C++ Example 

 

Background 

The following program creates a connection to 
the 2260B and sets the voltage to 3.3 volts and 
the current 1.5 amps. The voltage and current 
reading is then read back and the connection is 
closed.  

 Note 

Add visa32.lib to the project library when 
building the following sample program.
