Overview
The EMC Shop is an ISO 17025 accredited calibration company with the York EMC Eurofins CNE VI Comparison Noise Emitter in stock available for sale or rental. Repair and refurbishment services available as well. Contact us now for application support.
The CNE VI is a broadband noise source that is capable of producing a continuous noise output within the 30 Hz to 6 GHz frequency range. The broadband nature of the output enables the observation of details within the spectrum that would be missed using a comb generator.
The CNE VI features two separate outputs; a 50 Ω BNC connector for the 30 Hz to 30 MHz signal and a 50 Ω N-type output connector for the 30 MHz to 6 GHz signal. For radiated operation, either output can be attached to a selection of antennas available in a range of frequency coverage and types. 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 VI is an ideal source for carrying out checks on Open Area Test Sites (OATS) and fully- or semi-anechoic
chambers. The CNE VI is compact and battery powered, allowing operation as an electrically small source, which minimises the effect of the CNE VI itself when characterising the electromagnetic environment. The CNE VI is housed in a
metal enclosure so that it can be mounted in direct contact with a metal ground plane as may be required by some tests.
