The NBS-170 is a cryogenic noise standard operating from 110.0 to 170.0 GHz in WR-6 waveguide, with an effective output noise temperature of 76.22 K and an accuracy of +0.51/-0.90 K at 628 mmHg and 293 K. It uses a precision waveguide horn mounted to a liquid nitrogen-cooled blackbody cavity, with an automatic nitrogen purge system that eliminates the need for helium. The device requires a water bath for temperature stabilization and includes a wooden horn case, hoses, couplings, and cables. It is designed for noise source calibration, radiometer reference, and low noise amplifier measurements.
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.
