The Agilent/Keysight 8511A is a four-channel frequency converter test set engineered for operation with the Agilent/Keysight 8510C Network Analyzer. It functions as a general-purpose magnitude and phase receiver with four RF to IF converters, enabling S-parameter measurements and advanced network analysis across a broad frequency range. The instrument accommodates multiport devices, subsystems, and antenna characterization through three measurement inputs after one input is reserved for system phase-lock. Precision 3.5 mm connectors on all inputs ensure signal integrity from 45 MHz to 26.5 GHz.
