Description

Tek Box TBCG4 General Purpose Comb Generator

The TBCG4 is a versatile harmonic comb generator, suitable for various laboratory applications. It features a switchable base frequency of 20 MHz, 10 MHz, or 5 MHz, and can produce a flat comb spectrum extending up to 1 GHz. The device is powered through a USB-C socket located on its rear panel.

Designed for a wide range of uses, the TBCG4 is particularly useful in tasks such as measuring cable resonances, assessing shielding effectiveness, testing filters, and analyzing crosstalk. It also supports EMC (Electromagnetic Compatibility) testing setups. In general, harmonic comb generators like the TBCG4 are essential tools in RF (Radio Frequency) testing and measurement, providing a reliable source of wideband RF signals or narrow pulses with rapid rise times.
