No power or interconnecting cable effects on measurements

The YRS02 is a broadband noise and comb source that is capable of producing a continuous noise output from 9 kHz to 1 GHz, or a comb of frequencies within the 5 kHz to 1 GHz range, with step size being selected by the user. The noise generator enables observation of details over the full spectral range, while the comb generator allows for the reference signal output and noise floor to be viewed simultaneously.

Radiated Emissions

For radiated operation two monopole antennas, optimised for different frequency bands, are available which attach to the top of the unit. The YRS02 is an ideal source for carrying out checks on open area test sites (OATS) and anechoic chambers.

The YRS02 is compact and battery powered, allowing operation as an electrically small source, which minimises the effect of the YRS02 itself when characterising the electromagnetic environment. The YRS02 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.

Conducted Emissions

An N-type connector provides a direct 50Ω matched output, which can be used to carry out checks on conducted measurement systems. Two adaptors are available as optional accessories:
