400G Bit Error Ratio Tester
Classification:
400G high-speed bit error ratio test system (PSS BERT19881) is a high-speed signal error performance analyzer for multi-channel PAM4 and NRZ applications. It supports up to 8x56Gb/s PAM4 signal testing, also 10G~28Gb/s NRZ signal testing. The device includes 8-channel PPG, 8-channel ED receiver and transmitter signals, which can work simultaneously or independently. The transmitter includes a multi-level pre-emphasis adjustment mode, which can perform functions such as eye shape adjustment for PAM4 signals. The receiver includes 0~9dB CTLE equalization adjustment, and also supports FFE and DFE equalization functions. It supports FEC functions KP4/KR4 FEC protocol, Symbol Errors analysis, with SNR monitoring function.
