如何使用VISA读取线执行操作？

嗨，我很抱歉，但我们不熟悉Keithley 237命令集。
我只是快速浏览一下，它绝对不是SCPI兼容的。
你在使用VISA或VISA-COM吗？

  Hi,

I'm sorry but we are not familiar with the Keithley 237 command set.  I just took a quick look and it is definitely not SCPI compatible. 

Are you using VISA or VISA-COM?

嗨马特，我相信我正在使用VISA COM。
这是代码：设置ioMgr =新的VisaComLib.ResourceManagerSet instrK237 =新的VisaComLib.FormattedIO488Set instrK237.IO = ioMgr.Open（“GPIB1 :: 17 :: INSTR”）.... instrK237.WriteString“N1X”'设置为OPERiSleep 1000instrK237
.WriteString“H0X”'TRIGGER SWEEPiSleep 50000'UGLY DELAY HERE，根据nA中的低电流测量而变化'如果我在发送下一个cinstrK237之前只能使用OPC查询，我可以在这里循环.WriteString“N0X”'OPER OFFiSleep 1000instrK237.WriteString
“X”iSleep 1000ar1 = CleanString（instrK237.ReadString（））'GETS数据arrayThanks和问候

  Hi Matt,

I believe Im using VISA COM. Here's the code:

Set ioMgr = New VisaComLib.ResourceManager
Set instrK237 = New VisaComLib.FormattedIO488

Set instrK237.IO = ioMgr.Open("GPIB1::17::INSTR")

....
instrK237.WriteString "N1X" 'Set to OPER
iSleep 1000
instrK237.WriteString "H0X" 'TRIGGER SWEEP
iSleep 50000                       'UGLY DELAY HERE, varies depending on low current meas in nA
                                         'I can loop here if I can only use the OPC query before sending next c
instrK237.WriteString "N0X" 'OPER OFF
iSleep 1000
instrK237.WriteString "X"   
iSleep 1000
ar1 = CleanString(instrK237.ReadString()) 'GETS data array

Thanks and regards

我理解，你想在VB 6.0中使用VISA-COM对SRQ进行串行轮询/异常处理吗？
如果是这样，我会看看我是否可以生成一个示例（它将基于安捷伦电源）并在此处发布。



     以下为原文

  Just so I understand, you want to do a serial poll/exception process for a SRQ using VISA-COM in VB 6.0?  If so I'll see if I can generate an example (it will be based on an Agilent power supply) and post it here.

嗨马特，只想知道VISA-COM的功能，如果它可以支持旧的PS。
只是想知道，因为它得到了HP Basic的支持，而且由于VISA-COM是“新的”，它应该是向后兼容的，我想。最好的问候，Bab

  Hi Matt,

Just want to know the capabilities of the VISA-COM if it can support the old PS. Just wondering since it was supported by HP Basic, and since VISA-COM is 'newer', it should be backward compatible, I guess.

best regards,
Bab

嗨马特，我刚用命令“U”来获得扫描的当前步骤。
感谢您的支持

  Hi Matt,

I just used the command "U" to get the current step on the sweep. Thanks for your support.
