Description

This comparison measured a GPC-3.5 coaxial step attenuator. The attenuator was measured as a two-port device at 0 dB, 10 dB and 70 dB settings, and as a one-port device (at the same settings) with port 2 terminated with a short-circuit. Measurements were made at 1 GHz to 26.5 GHz in 1.5 GHz steps.

Eight members participated in this measurement comparision.
