Agilent / Keysight Q11645A Verification Kit, WR-22

The Agilent/Keysight Q11645A Verification Kit is a precision calibration tool for verifying waveguide components and systems in the WR-22 band. It delivers standardized measurement references with NIST-traceable uncertainties, enabling accurate characterization of adapters, attenuators, terminations, and filters across 33.00 GHz to 50.00 GHz. The kit streamlines verification workflows in R&D and production quality control environments by providing known impedance and attenuation standards alongside baseline waveguide references.
