64 HP E1312A/E1412A Multimeter Application Information
HP VEE is HP's Visual Engineering Environment, a graphical programming
language for creating test systems and solving engineering problems. This
section provides an instrument control example using the "Direct I/O"
feature of HP VEE. Direct I/O allows you to directly specify messages to be
sent to an instrument and to directly read the information sent back by an
instrument. Direct I/O also offers the most efficient I/O performance in
HP VEE.
The example provided here synchronizes a measurement scan with a switch
module. This is the same example previously discussed in this chapter with
programs provided in the C and Visual Basic programming languages.
You must configure your HP E1312A or HP E1412A Multimeter (and the
switch module) before you can communicate with them.
