Radiated Emissions

The CNE III is a broadband noise source which provides continuous output power from 9kHz to 2GHz. The broadband nature of the output enables the observation of details within the spectrum which would be missed with a comb generator. For radiated operation three monopole antennas, optimized for different bands of the spectrum, are available which attach to the top of the unit. The CNE III is an ideal source for carrying out checks on open area test sites (OATS) and anechoic chambers.

The CNE III is battery powered to allow operation as an electrically small source which minimizes the effect of the structure of the CNE III itself when characterizing the electromagnetic environment. Conversely, if desired, cables may be attached to the earth stud or the RF output to allow characterization and investigation of the effects of changes in the wiring layout on measurements. The CNE III is housed in a metal box so that it can be mounted in direct contact with a metal ground plane as may be required by some tests. The power output level of the unit avoids the overloads possible with impulsive noise sources which may cause damage to the sensitive input circuits of receiving equipment.

Conducted Emissions

In the same way that using the CNE III with an antenna can be used to check radiated measurement systems, a BNC connector provides a direct 50Ω matched output which can be used to carry out checks on conducted measurement systems. An adaptor is available (LSA02) which provides a capacitive link from the output of the CNE to a standard IEC 320 mains power connector. This allows checks and investigations on conducted measurement systems to be made, for example using a LISN or an absorbing clamp.

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 polarized 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.
