Now featuring Auto-BERT, an automated test application for quick and simple construction and display of 'waterfall' performance curves!

Just enter a starting and ending Eb/No, a step size, and threshold. With the advanced capabilities of the SE-4255 you can sit back and watch the curve built. Add additional curves on the same plot for simple comparison and characterization of products, systems, links, etc.

SRI's new SE-4255 RF Exciter & Test Signal Simulators combine a state-of-the-art high data rate digital wideband waveform modulator with a high performance RF upconverter and full-featured link test capabilities to produce transmission-ready signals in the Baseband, Upper L-, Lower L-, and both Transmit and Receive S-Band frequency ranges. Combining these capabilities in one small, simple-to-use unit allows quick and accurate setup, testing and operation without in-depth system knowledge.

Visit SRI in Booths 1012/1014 at ITC/USA 2008 to see how the SE-4255 and other SRI Satellite and Range Telemetry Products can help you lighten your load.
