Fairport, NY. Saelig Company Inc. announced the availability of two new TekBox TBCGx comb generators for EMC testing. The TBCG1 is a radiating comb generator with an internal dipole antenna and a base frequency of 100 MHz. It radiates a comb spectrum that is characterized up to 6 GHz. The comb generator is intended as a quick reference for testing radiated noise measurements in anechoic chambers, TEM/GTEM cells, and shielded chambers or for gauging the effectiveness of cable shielding and other shielding materials. With its built-in dipole antenna, the TBCG1 can be used in three orientations to emit vertically or horizontally polarized signals. It is a compact and portable device, powered by a 9-V alkaline cell. Being self-contained and battery-powered, there are no cables to disrupt the emitted field.
The harmonic amplitudes produced by the comb generator are consistent and can be used as a frequency and amplitude calibrator, insuring, for example, that a semi-anechoic test chamber is reading correctly from day to day. Simply place the TBCG1 generator on a turntable and measure specific harmonics each day and record the trend data. Loose connectors or bad cables can be detected by comparing the current readings with past data. This will fulfill the requirement for “equipment verification testing” as specified in ISO 17025, the company said.
Manufactured by Singapore-based Tekbox Digital Solutions, the TekBox TBCGx comb generators are available now from authorized North American distributor Saelig Company Inc.
