The cam generator TBCG3-CN is primarily designed to verify performed emission test settings. It is a useful tool to validate correct operation of the LISN, correct setup and correct configuration of the spectrum analyzer.
A rotary switch lets you choose between five fixed cam frequencies and an external excitation input with a frequency range of 5 kHz to 300 MHz.
The cam generator is supplied with country-specific adapter cables, which connect to the DUT socket on the (non-powered!) LISN.
The unit 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 an N female connector.
The housing is milled from solid aluminium. A ¼” – 20 UNC thread in the cam panel accepts standard rack bolts.
