How to Accurately Measure Higher-Order IMD Products Using a Spectrum Analyzer?

You see terrible intermodulation distortion1 (IMD) results on the screen, and they don’t match the datasheet. Is your expensive new amplifier a dud? It’s a frustrating and costly problem. To accurately measure IMD, you must use the spectrum analyzer’s internal attenuator. By increasing the input attenuation by 10 dB, check if the measured IMD products […]
