TekBox TBCG Series Comb Generators
Benefits of the TekBox TBCG Comb Generators and Frequency Multipliers
- TBCG1 radiates a comb spectrum characterized up to 6 GHz; tolerance ±2.5 dB.
- TBCG2 optimized for moderate drive power and flatness of the spectrum in the frequency range 1 MHz to 2.5 GHz.
- TBCG3-CN comb generator to verify conducted emission test set ups.
TekBox TBCG1 Radiating Comb Generator
The TekBox TBCG1 is a radiating comb generator with an internal antenna. It radiates a comb spectrum characterized up to 6 GHz and can be used as a rough reference for testing radiated noise measurement set ups in anechoic chambers, TEM/GTEM cells, shielded chambers, etc.
TekBox TBCG2 Comb Generator and Frequency Multiplier
The TekBox TBCG2 is a comb generator and frequency mutiplier. It is optimized for moderate drive power and flatness of the spectrum in the frequency range from 1 MHz to 2.5 GHz. The recommended drive power is +10 dBm to +20 dBm. The frequency range for the control signal is 1 MHz to 350 MHz.
TekBox TBCG3-CN Comb Generator
The TekBox TBCG3-CN is a comb generator to verify conducted emission test set ups. It is a useful tool to validate correct operation of the LISN, correct set-up and correct configuration of the spectrum analyzer. A rotary switch allows you to choose between five fixed comb frequencies and an external excitation input with a frequency range of 5 kHz to 300 MHz. The TBCG3-CN produces a comb spectrum with approximately 8 dB flatness in the frequency range up to 1.5 GHz and has a 50Ω output with a female N-connector.
