retrieve header and library files?

Hi, 

 

I have an issue on the GPIB connection for my new power supplies (Keysight N8700A series).

 

Previously was using old model of power supplies which is obsolete, thus these series of power supplies is the new replacement. 

 

I have Keysight IO library which is able to detect and connect my existing power supply, I can retrieve my header and library file in keysight folder in my PC but when I change to new power supply, I cannot see any header nor library files. 

 

I need these files for my Labwindow CVI programming

Anyway to get the files from the folder ?

These Keysight instruments accept SCPI commands.  You should be able to get the instrument information by sending the ID query string:

*IDN?\n

Not sure what other information you are referring to in your post.

Hi, thank you first for your reply.

 

I need .h and .dll files for my C programming language for my system control.


Therefore, I just need to know where is the location of the .h and .dll files for my power supplies.

Either you need to make them or get them from Keysight.  Seeing how most of these instruments were previously running HP firmware or possibly upgraded to Agilent software, most of the calls should be the same for the .h files and possibly the .dll file as well.  They may require a slight modification or name change.

Hi, i have attached the image on the example of file location for .h and .dll (highlighted in yellow) for the old model of power supplies connected to Labwindow CVI. Yet after changing to new model of power supply, it is not longer able to find retrieve the files. 

Do you mean that we have to get all these files from Keysight software and it got nothing to do with NI software configuration?

hi, thank you.

I managed to find the file in the IVI driver path.

 

The location slightly changed from the previous location.

 

No modification needed to be done though.

Thank you again for your help!
