[问答] Keithley 237怎么与Agilent 82357A一起使用LabView
173 labview
分享
大家好。
我是LabvView编程的新手。
我制作了一个用labview控制我的Keithley 237的程序。
我使用Agilent 82357A来控制吉时利。
到目前为止,我还没有在与设备通信方面取得任何成功。
据我所知,我必须通过Agilent 82357A与我的吉时利设备进行通信的方式是VISA协议吗?
我能够让LabView和MAX检测到Agilent卡,现在我可以在LabView中使用我的Keithley的VISA地址。
但是,当我通过LabView中的VISA发送命令向Keithley发送典型命令(如复位或设置电压)时,我会收到一些错误。
如果你能以某种方式帮助我,我会感激不尽。
问候,路易斯。

  Hi everyobody. I am new with programming in LabvView. I have made a program to control my Keithley 237 with LabView. I use an Agilent 82357A to control the Keithley. So far I havent had any succes in communicating with the device. As far as I understand, the way I must communicate with my Keithley device through the Agilent 82357A is by a VISA protocol right? I am able to make that LabView and MAX detect the Agilent Card, and now the VISA Address from my Keithley is available to be used in the LabView. However, when I send the typical comands such as Reset, or Set Voltage to the Keithley through the VISA Send command in LabView I get back some errors.
I would beglad IF you could help me in some way.
Greetings,
Luis.

您好Luis,我不是Labview或Keithley 237的专家。您需要使用VISA协议进行通信,因此您需要打开VISA会话,然后使用VISA读写进行通信。
你能和MAX的Keithley 237进行交流吗?
您是否尝试过使用NI Spy来查看总线上发生了什么?
您是否安装了Agilent IO Libraries?
它可以与NI VISA并排安装。
我从未使用过带有NI VISA的82357。
这也可能有所帮助。
谢谢,马特

  Hi Luis,
I am not really an expert at Labview or the Keithley 237.  You do need to use the VISA protocol to communicate so you would need to open a VISA session and then use VISA reads and writes to communicate.   

Are you able to communicate with the Keithley 237 in MAX?  Have you tried using NI Spy to see what is going on over the bus?  

Do you have the Agilent IO Libraries installed?  It can be installed side by side with NI VISA.  I have never used my 82357 with NI VISA.  That might also help.

Thanks,

Matt

hi, Luis
if you have got the Agilent IO Libraries, you still need to set the VISA Confilict managnment on the setting, choose the NI VISA, then you can make programme on labview and control the device.
