A harmonic spectrum reference signal source with a comb output characteristic generating radiated and conducted emissions up to 26GHz with 250 or 256MHz step size options.
The CGE02 is a broadband comb generator emitter with a class leading useable output from 250MHz to 26GHz. In contrast to the comparison noise emitters (CNEs), the comb generator approach has been adopted because it lends itself more to higher frequency applications. At higher frequencies the comb spectrum gives a higher output at specific frequencies which enable measurements to be made at those frequencies. It also allows a much smaller physical construction due to reduced power consumption enabling it to be used for shielding effectiveness measurements on small enclosures.
Available either with an integral monocone antenna or with a detachable monocone antenna the CGE02 can be used as a reference source for radiated emissions. The unit is battery powered so that it can be operated as an independent source without the effect of power or interconnecting cables, which would modify the fields generated. Additionally though, for making measurements of small enclosures, the actual emitter can be separated from the battery pack and operated remotely via a cable carrying only DC power. The CGE02 is housed in a plated metal cylindrical enclosure, thus ensuring uniformity of the field and can be orientated to give vertical or horizontal polarisation. Additionally external antennas can be attached to the output when required.
The CGE02C is supplied with a 50Ω SMA connector allowing it to be used either for the investigation of conducted systems or to be used with an external antenna. The known output allows unknowns within systems or components to be measured or calculated.
