Dense, 64 synchronous multichannel DAQ system is composed of eight 8-channel, 12-bit M9703A AXIe high-speed digitizers in 14-slot chassis that provides 13 instrument module slots (up to 104 channels) and AXIe system slot. Synchronization is realized through AXIe local bus backplane, and system supports customized, real-time signal processing and unique phase coherency. Also included is U5340A FPGA Development Kit for high-speed digitizers.
