32 Channel Data Acquisition And Processing System

The 32 Channel Data Acquisition and Processing system is used to acquire narrow band signals from antenna sensors. The signals are digitized on FPGA based data acquisition boards. The digital signals are processed on FPGAs and they are transferred to a processor board for further processing. The system is ruggedized for airborne application.

32 Channel Data Acquisition And Processing System

The 32 Channel Data Acquisition and Processing system is used to acquire narrow band signals from antenna sensors. The signals are digitized on FPGA based data acquisition boards. The digital signals are processed on FPGAs and they are transferred to a processor board for further processing. The system is ruggedized for airborne application.

The system is used in electronic warfare processing system for direction finding application.
