BERT 1A881 _ 800G High Speed Bit Error Rate Tester

PRECISE 800G high-speed bit error tester is a high-speed signal error performance analyzer for multi-channel PAM4 and NRZ applications. It supports up to 8x56GBaud and is mainly used for optical testing such as R&D and testing of 800G, 400G, 200G, and 100G modules.

The transmitter includes a multi-level pre-emphasis adjustment mode, which performs eye shape adjustment for PAM4 signals. The receiver includes 0~9dB CTLE equalization adjustment, which supports equalization functions such as FFE and DFE.

Supports FEC function, performing PRBS error checking and correction, Symbol Error distribution viewing, KP4/KR4 FEC protocol, and has SNR monitoring function.
