TBCG4 General Purpose Comb Generator

The TBCG4 is a general purpose harmonic comb generator with a switchable base frequency of 20
MHz, 10 MHz or 5 MHz. It generates a flat comb spectrum up to 1 GHz. The comb generator is
powered via a USB C socket on the rear panel.
The TBCG4 is designed and characterized to serve asa versatile lab tool for measuring cable
resonances, shielding effectiveness, filters, crosstalk, EMC test setups and more. Comb generators
are commonly utilized as a general purpose source for wideband RF signals or narrow pulses with a
fast rise time.
