The Comparison Noise Emitter V (CNE V) is a low-cost broadband noise source providing a continuous output from 9kHz to 1GHz. The stable output allows the CNE V to be used as a general-purpose reference source for characterising and verifying both conducted and radiated test environments.
The broadband nature of the output enables the observation of details within the spectrum that would be missed when using a comb generator, whilst the power output level of the unit avoids the overloads possible with impulsive noise sources that may cause damage to the sensitive input circuits of receiving equipment.
The CNE V is supplied with a 50 Ω BNC-type output connector for direct connection to conducted measurement systems. An IEC 320 adapter is also available to provide a connection to LISN equipment, as well as an RJ11/RJ14/ RJ25/RJ45 adapter for connection to telecoms ISNs.
