Electronics Test & Measurement BERT Correction Error Forward testANRITSU MP1900A series is an 8-slot modular, high-performance BERT introduces Forward Error Correction (FEC) symbol capture and Bathtub test functionality for its 116-Gbit/s PAM4 Error Detector (ED) MU196040B in its Signal Quality Analyzer-R MP1900ABERTs. With the latest application software installed, unit conducts highly accurate bit error rate (BER) evaluations of 400GbE and 800GbE communications equipment and devices used in data centers servicing 5G networks. Firm developed each software package to support the growing demand for 400GbE/800GbE network elements. Both solutions support quantitative measurement of PAM4 Signal Integrity, such as jitter tolerance tests, to evaluate the performance of high-speed devices and transceivers.
