The Comb generator TBCG3-RN6 is primarily intended for testing radiated settings. It is a useful tool for validating the operation of antennas and preamplifiers, as well as the accurate tuning and configuration of the spectrum analyzer. It is well characterized in an anechoic chamber and the radiated emission plots can be used as a reference to compare an EUT in a non-ideal setup with the cam generator at the same location.
You can choose between five fixed cam frequencies and an external cam frequency with a range of 5 kHz to 200 MHz using a rotary switch.
The comb generator comes with two monopole antennas, a 30 cm monopole for frequencies up to 300-500 MHz and a 10 cm monopole for frequencies above that.
The radiated comb spectrum is characterized from 5 MHz – 6 GHz.
The TBCG3-RN6 has a 50 Ohm output with an N female connector. The device is powered by six AA NiMH batteries and comes with an external charger.
The housing is machined from solid aluminium. The bottom panel has a 1/4″ – 20 UNC thread that accepts standard tripod bolts.
