Problems finding VisaComLib documentation

[JM_Factory]

Hello,

I have an old Excel VBA macro that uses the VisaComLib to read data from an oscilloscope and stores it in a spreadsheet. Since now I have a new oscilloscope I need to adapt the old macro code to work with the new oscilloscope.

I have looked into the help files provided by NI-VISA, but I couldn't find any reference to VisaComLib, the Internet has not helped either. I would like to know where I can find any reference documents about the VISA COM library.

Thanks.

Why do you need to adapt the old macro?

[JM_Factory]

Both oscilloscopes use different operational commands.

Then just change the commands that are being sent. There is no need to re-invent the wheel.

Hate to say to but NI have never supported VISA-COM. Install Keysight Io Libraries they have documentation on this.
