Using the function

visadev('TCPIP0::127.0.0.1::inst0::INSTR')

Gives the error

无法获得签证f安装信息rom shared library.

And

visadevlist

returns

Unable to find any VISA resources during the specified timeout period. Open the vendor's control software to search for available

VISA resources.

I am also getting this error when connecting to Keysight instruments. It is particularly frustrating because there appears to be no change in the hardware or connectivity setup parameters. I didn't run into this issue using the original 'visa'

Hello,

I had the exact same problem and fixed it as follows:

Open your Keysight Connection Expert
In the top right hand corner, click the little gear symbol to open the settings dialogue
Go to "Tools"
Got to "VISA Conflict Manager"
In the tab "General VISA Settings", no implmentations were enabled when I first opened it. I have multiple implementations installed and now enabled "Keysight VISA" and "Keysight VISA.NET". Also, I selected them as the "Preferred Implementation".
Press "Apply" and "OK"

After this, the

visadev

command worked again for me.

I tried this and it was still the same error. Increasing the Timeout didnt help either. Any idea why this is?
