The Keysight 86106A is a dual-channel plug-in module for the 86100 series digital communication analyzers, delivering integrated optical and electrical measurement capability in a single instrument. The optical channel spans 30 GHz bandwidth across 1000–1600 nm with calibrated reference points at 1310 nm and 1550 nm, supporting 9/125 µm single-mode fiber inputs. The electrical channel offers selectable 18 GHz or 40 GHz bandwidth with transition times of 19.5 ps and 9 ps respectively. Together, these channels enable precise, simultaneous analysis of high-speed optical and RF signals in telecommunications, data center, and research applications.
