Test station: Spectrum operations and programming lvl 1

An introduction to the world of GR228X programming, with the emphasis placed on overall program development, analog models and TEST XPRESS tools. The TEST XPRESS suite of tools will be explained and used as part of the test development process, generation and debug. Generation of reports to be sent to vendors for design and construction of test fixtures and determining the acceptability of these fixtures, as well as, test programs developed by contract programmers. Detailed exercises on the modification of existing programs to reflect changes on the board. These changes include components, values and tolerances.
