Hi Angela,
The program you're looking for is MAX (Measurement and Automation Explorer). MAX is a separate tool and it's not icluded in LV. MAX is the tool for configuring and testing NI boards. Just select your board in MAX and open the Test Panel. You can then test the functionality of the board.
Another, easier option is to use the "E Series Diagnostic utility" which you find here: http://www.ni.com/support/selftest/
This tool test the whole functionality automatically for E-Series boards.
Hope this helps.
Regards,
Luca
