Keysight Caught Unexpected Error

Technical
1

Hi everyone,

We are using the Keysight KS8400 9.26.1 Editor, and we are getting a DllNotFoundException (As seen below). Although it does not block the execution, we are worried if it may cause any other issues. We do not face this on other PCs, however we tried cleaning and reinstalling the editor, as well as our instrument drivers but we still get the exception.

We usually face it when opening with an instrument resource e.g. Keysight signal generator 33612A. Could there be a possibility of a driver conflict? Wondering if anyone had an initial idea or advise on how to troubleshoot. Thanks in advance!

Hi @antonio.quizon,

It looks like you are using a different visa base class than OpenTAP ScpiInstrument. This looks a bit like the .NET Visa wrapper.

Is there a reason why you went with that solution?

In any case, from the error message it seems like you are missing the visa32 DLL from Keysight. You can get that by installing Keysight IO Libraries: https://www.keysight.com/us/en/lib/software-detail/computer-software/io-libraries-suite-downloads-2175637.html
