我们提出了一种覆盖 100 kHz 至 190 MHz 频率范围的多功能射频外差光谱仪的设计，该光谱仪在整个范围内可用于核磁共振和声学实验。尽可能使用商业仪器：构建并详细描述了两个单元、一个射频脉冲发生器和一个 30 MHz IF 放大器/检测器。此外，我们还简要概述了超声波和核磁共振测量的应用以及与基于小型计算机的数据处理系统的接口。
We present the design of a versatile rf heterodyne spectrometer covering a 100 kHz to 190 MHz frequency range, which has been useful in nuclear magnetic resonance and acoustic experiments over its whole range. Commercial instruments were used wherever possible: two units, an rf pulse generator, and a 30‐MHz IF amplifier/detector were constructed and are described in detail. Also, we briefly outline application to ultrasound and NMR measurements and interfacing to a minicomputer‐based data processing system.
