Antenna terminal conducted interference
Any undesired voltage or current generated within a receiver, transmitter, or their
associated equipment appearing at the antenna terminals.
Auxiliary equipment
Equipment not under test that is nevertheless indispensable for setting up all the
functions and assessing the correct performance of the EUT during its exposure to
the disturbance.
Balun
A balun is an antenna balancing device, which facilitates use of coaxial feeds with
symmetrical antennae such as a dipole.
Broadband emissions
Broadband is the definition for an interference amplitude when several spectral lines
a within the RFI receivers specified bandwidth.
Broadband interference (measurements)
A disturbance that has a spectral energy distribution sufficiently broad, so that the
response of the measuring receiver in use does not vary significantly when tuned
over a specified number of receiver bandwidths.
Conducted interference
Interference resulting from conducted radio noise or unwanted signals entering a
transducer (receiver) by direct coupling.
Cross-coupling
The coupling of a signal from on channel, circuit, or conductor to another, where it
becomes an undesired signal.
Decoupling network
A decoupling network is an electrical circuit for preventing test signals which are
applied to the DUT from affecting other devices, equipment, or systems that are not
under test. IEC 801-6 states that the coupling and decoupling network systems can
be integrated in one box or they can be separate networks.
