你好,SYSTem:INTerface {GPIB | RS232}我想知道,这个命令的确切用法是什么?
我认为它将远程通信类型设置为RS-232(如果之前(手动)设置为GPIB并且相反。 但显然它不起作用,因为只能为那些设置为设备的类型打开连接(手动与否,无关紧要)。 打开后,它不允许您通过软件更改此通信类型。 请参见附图(来自Command Expert)。 我想它必须有一些其他意义,而不是我想的那个。 有人可以解释一下吗? 谢谢。 以上来自于谷歌翻译 以下为原文 Hello, SYSTem:INTerface {GPIB|RS232} I would like to know, what is the exact usage of this command? I thought that it sets the remote communication type to RS-232 if it was previously (manually) set to GPIB and inversely. But obviously it is not working, since the connection can only be opened for that type that is ALREADY set to the device (manually or not, it does not matter). And after being opened, it does not let you change this communication type by software. See the attached picture (from Command Expert). I guess it must have then some other significance than the one I thought. Can somebody explain me this? Thanks. 附件

我认为你的解释是正确的。
这是一个非常无用的命令。 如果使用它切换界面,则必须先使用新选择的界面连接仪器,然后才能再次与仪器通信。 说明此命令/查询选择仪器的远程接口。 一次只能启用一个接口。 仪器出厂时选择GPIB接口。 备注•该命令仅对34970A有效。 34972A将接受该命令,但该命令将不起作用。 参数和对查询的响应都没有意义。 •立即禁用未选择的界面*。 以上来自于谷歌翻译 以下为原文 I think your interpretation is correct. It is a pretty useless command. If you switch the interface with it, you would have to connect to the instrument with the new selected interface before you could talk to the instrument again. Description This command/query selects the remote interface for the instrument. Only one interface can be enabled at a time. The GPIB interface is selected when the instrument is shipped from the factory. Remarks • This command only has effect on the 34970A. The 34972A will accept the command, but the command will have no effect. Both the parameters and the response to the query are meaningless. • The non-selected interface is *disabled immediately*. |
