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.
