【经验】如何使用是德科技精密LCR测试仪E4980A系列进行变压器测试
是德科技KEYSIGHT(原安捷伦Agilent)E4980A系列精密LCR测试仪拥有超高的性能和精度,是全球电桥产品的领导者,广泛应用于各大电容、电感、电阻厂家的生产检测和研发测试,也非常合适电子研发工程师进行PCB板上器件的测试。E4980A系列精密LCR测试仪使用不同的夹具,可以非常简单的完成各种封装形式的电容、电感、电阻的测试,比如镊子夹具16334A就是来料工程师用得最多的夹具,可以轻松的夹住各种贴片元件。如果需要超高的精度,这时就可以使用是德科技最稳定的贴片夹具16034E和引线夹具16047E,因为这个系列的夹具没有线缆的连接和损耗,是直接卡到E4980A系列精密LCR测试仪上的。
但是变压器有4根引线,就不能使用上述器件测试的夹具了,需要使用16060A变压器测试夹具,结合BNC同轴线和外部开关进行测试,或者使用自己制作的夹具也行,结构图如下:
测量前准备:使用Deviation 功能和Open/Short 校正,使用Deviation 功能,来进行Ls – Rdc的测量
1.把Hpot 端的开关打到“a”处(使用同轴开关)
2.把所有与A,B和common端连接的电缆进行短路
3.设置测量参数为Ls –Rdc 并测量 REF A, B的值
Open/short 校正,来进行互感 M 的测量
1.把Hpot 端的开关打到“b”处(使用同轴开关)
2.连接 A 和B 端, 并连接COMMON端
3.进行open校正操作
4.把所有与A,B和common端连接的电缆进行短路
5.进行short校正操作
测量主线圈的Ls – Rdc
1.将Open/short 校正关闭 (设置为 OFF)
2.测量参数设置为Ls - Rdc, DEV A, B 设置为 ABS
3.把Hpot 端的开关打到“a”处(使用同轴开关)
4.16060A的 A:B 设置为 N:1
5.测量Ls, Rdc
测量次级线圈的Ls – Rdc
1.将Open/short 校正关闭 (设置为 OFF)
2.测量参数设置为Ls - Rdc, DEV A, B 设置为 ABS
3.把Hpot 端的开关打到“a”处(使用同轴开关)
4.16060A的 A:B 设置为 N:1
5.测量Ls, Rdc
测量匝数比N
1.将Open/short 校正关闭 (设置为OFF)
2.测量参数设置为Ls - Rdc, and DEV A, B are set to ABS
3.把Hpot 端的开关打到“a”处(使用同轴开关)
4.16060A的 A:B 设置为 N:1
5.测量 VAC (this value is V1)
6.把Hpot 端的开关打到“b”处(使用同轴开关)
7.测量 VAC (this value is V2)
8.N 可以从 V1/V2的计算得到
测量互感系数M
1.将Open/short 校正打开 (设置为ON)
2.测量参数设置为Ls – Rs。 DEV A, B 设为 OFF
3.把Hpot 端的开关打到“b”处(使用同轴开关)
4.16060A的 A:B 设置为 N:1
5.测量Ls (此时的 Ls 就是 M)

【经验】如何使用LCR测试仪进行高精度电阻测试
如果要测试电阻小于1mΩ,万用表不行,微欧表不太好找的情况下,一般研发部门应该都有一台LCR测试仪,LCR测试仪顾名思义测试电容,电感,电阻的仪器。今天使用原安捷伦科技(已经改名是德科技Keysight)4263B来测试豪欧姆级别的电阻。
【经验】选择是德科技的E4980A LCR测试仪为什么必须选001选件
是德科技(Keysight)E4980A是一款高性能LCR测试仪,测试频率20Hz-2MHz,想要更加全面精确的测试电容,特别是低阻抗的大电容,就需要选择更高性能的E4980A LCR测试仪,并且选购001选件。
是德科技材料介电常数的七大测试方法
今天特别介绍是德科技 Keysight 材料介电常数测试方法。在选择最适合的测量方法时,必须考虑到多个重要因素,例如精度、方便性,以及材料的外形和形态。
