不同厂牌的校准件及矢网如何相互使用

[{"insert":"校准件及仪表互通用的问题一直存在，经常有人可能出于成本的考量，需要使用非原厂的校准件去校准某些其它品牌的网分，通常仪表厂商都会将自己公司的所有型号校准器的参数内建在仪表里，但是对于其它品牌的校准器一般不会内置，不过笔者发现有些国产品牌的网分会有内置Keysight的校准器参数。今天就跟大家分享一下具体怎么去手动输入校准件的参数来操作。\n \n"},{"attributes":{"bold":true},"insert":"1-->如何使用安立的校准件去校准是德的网分"},{"insert":"\n"},{"attributes":{"bold":true},"insert":"2-->如何使用是德的校准件去校准安立的网分"},{"insert":"\n仅以上述两种方式作为代表，供大家学习分享，希望能有所帮助。\n \n"},{"attributes":{"bold":true},"insert":"1-->如何使用安立的校准件去校准是德的网分"},{"insert":"\n \n以Keysight的E5063A为例，点击操作面板的【Cal】按键会进入校准菜单，默认的校准器型号是85033E。\n "},{"insert":{"image":"https://community-1252773949.cos.ap-guangzhou.myqcloud.com/article/2032/031e117b2515a40c.png"}},{"attributes":{"align":"center"},"insert":"\n"},{"insert":"点击【Cal
