Offering receiver characterization for single- and multi-lane devices operating up to 16 and 32 Gbps, J-BERT M8020A accelerates insight into digital designs. Integrated in each pattern generator channel, adjustable intersymbol interference (ISI) function enables channel loss emulation and streamlines test setup by eliminating need for external cabling and external ISI trace switching. ISI option supports range of loss up to 25 dB and 16 GHz with linear loss curves and fine step resolution.
