Agilent / Keysight 86100D Infiniium DCA-X Wide-Bandwidth Oscilloscope Mainframe

The Keysight 86100D Infiniium DCA-X is a modular wide-bandwidth oscilloscope mainframe engineered for high-speed digital and optical signal analysis. It supports up to 16 channels simultaneously across data rates from 50 Mb/s to over 80 Gb/s, with extensible bandwidth configurations exceeding 100 GHz through plug-in modules. The platform delivers ultra-low intrinsic jitter - as low as 90 fs RMS at 44 GHz - and noise performance down to 250 µV, making it ideal for optical transceiver characterization, ASIC/FPGA/IC testing, and serial bus analysis including TDR/TDT and S-parameter measurements.
