800G PM4 BERT Tester Data Output Eye Diagram Crossing Point NRZ
U9268Q 800G PM4 BERT Tester
1. Signal coding mode: NRZ and PAM4, which can automatically switch freely between NRZ and PAM4 signals.
2. eight channel synchronous output, used for testing 6.144g, 10G, 40G, 100G, 200G and 400G products, error code test can be independently or eight channel synchronous test.
3. support continuous error code detection and timing error code 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 supports 14.0625, 26.5625, 28.9 GBd.
6, NRZ support code type: PRBS7, 9, 10, 11, 15, 23, PRBS31, User Defined.
7, PAM4 support code types: 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. No driver is required. The PC upper computer software communicates with the device to set up the bit error meter and test the bit error rate.
