In order to prevent RF interference emitted by the mains grounding conductor from
reaching the reference mass, the grounding conductor and the reference mass are
decoupled by a PE-choke. This choke should not be bridged by the EMI test receiver,
which is also connected to the measurement reference ground. Therefore, either an
isolated or a battery-powered receiver must be used, or a PE choke must also be
placed on the PE connection of the receiver.

Connecting the equipment under test
The equipment under test is connected via the socket (1) on the front of the
R&S
AMN6500. Constant current must not exceed 16 A. For ambient temperatures
>35
°
C, external air ventilation is recommended.
The RFI voltage measurement plane is located on the front panel of the
R&S
AMN6500. The impedance gradient of connections N and L1 of the socket is
measured against the reference ground connectors (4-mm-jacks) to the left and right
(2) of the socket (1).
