大部分元件需要DIY,所以需要知道元件的参数。因为DIY的元件没有标称技术参数。比如,需要知道谐振器件、检波器件、天线、耳机、变压器等器件的电抗特性。其中,高频参数可以使用Q表解决问题,而低频参数Q表难以测定。为了解决这个问题,笔者认为LCR数字电桥能够胜任。
设计目标:
1、能够准确测量电抗器的L、C、R,精度优于0.5 ,如果进行人工逐档校准,精度优于0.3
2、取材容易,电路简洁,易于制作,成本应适当控制。使之具有更强的业余DIY价值及研究价值,并通过设计、DIY学习到LCR电桥的相关细节、原理。
本LCR表的基本特性
AD转换器的字数:约1000字,采用了过采样技术,有效分辨力约为2000字
测量方法:准桥式测定,测量原理类似于比例法测电阻。
主要测量范围:1欧至0.5兆欧,精度0.5 (理论),阻抗实测比对,均未超过0.3
有效测量范围:2毫欧至10兆欧,最小分辨力1毫欧
串联残余误差:2毫欧,低阻测量时此误差不可忽略
并联残余误差:50M欧,高阻测量时此误差不可忽略
Q值误差:±0.003(Q<0.5),Q/300(Q>2,相对误差,简易算法),其它按0.5 左右估算
D值误差:±0.003(D<0.5),D/300(D>2,相对误差,简易算法),其它按0.5 左右估算
注意:Q = 1/D-Most components require DIY, so you need to know the parameters element. DIY components because there is no nominal technical parameters. For example, the need to know the reactance characteristic resonant devices, detection devices, antenna, headphones, transformers and other devices. Among them, high-frequency parameters can use Q table to solve the problem, while difficult to measure low frequency parameter Q table. To solve this problem, I think LCR digital bridge capable.
Design goals:
1, it is possible to accurately measure the reactor L, C, R, precision better than 0.5 , if the file manually by calibration accuracy of better than 0.3
2, drawing easy circuit is simple, easy to make, cost should be properly controlled. So that it has more value and amateur DIY research value, and learn details about LCR bridge, the principle by design, DIY.
The basic features of the LCR table
AD converter Word Count: approximately 1000 words, using the oversampling technology, effective reso
