中文摘要:
      提出了一种基于虚拟仪器技术的阻抗分析仪设计方法,采用自动平衡电桥阻抗测量法开发了一台阻抗分析仪。该阻抗分析仪利用信号发生卡输出电压激励信号、采用高速数据采集卡进行两通道电压同步采集、以labVIEW为平台开发测控软件实现仪器板卡控制、阻抗测量以及数据分析和处理。测试结果显示:在频率20 Hz~500 kHz、阻抗1 Ω~500 kΩ范围内,该阻抗分析仪测量误差小于5%;其频率扫描点数、测量结果的显示和保存方式可通过软件进行灵活配置。基于虚拟仪器技术的阻抗分析仪通用性和扩展性强、测试范围广、操作简单便捷。根据实际的测量需求可灵活选择不同性能指标的信号发生卡、数据采集卡以及阻抗测量电路元件参数,开发成本可控且开发周期短,可广泛应用于科研和教学实验室仪器的开发。
英文摘要:
      It was proposed to design an impedance analyzer based on the virtual instrument technique and an impedance analyzer was developed utilizing the automatic balance bridge impedance measurement method. A signal generating card and data acquisition card were selected to provide the exciting voltage signal and acquire the two voltage signals simultaneously with a high sampling rate, respectively. A measuring and controlling software was developed with LabVIEW to control the instruments, measure the impedance and analyze the data. It has been demonstrated through the tests that: the measurement error of impedance is below 5% with the frequency ranging from 20 Hz to 500 kHz and the impedance ranging from 1 Ω to 500 kΩ; the frequency scanning points, displaying and saving of the measurement results can be configured flexibly and conveniently through the software. The impedance analyzer developed based on the virtual instrument technique can be used in more general applications and has a wider measurement range. It can be operated more conveniently and the function can be extended and reconfigured more easily. Furthermore, the performance can be upgraded or degraded through an appropriate selection of the signal generating and data acquisition cards and parameters of the measurement circuit according to the real requirements. The development cost is controllable and the required time is short. Therefore, the design approach for an impedance analyzer is well applicable to the development of instruments in the scientific research and teaching laboratories.
