Comparison Noise Emitter V

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.

The CNE V can also be connected to an antenna, to generate reference fields for use with radiated emissions test environments such as Open Area Test Sites and anechoic chambers. A selection of antennas that connect directly to the CNE V for this purpose is available. The CNE V is compact and battery powered to allow operation as an electrically small source at lower frequencies, thereby minimising the effect of the CNE V structure when being used as a radiating reference.
