Virginia-based Curtiss-Wright Corp. Defense Solutions Division has launched its AXN/PCM/401 data acquisition system for application in demanding flight test programs.
According to the company, the IRIG-106 high-speed pulse-code-modulation (PCM) decoder and merger and packetizer module combines information from one or two IRIG-106 PCM streams, via clocked line or self-clocking codes or into industry-standard packets.

The company explained that clocked line mode works at 40 megabits per second while self-clocking codes work at 20 megabits per second. Additionally, data from each stream passes individually into a minor frame buffer from which the system reads coherently over the backplane.
Further, the AXN/PCM/401 supports all PCM line codes and data rates to speeds of 40 megabits per second, and enables flight test engineers to combine data captured by legacy third-party PCM subsystems into modern networked FTI data acquisition systems.
The PCM decoder and merger module can packetize industry-standard PCM formats and select individual parameters from legacy PCM streams. The AXN/PCM/401 is appropriate for use in flight testing like fast jet, missile and eVTOL testing, the company explained.
