About this opportunity
The Michigan Army National Guard is seeking refurbished TACAN Test Sets ATC-1400A-2 and T-1401-2 for the AN/ARM-135 Intermediate TACAN Test Set, which is used for comprehensive testing and repair of air traffic control and navigation equipment. The solicitation, identified as W50S8525QA019, requires vendors to provide microprocessor-based bench testing equipment with capabilities including automatic frequency stepping, IEEE-488-1978 GPIB interface, and digital display of transponder reply pulses. Vendors must validate the serviceability of the equipment and deliver calibrated products. The solicitation was posted on May 2, 2025, with responses due by May 12, 2025. While specific evaluation criteria are not explicitly detailed in the provided documents, the procurement appears to focus on technical compliance and equipment functionality.
The contract is set aside for total small business participation, with a specific North American Industry Classification System (NAICS) code of 423490 for Other Professional Equipment and Supplies Merchant Wholesalers. The place of performance is Selfridge Air National Guard Base in Michigan, with the procurement falling under the Department of the Army's maintenance group. While precise award values are not specified, the contract is part of the fiscal year 2025 procurement cycle and involves technical representative equipment for aircraft handling and navigation systems. The solicitation seeks to procure refurbished test equipment that can simulate both ground-to-air and air-to-air navigation scenarios, with specific requirements for mode information exchange and comprehensive testing capabilities. The procurement aims to maintain and upgrade critical air navigation testing infrastructure for military aviation operations.

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.
Automatic frequency stepping
DME Serial Data Output
IEEE-488-1978 GPIB
Digital display of decoded transponder reply pulses
Variable interference and double interrogation pulse position DME serial data output
DME serial data input
Variable interference and double interrogation pulse position
Continuous display of UUT, PRF, % Reply, Transmitter Frequency and Power
Variable SLS and Echo Pulse Level
Continuous display of UUT, PRF, % Reply, Transmitter Frequency and Power
Acceleration, velocity and range DME Modes
Remote operation via IEEE 488-1978 bus
2-out-of-5 code frequency channeling outputs
TACAN Channel: VOR pairing, or direct UHF frequency selection
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.
