The 86100C Digital Communications Analyzer with jitter analysis (DCA-J), offers speed and accuracy for detailed jitter subcomponent analysis. The instrument integrates a digital communications analyzer with automated eye measurements, a full-function time domain reflectometer (TDR) for impedance analysis, a full-function oscilloscope with bandwidth in excess of 80 GHz and an innovative jitter analyzer for electrical and optical signals into one box. Keysight (formerly Agilent)'s new DCA-J separates jitter into its subcomponents such as random jitter, deterministic jitter, data dependent jitter, periodic jitter, inter-symbol interference and duty cycle distortion, at rates from 50 Mb/s to 40 Gb/s and higher, all with the touch of one button.
