400G PAM4 High Performance Error Tester Signal Coding Mode:NRZ/PAM4
The 400G PAM4 bit error tester is a high-performance bit error tester for 400G high-speed optical transceiver module testing.
Performance characteristics:
1, signal coding mode: NRZ and PAM4, can automatically switch between NRZ and PAM4 signals freely.
2, eight-channel synchronous output, used to test 6.144G, 10G, 40G, 100G, 200G and 400G products, error test can be independent or eight-way synchronous test.
3, Support continuous error detection and timing error monitoring, support KP4/KR4 hardware FEC function.
4, NRZ support rate: 6.144, 10.3125, 25, 25.78125, 26.5625, 28.05 Gpbs.
5, PAM support rate: 14.0625, 26.5625, 28.9GBd.
6, NRZ support code type: PRBS7, 9, 10, 11, 15, 23, PRBS31, User Defined.
7, PAM4 support code type: PRBS11Q, 13Q, 15Q, 20Q, 23Q, 31Q, 49Q, 58Q, SSPRQ, JP03A, JP03B, User Defined.
8, the clock frequency of the default 4 frequency division, support a quarter, 1/8, 1/16, 1/32, 1, 64, 1 / frequency than 128 points.
9. Communication mode: USB to HID. There is no need to drive, communicate with the device through the PC upper computer software, set the bit error meter and test the bit error rate.
