The Keysight 86108B is a Precision Waveform Analyzer plug-in module designed for the 86100C and 86100D Infiniium DCA wide-bandwidth oscilloscope mainframes. It integrates two high-bandwidth electrical channels, an ultra-low-jitter precision timebase, and high-performance clock recovery, making it an industry-standard solution for the accurate analysis of high-speed electrical communication signals up to 32 Gb/s with outstanding residual jitter of less than 50 fs RMS.
