The HP/Agilent 8711B is a 1.3 GHz RF network analyzer engineered for characterization of RF components across development and manufacturing environments. It delivers swept frequency measurement from 300 kHz to 1.3 GHz with 1 Hz resolution through an integrated synthesized source and transmission/reflection test set. The instrument provides dual independent display channels capable of simultaneous measurements on rectangular, polar, and Smith chart formats, including complex impedance and SWR readings.
