数字电桥就是能够测量电感，电容，电阻，阻抗的仪器，这是一个传统习惯的说法，阻抗测量用的是真正的电桥方法，随着现代模拟和数字技术的发展，早已经淘汰了这种测量方法，但LCR电桥的叫法一直沿用至今。如果是使用了微处理器的LCR电桥 Digital bridge is an instrument that can measure inductance, capacitance, resistance and impedance. This is a traditional saying. The earliest impedance measurement used is a real bridge method. If it is using a microprocessor LCR bridge
