includes the Ethernet package.
Overview
ML4025-TDR is a state of the art Digital Sampling Oscilloscope with CDR, Time Domain
Reflectometry, and Time Domain Transmission. The DSO automatically performs accurate
eye diagram analysis at 35 GHz to characterize the quality of transmitters and receivers,
implementing a statistical under-sampling technique with comprehensive software
libraries used for eye measurements, jitter analysis and processing of NRZ/PAM4 data.
The true differential TDR/TDT is used to determine the performance of different features
in many applications including Time Domain Reflectometry/Transmission, impedance
testing, propagation and time delay while testing up to 4X35 GHz true-differential
channels. It is designed for characterization as well as manufacturing.
MultiLane offers the ML4025-TDR instrument in a cPCI card format that fits into the
ML4000 MultiLane Signal Integrity Analyzer 6U cPCI Chassis.
