TACAN Test Sets ATC-1400A-2 and T-1401-2, REFURBISHED
The AN/ARM-135 Intermediate TACAN Test Set requires both the ACT-1400A-2 and the T-1401-2 to
perform intermediate testing and repair of the TACAN receiver-transmitter and the TACAN Analog-to-
Digital Adapter.
The Viavi / Aeroflex ATC-1400A-2 is a Transponder/DME microprocessor based bench tester developed
for comprehensive testing and troubleshooting of ATC (Air Traffic Control) / Transponder equipment and
DME (Distance Measuring Equipment). The ATC-1400A can be operated either manually using the
front panel controls and switches, or remotely by ATE control utilizing the GPIB interface.

The Aeroflex / IFR T-1401-2 avionics test equipment provides a full range of TACAN bearing and DME
simulation required to test and service air-to-air and ground-to-air airborne equipment in both normal and
inverse modes. The control settings on the T-1401-2 front panel determine the mode of operation.
Selecting Ground-to-Air (G/A) Mode enables the Identification and Equalizer pulse pairs. The ATC-
1400A-2 also sends mode information when connected to the T-1401-2 through the Aeroflex Bus. ATC-
1400A-2 mode information includes Identification On/Off, Equalizer On/Off, X/Y Mode and P1 and P2
pulse spacing.
Refurbished equipment only; vendor must validate serviceability and deliver product calibrated.
