Low Frequency Amplifiers

Low frequency, or DC, RF amplifiers are high-power audio amplifiers for EMC testing. These devices have frequency ranges starting below 10 kHz and are particularly notable for their low output impedance. They are used when slow-changing or weak signals are required to test automotive or aerospace devices according to IEC 61000-4-8 (magnetic field testing), IEC 61000-4-16 (conducted, common-mode disturbances in a low frequency range), and MIL-STD-461 CS101 (power leads). ATEC has low frequency amplifiers in stock and available for rental from manufacturers such as AE Techron and BOLAB Systems.
