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 take advantage of 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.
What is Lua?
Lua is a programming language that can be used with TSP-enabled instruments. Lua is an efficient
language with simple syntax that is easy to learn.
Lua is also a scripting language, which means that scripts are compiled and run when they are sent to
the instrument. You do not compile them before sending them to the instrument.
Lua basics
This section contains the basics about the Lua programming language to allow you to start adding
Lua programming commands to your scripts quickly.
For more information about Lua, see the Lua website (lua.org). Another source of useful information
is the Lua users group (lua-users.org), created for and by users of Lua programming language.
