Agilent 86100A Digital Communication Oscilloscope

The Agilent 86100A Infiniium DCA is a high-speed oscilloscope that also functions as a digital communications analyzer and a time-domain reflectometer. The combined oscilloscope/analyzer makes complex compliance measurements in the shortest amount of time possible, eliminating the need for learning cumbersome compliance test procedures. Compliance measurements that once required many steps can now be performed in a single step. This new capability, along with an intuitive interface, allows engineers to perform entire procedures, such as compliance eye analysis, with the touch of a button. Now with <200 femtoseconds RMS jitter. click here.
