M8040A-64G 64 GBaud integrated BER test solution for physical layer characterization

The Keysight Technologies Inc. M8040A is a highly integrated BERT for physical layer characterization and compliance testing. With support for pulse amplitude modulation 4-level, 3-level (PAM4, PAM3) and non-return-to-zero (NRZ) signals, and symbol rates up to 64 Gbaud (corresponds to 128 Gbit/s) it can be used for testing devices designed for 400/ 200 GbE, 800G, OIF CEI-56G and CEI-112G, PCIe ® 64/32/16/8/5 GT/s, USB 3.2, USB4, Thunderbolt™ 3 and Thunderbolt™ 4. The M8040A BERT´s true error analysis provides repeatable and accurate results, optimizing the performance margins of your devices• Data rates from 2 to 32 and 64 Gbaud
• PAM4, PAM3 and NRZ selectable from user interface
• Built-in 5 tap transmitter FFE with multiple presets to compensate loss
• Integrated and calibrated jitter injection:
RJ, LF and HF PJ (multi-tone, sinusoidal), BUJ, clk/2 jitter, sRJ, rSSC, and SSC (spread spectrum clocking)
• Forward Error Correction (FEC) encoding and error insertion for testing DUTs with FEC decoder
• Two pattern generator channels per module to emulate aggressor lane
• Linearity tests with adjustable PAM4 and PAM3 levels
• Integrated clock recovery and control of external clock recovery units N1076A/B, N1077A, N1078A
• Reference clock multiplier support with SSC extended to 64 Gbaud
