visa写入错误

[yanzhongsan]

各位好：

最近碰到一个很头疼的问题，写入VISA时时不时报错：

 

请问这是什么原因造成的？多谢各位。

别用 VISA 。

VISA 报错时，常常信息不全。

Aglient 的仪器一般都有 GPIB 的 llb 。

GPIB的LLB？请问0哪里下载呢？NI还是Agilent? 这个问题困扰了我很久，还是没有解决。

另外我现在需要控制的仪器有的很老，都找不到驱动，这种情况下只能直接调用VISA写入来做？还是能有别的方法？直接调用GPIB写入函数？这个很会报错，时不时说中断号没注册……

(This is assuming that you are using NI's GPIB controller card)

You may try searching for the instrument's drivers at IDNET

If driver is not found for your device, you may have to refer to/ request for a copy of its programming manual which usually provide the SCPI commands set.
