The NBS-140 is a primary noise standard horn for the 90.0 to 140.0 GHz frequency range, with an output noise temperature of 76.17 K and accuracy of +0.44/-0.77 K. It uses a WR-8 waveguide and is designed for use with the NBS-Series cryogenic system, which includes a liquid nitrogen-cooled blackbody cavity and automatic nitrogen purge. The system eliminates annual calibrations and reduces reflection loss uncertainty. Accessories include a wooden horn case, hoses, couplings, and cables.
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.
