Agilent/Keysight N4693D

The Keysight N4693D is a 2-port electronic calibration module engineered for precision VNA calibration across an extended frequency range. Using solid-state, programmable impedance standards with NIST-traceable characterization data, it eliminates the need for mechanical calibration kits and reduces connection cycles. The module connects directly to compatible Keysight vector network analyzers via USB, enabling single-connection electronic calibration with full two-port capability.
