Abstract :
With a new measuring system, the attenuation range of the national RF standard attenuation measuring equipment at the Physikalisch-Technische Bundesanstalt (PTB), Germany, has been extended to 60 db in the waveguide bands R 220 and R 320. Most of the system is automated to shorten the calibration and measurement time. The total uncertainty of measurement is estimated to be 0.0027 dB per 10 dB attenuation
