Comb Generator 1 and 5 MHz Stepsize Com-Power CG-515

I Introducing Com-Power CG-515:

Used as an artifact for the Automotive EMC Laboratory Identification Program (AEMCLRP), the CG-515 Comb Generator is a broadband EMC signal source for rapid EMC site testing. EMC laboratories calibrate radiated emissions testing sites, instruments, and accessories at least once a year. Calibration procedures are complex and time consuming. However, calibration does not prevent equipment malfunctions mid-calibration such as broken receivers, broken cables, poor connections, bad antennas, etc. Regular monitoring of several frequencies on the Comb Generator’s broadband radiated output can verify the entire setup quickly and effectively. Any potential problem in the test setup can be detected before it causes erroneous results. It is powered by a rechargeable NimH battery pack.
