VNA Calibration Kits
ACST’s CKxx Series Waveguide Calibration Kits are precision-engineered for accurate vector network analyzer (VNA) calibration across 50 to 500 GHz. Manufactured using ACST’s high-tolerance machining technology, these kits provide reliable performance for both laboratory and production use. Each kit is compatible with frequency extenders and instruments from major VNA manufacturers, including Keysight, Rohde & Schwarz, and Anritsu. Every set includes a matched load, reference short, quarter-wave shim, straight waveguide section, and all necessary hardware in a durable protective case. Designed for precision and repeatability, the calibration kits ensure stable performance and low reflection across WR-15 to WR-2.2 waveguide bands. Optional and custom configurations are available to meet specific test or calibration needs.
