The Keysight (formerly Agilent) 86108A Precision Waveform Analyzer is a double-wide plug-in module designed for the 86100C Infiniium DCA-J mainframe. It delivers outstanding accuracy for testing high-speed digital communications signals, featuring an integrated clock recovery system, an ultra-low residual jitter timebase, and high-bandwidth electrical channels in a single integrated unit. This setup enables simple, single-connection 'triggerless' measurements on serial data streams up to 14.2 Gb/s.
