Passive step recovery diode-based comb generator/frequency multiplier
TBCG2 is a passive step recovery diode-based comb generator/frequency multiplier. It is optimized for moderate drive power and spectral flatness in the frequency range of 1 MHz to 2.5 GHz. The recommended drive power is +10 dBm to +20 dBm. The frequency range of the drive signal is 1 MHz to 350 MHz.
Characteristic frequency range: 5MHz to 3GHz
The TBCG3-RN2 comb generator is primarily designed to test the setup of radiated emissions. It is a tool that helps verify the proper operation of antennas and preamplifiers, as well as the accurate setup and configuration of spectrum analyzers. Its characteristics in anechoic chambers are well known, and the radiation plot can be used as a benchmark to compare the comb generator at the same location as the EUT with non-ideal settings. Using a rotary switch, you can select between five fixed comb frequencies and an external comb frequency input ranging from 5 kHz to 200 MHz. The switchable RF amplifier can potentially increase the output signal by 20 decibels (dB). The comb generator comes with two monopole antennas: one is a 30 cm monopole for frequencies up to 300 to 500 MHz, and the other is for frequencies above that. The radiated comb spectrum is characterized in the range of 5 MHz to 6 GHz.
A useful tool for verifying the correct operation of LISN, the proper setup of the spectrum analyzer, and the correct configuration.
The TBCG3-CN comb generator is primarily designed to verify the setup of conductive emission tests. It is a useful tool for validating the correct operation of the LISN, the proper setup of the spectrum analyzer, and the correct configuration. Using a rotary switch, you can select between five fixed comb frequencies and an external excitation input in the frequency range of 5 kHz to 300 MHz. The comb generator comes with country-specific adapter cables that plug into the DUT socket of the LISN (when powered off). This device operates on four AA nickel-metal hydride batteries and includes an external charger. The TBCG3-CN generates a comb spectrum with approximately 8 dB flatness over a frequency range of up to 1.5 GHz and features a 50-ohm output with a female N connector. The housing is made from solid aluminum, and the 1/4 inch – 20 UNC screws on the comb panel are compatible with standard tripod bolts.
Characteristic frequency range: 5MHz to 6GHz
The TBCG3-RN6 comb generator is primarily designed for testing radiated emission settings. It serves as a tool to verify the proper operation of antennas and preamps, as well as the accurate setup and configuration of spectrum analyzers. Its characteristics are well-known in anechoic chambers, and the radiation plots can be used as a benchmark to compare the comb generator with the EUT in the same location under non-ideal settings. Using a rotary switch, you can select between five fixed comb frequencies and an external comb frequency input ranging from 5 kHz to 200 MHz. The comb generator comes with two monopole antennas: one 30 cm monopole for frequencies up to 300 to 500 MHz, and another for higher frequencies. The radiated comb spectrum is characterized in the range of 5 MHz to 6 GHz. The TBCG3-RN6 features a 50-ohm output with a female N connector. This device operates on six AA nickel-metal hydride batteries and includes an external charger.
A general-purpose harmonic comb generator with switchable fundamental frequencies of 20MHz, 10MHz, or 5MHz.
The TBCG4 is a versatile harmonic comb generator equipped with switchable fundamental frequencies of 20 MHz, 10 MHz, or 5 MHz. It generates a flat comb spectrum of up to 1 GHz. The comb generator is powered from a USB C socket on the rear panel. The TBCG4 is designed and characterized to function as a multipurpose lab tool for measuring cable resonance, shielding effects, filters, crosstalk, and EMC test setups. The comb generator is commonly used as a general-purpose source for wideband RF signals or fast-rising narrow pulses.
