Abstract :
A technique is described which allows the traceable measurement, at low uncertainty values, of attenuation levels in excess of 140 dB at frequencies from 0.5 MHz to 100 MHz. In addition, the technique allows the phase changes through the attenuator to be measured accurately at the high attenuation levels.<>
