Compact and Portable: Comparisons between sites and environments; Shielding effectiveness measurements even of small enclosures.
Battery powered: No power or interconnecting cable effects on measurements

CGE01R: Radiated version with integrated wideband monopole antenna (as previously available).

CGE01C: With SMA output for direct connection

Radiated Emissions

Available either with an integral monocone antenna or with a detachable monocone antenna the CGE01 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 shielding effectiveness 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 CGE is housed in a plated metal cylindrical enclosure, thus ensuring uniformity of the field and can be orientated to give vertical or horizontal polarization. Additionally external antennas can be attached to the output when required.

Conducted Emissions

The York CGE01C 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.

Model CGE05 (R or C)

434MHz to 26GHz

The CGE05 is a broadband reference comb source producing frequencies within the 434 MHz to 26 GHz range, with two step sizes selectable by the user.
It is the ideal reference source for carrying out checks on fully- or semi-anechoic chambers and other E-field test environments.
The CGE05 is compact and can be run from a mains power adapter (supplied) or independently from the PPU01 battery pack to minimise the effect of cabling when characterising an electromagnetic environment.
The generator unit is housed in a metal enclosure so that it can be mounted in direct electrical contact with a ground plane, as may be required by some tests.
The comb signal allows for both the reference and noise floor signal levels to be viewed simultaneously, aiding dynamic range measurements.
The CGE05 is equipped with a precision SMA output connector to which an antenna can be fitted for generating radiating E-fields.
