The NBS-Series consists of calibration standards based on the primary fundamental physic constants of thermal noise and blackbody radiation. This provides the ultimate accuracy when measuring extremely low noise figures (noise temperatures). Simple, and versatile to use, the NBS-Series is an ideal solution for noise source calibrations, radiometer test references and low noise amplifier tests.
