PROGRAMMING SEQUENCE
The EX10xxA instrument driver is a VXI plug&play driver that is composed of top-level
C functions. The Figure 6-1 describes the typical steps performed in programming an acquisition
sequence on the EX10xxA. While the flow chart implies an order dependence to the functions, none
truly exists. Each function operates in a disjoint manner. The flow chart, however, does present a
logical flow of operations. For many applications, some of the detailed steps would not be required,
either because the default parameters are sufficient or the associated functionality is simply not
required.
