今天和群友聊到购置LCR,突然想知道低频LCR这边的业界最强精度是怎样的,遂开贴收集资料。

首先登场的是@Maaaaark001提到的IET公司的1693 RLC Digibridge:

UJ }0OG9`Y7SY~B0)G)$0M9

号称是标准级的仪器。

具体指标如下:

X8MBV~M{H6081C{Q6UXGRIQ

然后在搜索中我发现Keysight貌似不服,拉出了自家的E4980AL Precision LCR Meter 和1693决战:

4U@SNP52VH1_$F8X8C4JYS9

看上去确实是Keysight更强。

然后是@Maaaaark001提到的ANDEEN-HAGERLING的专攻电容测量的AH 2700A:

此外,日置的电桥似乎也很强,相关信息有待补充。

似乎可以开个Precision Meter Collection,收集一些各个领域的顶级仪器仪表,不过这样的话似乎HP/Keysight要霸榜了(
