Coaxial fixed attenuators as working standards on microwaves

摘要

Some experimental results of investigations the main components of errors of the attenuation measurements in fixed attenuators have been got. Numerical values for mismatch errors, random errors, errors caused by instability losses in coaxialconnectors have been received. Minimal potential uncertainty obtained is approximately 0,01 dB/10 dB for the frequency less than 12 GHz.
