Tektronix expands its line-up of PAM4 test solutions to include comprehensive 400G electrical compliance testing for OIF-CEI-56G VSR/MR/LR PAM4 standards. The 400G-TXE software package runs on the company’s DPO70000SX real-time oscilloscopes (RTOs) that offer up to 70 GHz of bandwidth. The automated turnkey solution performs PAM4 compliance test sweeps in a single pass for shorter test times, more reliable and repeatable results, and greater ease of use. Users can evaluate PAM4 signals to specification-mandated limits and perform full OIF-CEI spec-level compliance tests. The solution includes digital clock recovery capabilities that provide trustworthy measurement results under all conditions, including signals impaired with ISI jitter or other impairments. The 400G-TXE solution is available now. For more information and a datasheet, go to http://www.tek.com/datasheet/oif-cei-56g-vsr-oif-cei-56g-mr-oif-cei-56g-lr-datasheet.
