The Teledyne LeCroy SDA-820Zi-A is a 4 channel, 20 GHz Serial Data Analyzer. The SDA-820Zi-A's four channel performance at 20 GHz is pristine with exceptional rise time, overshoot, total and random jitter noise floor, and electrical noise performance. SDAII Serial Data Analysis Software LeCroy's SDAII software is optimized for fast eye diagram creation on long records, and deep insight of jitter pathologies with more parameters and analysis views to help you understand the root cause of high jitter.
