詳細介紹

The York Reference Source (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.

This 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, and the frequency accuracy of measurement equipment to be checked.

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.

The YRS02 is supplied with a 50 Ω N-type output connector for direct connection to conducted measurement systems. An IEC 320 adapter is also available to provide a connection to LISN equipment, as well as an RJ11/RJ14/RJ25/RJ45 adapter for connection to telecoms ISNs, to provide a reference source for conducted emissions setups.

For radiated operation, antennas can be attached to the unit’s output connector. Two monopole antennas, optimised for different frequency bands, are available.

The YRS02 is an ideal source for carrying out checks on open area test sites (OATS) and anechoic chambers.
