IFR ATC-1200Y3 Transponder & DME Test Set / Simulator

The unit is guaranteed to work for 30-days.

Unit's Serial Tag Reads:
Model Number: ATC-1200Y3
Serial Number: 1401
Input Power: 115V, 60 Hz

Introduction:
The ATC-1200Y3 Test Set includes a built-in crystal-controlled signal generator, attenuator and modulators. It is designed to operate in conjunction with a dual trace oscilloscope to provide a complete bench test of the essential characteristics of civil ATC Transponders and DME sets. The ATC-1200YE system is capable of simulating a DME or Transponder ground station.

The Test Set includes all the RF hardware to test a DME or Transponder. This hardware includes a circulator to direct the transmitter power to a dummy load and power monitor, and to direct the signal generator to the receiver in the DME or Transponder. RF monitors are included for viewing the transmitter output and the input to the receiver. A diode switch in series with the signal generator is used to modular the signal generator to obtain over 80 dB on-off ratio for the transponder interrogation and over 85 dB on-off ratio in DME mode.

Key Features:
The ATC-1200Y3 Transponder/DME Test Set permits simulation of the ground station and airborne environment on the bench.
