Pentek customers can now boost signal bandwidth with the model 6826 VME A/D converter board. The Model 6826 features single- or dual-channel data acquisition at 2 GHz samples/second with 10-bit resolution using the Atmel AT84AS008 A/D device. The board’s ability to accept either single-ended or differential inputs preserves signal integrity across a variety of analog signal sources. Dual 64-bit high-speed DDR SDRAMs provide a total of 512 MB or 1 GB of memory to store raw data in transient-capture mode. The memory can also be used as an elastic buffer for storing burst signals like radar pulses in real time and subsequent delivery to the I/O interfaces at a lower continuous rate. To support high-bandwidth data capture, the board includes several high-speed I/O channels to move the raw data off-board for storage or processing. Two or four channels of FPDP-II data ports, operating at up to 400 Mb/s each, deliver processed and de-multiplexed data through legacy connections to other VME cards.
