有没有办法查询ENA以确定哪个频道是活动的。
我想为用户通过前面板激活的通道获取跟踪数据,而不是以编程方式。 问题是我需要知道在读取格式化数据之前选择了哪个通道。 谢谢你的帮助。 小号 以上来自于谷歌翻译 以下为原文 Is there a way to query the ENA to determine what channel is active. I want to take trace data for a channel that has been activated by the user through the front panel, not programmatically. The issue is that I need to know which channel is selected before I read the formatted data. Thanks for your help. S |

您好,对于ENA不确定,但对于具有正确固件的PNA,您可以使用这些SCPI命令查找活动通道或测量:SYST:ACT:CHAN?
SYST:ACT:MEAS? 这在PNA帮助文件的“使用SCPI参考跟踪,测量,通道和Windows”部分中进行了描述。或者访问此Web链接:http://na.tm.agilent.com/pna/help/latest /Programming/Learning_about_GPIB/Referring_to_Traces_Measurements_Channels_Windows_Using_SCPI.htm希望有所帮助,rok 以上来自于谷歌翻译 以下为原文 Hello, Not sure for an ENA, but for a PNA with the right firmware, you can use these SCPI commands to find the active channel or measurement: SYST:ACT:CHAN? SYST:ACT:MEAS? This is described in the PNA help file under the section: 'Referring to Traces, Measurements, Channels, and Windows Using SCPI' Or go to this web link: http://na.tm.agilent.com/pna/help/latest/Programming/Learning_about_GPIB/Referring_to_Traces_Measurements_Channels_Windows_Using_SCPI.htm Hope that helps, rok |

您好,我认为这不会起作用,因为ENA不存在此命令(至少我在程序员指南中找不到它)。
试试:SERV:CHAN:ACT? 此命令的描述:读出活动通道编号(仅查询)请参阅程序员指南:http://cp.literature.agilent.com/litweb/pdf/E5070-90412.pdf#I16.5.3408369 以上来自于谷歌翻译 以下为原文 Hello, I don't think this will work as this command doesn't exist for the ENA (at least I couldn't find it in the programmers guide). Try :SERV:CHAN:ACT? Description to this command: Reads out the active channel number (Query only) See programmers guide: http://cp.literature.agilent.com/litweb/pdf/E5070-90412.pdf#I16.5.3408369 |
