摘要: 4110(相敏检波器)与4114(相控器)是美国 Evans 公司生产的两种集成线路板。按其本身的性能规定,由它们组成的锁定放大器(Lock-in Amplifier)一般只适合于在某固定频率附近(f_0±33%)工作。我们加以改进,制成一种适于宽广频率范围(0.2Hz～40kHz)又便于操作的 A 型锁定放大器。将它用于铁在酸中的腐蚀体系,表明它适用于腐蚀电极阻抗谱的测量。

Abstract：Model 4110(phase sensitive detector)and 4114(phase control unit)are integrated circuit modules(Evans Associates,Berkeley,CA,U.S.A.) which can be coupled to form a lock-in amplifier originally designed for use at narrow frequency ranges(±33% around the chosen central frequency f_0). We improved the modules and constructed the Model A lock-in amplifier useful for a wide band of frequencies(0.2 Hz to 40K Hz).The Model A lock-in amplifier has been applied to corrosion systems Fe/acid and proved satisfaetory for impedance spectra measurements of these systems.
