DATA

 

 

The YRS01 has been designed specifically to complement the CGE range of comb generators, and can be supplied as part of the CGE kits to provide a reference source solution covering 5 kHz to 18 GHz and over.

 

The YRS01 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 YRS01 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.

The YRS01 is compatible with the BP01 battery pack, or alternatively can be powered using an external USB supply.

Radiated Emissions

For radiated operation two monopole antennas, optimised for different frequency bands, are available which attach to the top of the unit. The YRS01 is an ideal source for carrying out checks on open area test sites (OATS) and anechoic chambers.

The YRS01 is compact and battery powered, allowing operation as an electrically small source, which minimises the effect of the YRS01 itself when characterising the electromagnetic environment. The YRS01 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.

Applications
  • Comparison between different measurement environments such as OATS or anechoic chambers
  • Radiated measurement systems validation and verification
  • Reference source for:
    • Daily pre-test checks if required by the accreditation authorities
    • Long-term performance monitoring
    • Spectrum analyzer / receiver pre-check
  • Measuring amplifier gain and bandwidth
  • Spectrum analyzer/receiver pre-check

 

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 YRS01 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.

The YRS03 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 YRS03 is supplied with a 50 Ω N-type output connector for direct connection to conducted measurement systems. For radiated operation, antennas can be attached to the units output connector.
