Agilent/Keysight V11644A

The Agilent/Keysight V11644A is a mechanical waveguide calibration kit engineered for precise network analyzer calibration across the 8.2 to 12.4 GHz band in WR-90 waveguide systems. It delivers systematic error correction through a suite of calibration standards - shorts, termination loads, and precision shims - enabling 1-port and 2-port calibration methodologies including TRM (Thru-Reflect-Match) techniques. The kit is optimized for measurement environments where accuracy and traceability are critical.
