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 are well-known in anechoic chambers, 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 range of 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 being a 30 cm monopole for frequencies up to 300 to 500 MHz, and the other 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. By 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 machined from a block. 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 preamplifiers, 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 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 300-500 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 comes with an external charger.
A general-purpose harmonic comb generator with switchable fundamental frequencies of 20MHz, 10MHz, or 5MHz.
The TBCG4 is a versatile high-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 the 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, EMC test setups, and more. The comb generator is commonly used as a general-purpose source for wideband RF signals or fast rise-time narrow pulses.
