The Com-Power CGO-520 Comb Generator is a conducted and radiated signal reference source. The signal contains frequency harmonics at 20 MHz intervals. These reference signals are used for validating EMC test sites; therefore the reference signal source must have a stable and precise output. Com-Power’s Comb Generators line is designed to meet this requirement. Due to the broad frequency range, two antennas are supplied with the CGO-520, a 12” antenna for low frequency up to 450 MHz, and 2” antenna for 450 MHz and above. The radiated signals are generated by connecting one of the two antennas to the BNC connector located at the center of the CGO-520. The circular chassis of Comb Generator helps radiate the signal more uniformly in all directions within the same plane. The conducted reference signals can be obtained by connecting a Coaxial Cable between the SMA connector mentioned above and a Spectrum Analyzer. The CGO-520 is powered by an enclosed rechargeable battery pack to minimize disturbances of external cables that might interfere with the radiated signal. When the battery voltage reaches below the operating level, the output signal will shut off automatically to prevent further use and misleading data. When fully charged, the battery allows continuous use of the Comb Generator for up to 18 hours. Batteries, charger and antennas are included.
