The TBCG3-CN comb generator is primarily designed to verify conducted emission test set ups. It is a useful tool to validate 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 aluminium. A ¼” – 20 UNC thread in the comb panel accepts standard tripod bolts.
