Advanced technologies such as sub-nanosecond IC's, fiber optics and nucleonics require fast pulses for thorough characterization. The 8080A can, for example, generate simultaneous 1 GHz clock and simulated NRZ data for testing today's fast memories, or complementory data with up to 64 bits and fast 300pS edges for communication devises. Cost-effectivity is promoted because the 8080A's modular structure allows performance and capability to be tailored to the requirement.
