These programming examples are implemented using MS Developer

 

 

Studio. Regardless of the programming environment you use, keep the

 

following in mind:

 

 

• The resultant application is a "console application"

 

 

• Make sure the header files visa.h and visatype.h are included.

 

 

• Make sure the library path includes visa32.lib

 

 

• Ensure that the PATH environment variable allows loading visa32.dll.

 

 

The programming examples do not cover the full command set for the

 

 

instruments. They are intended only as an introduction, how to program

 

the instrument using VISA library calls.

 

 

The VISA calls used, are explained in detail in the VISA User’s Guide.

 

 

Never use VISA calls and the Agilent 816x VXIplug&play Instrument Driver
