Comb Generator Reference: 100 MHz Step Size

A broadband EMC Reference signal source Com-Power Model CGO-5100B Comb Generator is for quick EMC site testing. It radiates signals up to 18 GHz at 100 MHz 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 antennas, etc. For example, as the frequency increases a 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. The CGO-5100B is powered by a rechargeable NimH battery pack. It has a circular shape for a uniform radiated output.
