Datasheet

Overview

The VIAVI APM-424(V)5 is a MK XIIA flight line test set for testing transponder and interrogator performance on a variety of aircraft, ground and ship platforms. It is a Mode 5 and ADS-B performance and capability upgrade to the TS-4530 and APM-424 legacy test sets.

The unit closely replicates legacy operation so that existing test procedures can continue to be used, making it an upgrade path for fielded test sets. It is the MK XIIA configuration of the APM-424 family; the APM-424(V)4 MK XII Test Set is the other standard configuration.

The APM-424(V)5 supports both DoD AIMS 04-900A Option A (KIV-78) and Option B (KIV-77) crypto appliqués through interchangeable side-mounted housings, and also supports KIR-1A/1C, KIT-1A/1C and KIV-6 with the appropriate cable or adapter. An internal GPS receiver synchronizes the real-time clock to UTC.

The test set is hand-held and battery powered, with one-piece, 3-button Go/No-Go operation and self-diagnostics. Parametric test results can be stored and downloaded to a PC for review or maintenance logging, and a Windows-based remote interface GUI is available.

The product is controlled for export under the International Traffic in Arms Regulations (ITAR).
