The Keysight 55280B Linear Measurement Kit is a precision measurement component of the Keysight 5530 Laser Calibration System, engineered to measure linear displacement and velocity along machine travel paths. It enables characterization of positioning accuracy, repeatability, and directional errors in numerically-controlled machine tools and coordinate measuring machines. The 55280B is functionally identical to the 55280A but excludes the transit case.
