Product Overview The Keysight (Agilent) 85092C is a Type-N 50 ohm RF electronic calibration (ECal) module that removes the repetition and guesswork from vector network analyzer calibration across the 300 kHz to 9 GHz range. Instead of mating and torqueing a mechanical cal kit through open, short, load and through standards, the operator connects the ECal module once and the analyzer firmware drives the entire calibration sequence. The result is a full two-port calibration in
