The YRS02 is a multi-mode reference source capable of producing a broadband noise or comb output up to 1GHz.

Selectable noise or comb output: Flexibility across a range of applications
Stable output: Repeatable measurements
5 kHz to 1 GHz output: Applications across a broad frequency spectrum
Compact and portable: Comparisons between sites and environments
Battery powered: 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:

The LSA03 provides a capacitive link from the output of the YRS02 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.
The NIA01 provides an interface to RJ11, RJ14, RJ25 and RJ45 standard connectors for conducted measurements using an ISN.

Applications
