The Aeroflex / IFR ATC-600A-1 avionics test equipment is a ramp tester developed to simulate the ground station or airborne environment required to test Modes A and C transponders. The ATC-600A satisfies most recent ARINC specifications and FAA regulations regarding pilot's code and encoded altitude tests and SLS, transponder receiver sensitivity, percent reply, and transmitter power, frequency. For DME testing, the ATC-600A comes with PRF measurements, precise range, power and frequency and velocity simulation.
Digital readout of XPDR code and altitude
Measures transponder frequency and checks for correct DME channel
Binary pulse information for code and altitude
Precision DME range and velocity signals, both X and Y channel
Front panel connector provides direct check of altitude encoders
Internal battery and battery charge
Checks position of XPDR second framing pulse relative to F1
