Comb Generator with output to 40 GHz

Model CGO-51000 Comb Generators is a broadband EMC signal reference source for quick EMC site testing. It radiates signals up to 40 GHz at 1 GHz frequency steps. 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. For example, as the frequency increases poorly mated connector can cause significant measurement errors. 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. It is powered by a rechargeable NimH battery pack. It has circular shape for more uniform radiated output.
