Fundamentals of programming for TSP
To conduct a test, a computer (controller) is programmed to send sequences of commands to an
instrument. The controller orchestrates the actions of the instrumentation. The controller is typically
programmed to request measurement results from the instrumentation and make test sequence
decisions based on those measurements.
To use the advanced features of the instrument, you can add programming commands to your scripts.
Programming commands control script execution and provide tools such as variables, functions,
branching, and loop control.
The Test Script Processor (TSP
®
) scripting engine is a Lua interpreter. In TSP-enabled instruments,
the Lua programming language has been extended with Keithley-specific instrument
control commands.
