TBCG4
General Purpose Comb Generator
The TBCG4 General-Purpose Comb Generator is an RF signal source that generates a wide comb spectrum of harmonics from a user-defined base frequency input. It is typically used to exercise and check the behavior of RF test systems, measurement chains, filters, and receiver frequency responses. By producing many harmonics from a low-frequency reference input, the TBCG4 helps validate broadband test setups, signal paths, and instrumentation performance in both lab and field environments.
