NOTE: The connection between measuring instrument and EUT power plug is made using a custom
adapter. This fixture is made by a standard male power plug, and two coaxial connectors. The central
wires of the coax connectors have to be soldered to the power wires (L, N), while the coax shields
have to be soldered to the Protective Earth conductor.
It is important to keep all connections within the adapter as short as possible, to avoid measuring
errors at high frequency.
