EMI Source for CISPR and FCC Com-Power model CGO-501 Comb Generator is a broadband EMC signal source for quick EMC site testing. It radiates signals up to 1500 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 malfunctioning in between calibration periods, such as damaged receivers, broken cables, poor connections, bad antennas, etc.
Monitoring a few frequencies regularly on the Comb Generator's broadband radiated output can verify the entire setup quickly and efficiently.
Any potential problems with the test setup can be detected before it causes erroneous results.
A rechargeable NimH battery pack powers it. It has a circular shape for uniform radiated output.
