Astronics / EADS / Talon Instruments SR110 DAC Module

The SR110 is a digital-to-analog converter module engineered for the SR192 VXI Digital Test Module system. It converts digital data into analog voltage or current signals, supporting precision signal generation in automated test equipment and control applications. As a component within the modular SR192 platform, the SR110 integrates with a 2-slot VXI “C” size motherboard capable of housing up to 12 I/O modules and operating at timing rates up to 50 MHz and data rates up to 25 MHz (50 MHz multiplexed).
