Keysight (Agilent) N7552A Electronic Calibration Module, DC to 9 GHz, 2-Port

The Keysight N7552A is a 2-port electronic calibration module that delivers traceable, metrology-grade calibration for vector network analyzers from DC to 9 GHz. Unlike mechanical calibration kits, this solid-state solution connects via a single USB interface to your VNA and completes calibration in under 10 seconds per standard, cutting setup time in half while eliminating operator error through full firmware automation.
