Engineers at Pentek Inc. of Upper Saddle River, N.J., are unveiling two dual-channel high-speed A-D converters that they intended as front ends for Pentek`s digital receivers and digital signal processing boards. The new boards are compatible with Pentek`s 6099 memory buffer board that accepts digital sample rates as fast as 140 megabytes per second. The first new card, the 6410-016 offers 16-bit resolution, sampling rates as fast as 10 MHz, and front-panel TTL or ECL digital outputs. The 6465 has 12-bit resolution, sampling rates of 65 MHz, and front-panel ECL outputs.
