Comb Generator Emitter 01

Description

The Comb Generator Emitter 01 (CGE 01) is a compact, battery-powered, reference signal source that generates a broadband radiated and/or conducted output up to 18 GHz. When used as a verification reference source, the known output allows unknowns within systems or components to be measured or calculated. The compact size allows small enclosures to be evaluated when used as a reference source for shielding effectiveness measurements.

The CGE 01 can be supplied with a 50 Ω SMA output connector (CGE01C) for direct connection to conducted test systems, or to an external antenna in order to generate test fields for evaluating radiated emission test systems. Alternatively, to achieve the best repeatability and compactness for purely radiated applications, the CGE 01 can be supplied with an integrated antenna (CGE01R).

The CGE01 harmonic steps can be switched between 80 MHz and 100 MHz as standard, allowing more frequency points to be measured than is possible with a fixed-frequency source. A 50 MHz/80 MHz step option is available by special request, allowing measurements compliant with chamber validations above 1 GHz according to CISPR 16.

Features:

Stable Output •  Repeatable measurements
Conducted and radiated options •  Evaluation of both conducted and radiated systems
50 MHz to 18 GHz output •  Applications across a broad frequency spectrum
50 MHz step size •  Complies with CISPR 16 validation methods
Compact and Portable •  Comparisons between sites and environments
  •  Shielding effectiveness measurements even of small enclosures
Battery powered •  No power or interconnecting cables affecting measurements

Applications:

  • CISPR 16 verifications
  • Shielding effectiveness of small enclosures e.g. PCs, servers, wireless communications equipment
  • Radiated measurement systems validation and verification
  • Reference source for:
    • Daily pre-test verification checks if required by the accreditation authorities
    • Long-term performance monitoring
    • Spectrum analyser / receiver pre-checks
  • Investigation of reverberation (mode stirred) chamber behaviour
  • Characterisation of filter performance
  • Cable loss measurements
  • Inter-laboratory test programs
  • Proficiency test programs
