AB  - The paper presents a comparison of five configurations used to test intermodulation of ultrasonic signals. All five require the use of ultrasonic loudspeakers in an anechoic, low-noise environment. Settings vary in the number and type of digital-to-analog converters and loudspeakers, as well as connection types. Best configuration introducing a small amount of self-intermodulation for the high power of the ultrasonic signals is identified.
