Interface Technology SR5030A Variable Voltage I/O Module

The Interface Technology SR5030A is a Variable Voltage I/O Module purpose-built for the SR5000 Digital Test Subsystem, delivering 16 independent input and 16 independent output channels with programmable voltage levels. Operating at 50 MHz with 100 ps edge placement resolution, the module supports dual pattern generation modes—RAM-backed and algorithmic—across 64K vectors per channel. It accommodates five output data formats: NRZ, RZ, RONE, RTC, and RI, with real-time stimulus, response, and compare capabilities.
