Test Instrumentation Range Brochure

 

Description

The YRS 03 is a multi-mode, broadband noise and comb source that is capable of producing a continuous noise output or a comb of frequencies within the 10 MHz to 6 GHz range, with the 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, and the frequency accuracy of measurement of equipment to be checked.

The YRS03 is a compact and battery powered, allowing operation as an electrically small source, which minimises the effect of the YRS03 itself when characterising the electromagnetic environment. 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 unit’s output connector.

Three antennas, one monocone and two monopole optimised for different frequency bands, are available. The YRS03 is an ideal source for carrying out checks on Open Area Test Sites (OATS) and fully- or semi-anechoic chambers.

Features

Selectable noise or comb output •Flexibility across a range of applications
Stable output •Repeatable measurements
10 MHz to 6 GHz output •Applications across a broad frequency spectrum
Conducted and radiated options •Evaluation of both conducted and radiated systems
Compact and portable •Comparisons between sites and environments
Battery powered •No power or interconnecting cable effects on measurements

Applications

  • Investigation, characterisation and comparison of different measurement environments such as OATS, FAR or SAC.
  • Validation and verification of radiated and conducted measurement systems, such as:
    • Open Area Test Sites (OATS)
    • Fully Anechoic Rooms (FAR)
    • Semi-Anechoic Chambers (SAC)
    • Gigahertz Transverse ElectroMagnetic (GTEM) cells
  • Reference source for:
    • Daily pre-test checks as required by the accreditation authorities e.g. ISO 17025, DEF STAN 59-411
    • Long-term performance monitoring
    • Cable position investigation
    • Investigation of screened room behaviour
    • Characterisation of filter performance
    • Cable loss measurements
