Referencing the IO Library
No matter which instrument programming library you use (SICL, VISA, or VISA
COM), you must reference the library from your program.
In C/C++, you must tell the compiler where to find the include and library files (see
the Keysight IO Libraries Suite documentation for more information).
To reference the Keysight VISA COM library in Visual Basic for Applications (VBA,
which comes with Microsoft Office products like Excel):
1 Choose Tools > References... from the main menu.
2 In the References dialog, check the "VISA COM 5.5 Type Library".
3 Click OK.
