A new testing requirement for some of my company's products is IEC 61000-4-16 Conducted Common Mode Disturbances. I need to test from 10 kHz to 150 kHz.
I have a good low distortion signal source, but I need a power amplifier to give me the signal at the test level: 30 Vrms open circuit, 50±5 ohms source impedance, total harmonic distortion below 1%. While this sounds like something not far beyond the capability of a good audio amplifier (with a series 50 ohm resistor at the output), it is proving rather difficult to find such an amplifier. Amplifier Research and Techron both have amplifiers that are close but not quite there (either voltage swing or distortion). I can buy complete solutions from EM Test, Frankonia, EMC Partner, and HV Technologies. But I believe that there must be a power amplifier out there that can do the job. Ideas anyone?
