Comb Generator Emitter - CGE03

The Eurofins York Comb Generator Emitter 03 (CGE03) is a compact, battery powered, reference signal source that generates a broadband conducted output 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.
