The TBCG3-CN comb generator is primarily designed to verify conducted emission test setups. It is a useful tool to validate the correct operation of the LISN, correct set-up, and correct configuration of the spectrum analyzer.

A rotary switch allows you to choose between five fixed comb frequencies and an external excitation input with a frequency range of 5 kHz to 300 MHz.

The comb generator comes with country-specific adapter cables, which plug into the DUT socket of the (unpowered!) LISN.

The device is powered by four AA NiMH batteries and includes an external charger.

The TBCG3-CN produces a comb spectrum with approximately 8 dB flatness in the frequency range up to 1.5 GHz and has a 50 Ohm output with a female N-connector.

The housing is milled from solid aluminum. A ¼” – 20 UNC thread in the comb panel accepts standard tripod bolts.
