40 Mbps PCM Processor

Ulyssix's 3rd Generation totally integrated Tarsus3 Processor for cPCI/PXI 3U housings includes digital Bit Sync/Frame Sync/PCM Decom/PCM Simulator/IRIG Time Code Reader. The Tarsus3 advances Ulyssix’s PCM processing capability by using the cPCI/PXI 3U form factor to allow the Tarsus3 to be integrated in the same housing as other test equipment products (i.e. function generators, scopes, spectrum analyzers, etc..) running the Ulyssix ALTAIR software suite.


The Tarsus3 Processor board is powered by the latest INTEL ARRIA V with the FPGA firmware being user reconfigurable using Ulyssix supplied FlashBurn software.
