While you can implement parallel testing in most existing test systems, modular test system architectures deliver the best results when used in a parallel testing environment.
Test management software, such as NI TestStand, and modular PXI hardware
components offer many features for obtaining the highest performance out of a
parallel test system. However, you can implement parallel testing using much of
your existing test hardware without further hardware investment. Once you have
selected your test architecture, the next step is to select the best process
model based on your desired UUT test behavior.
