Aircraft emulation and test setup

The IFF-7300S contains all required resources and emulates all necessary signals that the aircraft exerts on the unit under test (UUT)

  • No need for an external power supply
  • The radio is completely set up and ready for full testing

Test Modes

  • Automated return-to-service testing (Level 1 / O-Level)
  • Automated module level diagnostics (Level 2 / I-Level)
  • Manual mode testing using Cobham AvComm’s proprietary VirtualPanelTM application software

Automated Testing Per OEM Procedures

  • Significant time is saved over manual testing
  • Automated “test scripts” eliminate possibility of inconsistent testing
  • Test reports are automatically stored electronically for future reference
  • Traceability of results available for audits


  • Ease of use - navigating between test modes is as easy as pushing a button
  • Affordable – no need to purchase multiple stations that take up valuable lab space; purchase only the Test Program Sets (TPS) you need today 
  • Expandable - to add test capability, simply purchase additional TPS’s 
  • In-house test/repair capability eliminates long delays and reduces number of LRU spares needed




The IFF-7300S-01/02 Test Systems are designed to test IFF Mode 4 UUTs and TACAN receiver-transmitters. The IFF-7300S-03/04 Test Systems are designed to test IFF Mode 5 UUTs and TACAN receiver-transmitters. 

The -01 and -03 versions have the DC power supply, needed for testing the majority of UUTs, and the -02 and -04 versions have the AC/DC power supply for UUTs that require AC power, such as the APX-72. Versions -03 and -04 can be expanded to test crypto appliqués by adding an external IFF-45TS.

NSN 6625-01-612-8238


The IFF-7300S-50 is a dedicated cryptographic appliqué test system configured with two IFF-45TS’s. Automatic UUT control guides the operator through the key load process.

All status flags are displayed simultaneously with red/green indication. Automated back-to-back testing offers significant time savings over manual testing. The system can be expanded to test military IFF and TACAN radios by adding an optional external power supply. The power supply is located externally (outside the rack).

  • ANSI/NCSL Z540-1 Calibration Laboratories Measuring and Test Equipment.

In addition, aviation ground support equipment (ramp or back shop), is required by the various aviation authorities around the world (including the FAA) to be maintained in accordance with the manufacturer recommendations, including calibration traceable to national standards.

What are the common issues? AVX

Как изменятся измерения, если продукт не будет откалиброван?

Tests performed with out of calibration test sets can return to service devices which are not performing to regulated specifications.

Каковы распространенные проблемы?

  • Inaccurate results: Calibration cycles greater than recommended may not yield accurate measurements
  • Inaccurate measurements resulting from uncalibrated tools may violate industry standards and violate regulatory body requirements
  • Tests found to be performed by an out of calibration test set can result in containment actions and unplanned rework
  • Devices calibrated on uncalibrated test sets may function improperly, cause interference issues violating government regulatory requirements, and/or damage other equipment
