800G BERT

Classification:


PSS 800G high-speed bit error test system is high-speed signal error performance analyzer for multi-channel PAM4 and NRZ applications; It supports 8x112Gb/s PAM4 signal test, the equipment includes 8 channels PPG,8 channels ED receiver and transfer signals can work simultaneously or independently. Transfer end includes a multi-level pre-emphasis adjustment mode, which can perform functions such as eye shape adjustment for PAM4 signals. Receiver end includes CTLE equalization adjustment,also support FFE, DFE equalization functions, it supports FEC functions KP4/KR4 FEC protocol, Symbol Errors analysis, with SNR monitoring function.
