【经验】使用E4980AL高精度LCR测试仪如何选择Ls和Lp
某客户需要测试1MHz频率的电感,电感值大约40nH,阻抗约200m欧姆,电感非常的小,阻抗也非常的小。是德科技高精度LCR测试仪E4980A系列提供了大量详细的测试参数选择,便于为客户提供更高精度的测试结果,但是如何设置,也给客户造成了困扰。本文就来介绍使用E4980AL高精度LCR测试仪如何选择Ls和Lp。
Cp用并联等效电路模型测量的电容值
Cs用串联等效电路模型测量的电容值
Lp用并联等效电路模型测量的电感值
Ls用串联等效电路模型测量的电感值
D耗散因子
Q质量因子(D的倒数)
G用并联等效电路模型测量的等效并联电导
Rp用并联等效电路模型测量的等效并联电阻
Rs用串联等效电路模型测量的等效串联电阻
Rdc直流电阻
R电阻
X电抗
Z阻抗
Y导纳
qd阻抗/导纳的相位角(度)
qr阻抗/导纳的相位角(弧度)
B电纳
Vdc直流电压
Idc直流电。
使用是德科技高精度LCR测试仪E4980A系列测试电感时,我们会有两种选择,Lp用并联等效电路模型测量的电感值,Ls用串联等效电路模型测量的电感值。该如何选择测试参数呢?这个就比较让人为难了。我们来看看等效电路图,相同的设定频率下,大电感的电抗相对较大(电抗=2πfL),并联电阻比串联电阻更重要。因此,并联等效电路模式(Lp-D、Lp-Q或Lp-G)更为合适。相反,对于小的电感值,电抗变得相对较小,所以串联电阻更重要。因此,串联等效电路模式(Ls-D或Ls-Q)更合适。
因此,测试1MHz频率的电感,电感值大约30nH,阻抗约200m欧姆,阻抗比较小,我们可以选择Ls串联模式,E4980AL系列支持两种参数同时显示和测量,我们可以根据需要选择Ls和Rs,Ls和Rdc,Ls和Q,Ls和D等等,我们需要测试阻抗+电感,选择Ls和Rs,测试结果如下。一般来说,阻抗小于10Ω建议使用串联模式Ls,阻抗大于10kΩ建议使用并联模式Lp,两种中间值的差别不大。
