Comb generators, or harmonic comb generators, are used in EMC emissions testing. ATEC offers comb generators capable of generating a wide frequency range, from leading manufacturers such as
ETS-Lindgren and
Com-Power.
A comb generator emits multiple, harmonically-connected CW signals spaced out over an oscillating frequency. Due to the consistency of the harmonic amplitudes, they are used to calibrate frequency and amplitude, providing a reliable baseline for measuring how well a system is working. Comb generators are used in electromagnetic interference and radio frequency interference testing to simulate the RF emissions of devices, especially consumer electronics.
When performing compliance testing for standards such as
MIL-STD-461, FDA, FAA, and FCC, comb generators are placed in semi-anechoic test chambers to isolate their signals. This allows technicians to determine which signals are coming from the DUT, and which are the generator's.
ATEC carries a variety of comb generators for rental, in stock and available for immediate shipping. Reach out for a quote today.
