Radiated Emissions

The CNE VII is a broadband noise source which provides continuous output power from 1.5GHz to 7GHz. The broadband nature of the output enables the observation of details within this band of the spectrum which would be missed with a comb generator. An integral antenna is housed in the top of the unit. The CNE VII is an ideal source for carrying out checks on open area test sites (OATS) and anechoic chambers.

The CNE VII is battery powered to allow operation as an independent source without the effect of power or interconnecting cables, which would modify the fields generated. The CNE VII is housed in a cylindrical metal enclosure ensuring uniformity of the radiated field and allowing it to be orientated to give either vertical or horizontal polarised fields. The metal enclosure also allows the unit to be mounted in direct contact with a metal ground plane as may be required by some tests.
