Keysight 86118A is a dual‑channel, remote electrical sampling head module for the 86100‑series Infiniium Digital Communications Analyzer (DCA). It places the sampling electronics in two small, lightweight heads with 1.85 mm (f) inputs and over 70 GHz electrical bandwidth to minimize cabling loss and preserve fast edges.
