400G BERT

Classification:


PSS 400G high-speed bit error test system is high-speed signal error performance analyzer for multi-channel PAM4 and NRZ applications; It supports up to 8x56Gb/s PAM4 signal test, and also support 10G~28Gb/s NRZ 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 0-9dB CTLE equalization adjustment, and support FFE, DFE equalization functions, it supports FEC functions KP4/KR4 FEC protocol, Symbol Errors analysis, with SNR monitoring function.
