The U9225C 4 Channel 24.5 ~ 29.0 Gb/s (100Gb/s) pulse pattern generator and error detector is a high performance, flexible and cost effective four channel Pulse Pattern Generator and Error Detector that can operate from 24.5 Gb/s to 29 Gb/s each Channel. 4 channel 29.0 Gb/s make it total up to over more than 100 Gb/s testing capacity. It is also a standalone Bit Error Rate test solution that incorporates an internal full rate clock synthesizer.
Its small size allows it to be placed close to the Device Under Test (DUT), it can also be placed further away using the TX driver pre and post emphasis controls features to compensate for cable and interconnect losses. It also has a non destructive, integrated eye outline capture feature along with a quick eye height and width measurement capability.
