Com-Power CGO-501 Comb Generator is a broadband EMC signal source for quick EMC site testing. It radiate signals up to 1000 MHz with a 1 MHz step size. EMC labs calibrate their radiated emissions test sites, instrumentation and accessories at least once a year. The calibration procedures are elaborate and time consuming. However, calibration does not prevent equipment malfunction in between calibration period such as damaged receivers, broken cables, poor connections, bad antenna, etc. Monitoring a few frequencies regularly on the Comb Generator's broadband adiated output can verify the entire setup quickly and efficiently. Any potential problems with the test setup can be detected before it causes erroneous results. It is powered by a rechargeable NimH battery pack. It has circular shape for more uniform radiated output.

  • Frequency range of 1 MHz to 1 GHz
  • Stable Frequency Output
  • Automatic Low Voltage Signal Shutoff
  • Battery Operated
  • Three-Year Warranty

Comb Generator is reference radiated or conducted signal source. The signal contains frequency harmonics at 1,5, 20 MHz intervals. These reference signals are used for validating EMC test sites. A reference signal source must have stable and precise output. Therefore, Comb Generator?s internal circuit is built to meet this requirement. Two antenna supplied with the Comb Generator for low and high frequency signal radiation.The radiated signals are generated by connecting one of the two antennas to the BNC or SMA connector. The circular chassis of Comb Generator helps radiate the signl more uniformly in all directions in the same plane. The conducted reference signals can be obtained by connecting a coax to the BNC or SMA connector. The Comb Generator is powered by a rechargeable internal battery pack to eliminate any possibility of external cables effecting the radiated signal. When the battery voltage reaches below reliable operating levels the RF will shut off automatically to prevent further use. When fully charged, the battery allows continuous use of the Comb Geneator up to 18 hours. The Comb Generator, charger and antennas are shipped in a custom wooden storage box.
The CGC series Comb Generator was specifically designed to test installed Line Impedance Stabilization Networks (LISNs). LISNs are used for EMC conducted emissions testing according to FCC Part 15, CISPR, and EN requirements. The Comb Generator output is connected to the LISN EUT power port and measurements are taken similar to an EUT. For convenience, the CGC series Comb Generators have 3 prong standard US plug for LISNs with matching EUT power socket. By using the Comb Generator the test engineer can quickly identify any problems with the conducted setup before making any measurements with an EUT.
