CGE03 Product Information

Test Instrumentation Range Brochure


The Comb Generator Emitter 03 (CGE03) is a compact, battery-powered, reference signal source that generates a broadband conducted output from 900 MHz up to 40 GHz. When used as a verification reference source, the known output allows unknowns within systems or components to be measured or calculated.

The CGE03 is supplied with a 50 Ω 2.9 mm output connector for direct connection to conducted test systems, or to an external antenna in order to generate test fields for evaluating radiated emission test systems.

The CGE03 harmonic steps can be switched between 900 MHz and 1 GHz as standard, allowing more frequency points to be measured than is possible with a fixed-frequency source.


Stable output•  Repeatable measurements
900 MHz to 40 GHz output•  Applications across a broad frequency spectrum
 •  Applicable to harmonics of high frequency systems
Compact and Portable•  Comparisons between sites and environments
Battery powered•  No power or interconnecting cables affecting measurements


  • Reference source for:
    • Daily pre-test verification checks if required by the accreditation authorities
    • Long-term performance monitoring
    • Spectrum analyser / receiver pre-checks
  • Characterisation of filter performance
  • Cable loss measurements
  • Measuring amplifier gain and bandwidth
  • Radiated measurement system validation and verification (requires an additional antenna)
  • Inter-laboratory tets programs
  • Proficiency test programs
