The CAS-108D is an 8-channel plug-in signal conditioning board for use in Curtiss-Wright’s EDAU-20XX and CDAU-20XX products. The board is intended for applications that require significant signal conditioning flexibility and simultaneous sampling capability. The board provides programmable digital presample filtering and user-programmable gain. The conditioned analog signal is digitized at up to 16-bit resolution for transmission in the system PCM output format.
