Cryogenic Primary Noise Standard VivaTech s Cryogenic Noise Standard is a noise source with primary reference performance. Providing precision calibration of low noise components such as amplifiers, diode noise sources or receiver systems, it offers the ultimate in performance. The unique design provides coverage from 18 to 500 GHz in standard waveguide bands, incorporating replaceable waveguide assemblies. The standard is particularly suited to mm and sub-mm wave [THz] low noise measurement applications. Side entry design enables convenient connections to waveguide systems Vertical or horizontal waveguide orientation no mismatched bends or twists needed Low maintenance, compact temperature stabilization system no water cooling Interchangeable waveguide feed-horn assemblies provide mm to sub-mm wave [THz] coverage Automatic or manual LN2 filling-auto fill minimizes LN2 use and allows continuous operation Convenient, fully automated operation with integrated PC Real time noise temperature display at any frequency with full data logging Frequency (GHz) 18 26 26 40 90 140 220 275 275 325 325 400 400 500 Effective Noise Temperature (K) -1 83.27 82.98 83.45 83.95 85.20 81.06 79.27 76.82 72.45 71.31 69.60 Feed-horn Assembly Waveguide VTA-42-NS VTA-28-NS VTA-15-NS VTA-10-NS VTA-8-NS VTA-6-NS VTA-5-NS VTA-3.4FA-NS VTA-3.4FB-NS VTA-2.2FA-NS VTA-2.2FB-NS WR 42 WR 28 WR 3.4 WR 3.4 WR 2.2 WR 2.2 Typical Output Temperature Display 1.
