The Synthesys Research BertScope 12500A is a high-performance Bit Error Rate Tester engineered for characterization and validation of high-speed digital communication systems up to 12.5 Gb/s. The instrument delivers advanced error detection, jitter decomposition, and signal integrity analysis in a single integrated platform, enabling comprehensive time, error, and jitter domain measurements from the same observer point. It supports PRBS patterns from PN7 through PN31 with pattern depths to 8 Mbits, making it suitable for complex protocol validation and stressed-eye testing.
