摘要：

The authors present the design and fabrication details of a phase-sensitive radio-frequency superheterodyne ultrasonic spectrometer. They also present results of measurements to test the operation of the spectrometer. The spectrometer allows simultaneous measurements of both velocity and attenuation over a wide frequency range with little adjustment. It has been built mainly using commonly available RF circuit components.
