry to prevent aircraft from colliding and provides proximity aircraft traffic information. The IFR 6000 simulates the airborne environment necessary to allow verification/certification of proper operation of an aircraft’s TCAS I and II installations. It provides the capability of monitoring the TCAS interrogations (displaying decoded information/communication data) and generating Air Traffic Control Radar Beacon System (ATCRABS) or Mode S replies that simulate threat aircraft for bearing accuracy, TCAS traffic and resolution advisories, power and frequency, whisper/shout steps and broadcast/surveillance interrogations. The unit provides 10 selectable/programmable scenarios, a programmable parameter for intruder simulation and the surveillance monitor displays Mode S or ATCRBS interrogations. It also provides a self-test function for major sub-assemblies. Weighing less than 10 lbs., the IFR 6000 is lightweight and sleek. User friendly menus provide the operator easy access to perform required tests of Mode A/C/S, DME, TCAS I and II, ADS-B and TIS-B.
