Run-time and nonvolatile memory storage of scripts

Scripts are loaded into the run-time environment of the instrument. From there, they can be stored in
the nonvolatile memory.
The run-time environment is a collection of global variables, which include scripts, that the user has
defined. A global variable can be used to store a value while the instrument is turned on. When you
create a script, the instrument creates a global variable with the same name so that you can
reference the script more conveniently. After scripts are loaded into the run-time environment, you
can run and manage them from the front panel of the instrument or from a computer. Information in
the run-time environment is lost when the instrument is turned off.
Nonvolatile memory is where information is stored even when the instrument is turned off. Save
scripts to nonvolatile memory to save them even if the power is cycled. The scripts that are in
nonvolatile memory are loaded into the run-time environment when the instrument is turned on.
Scripts are placed in the run-time environment at the following times:
•
When they are run.
•
When they are loaded over a remote command interface.
•
When the instrument is turned on (if they are stored in nonvolatile memory).
For detail on the amount of available memory, see
environment
If you make changes to a script in the run-time environment, the changes are lost when the
instrument is turned off. To save the changes, you must save them to nonvolatile memory. See
Saving a script to nonvolatile memory

What can be included in scripts?

Scripts can include combinations of TSP commands and Lua code. TSP commands instruct the
instrument to do one thing and are described in the command reference (see
page 8-7)). Lua is a scripting language that is described in
page 7-11).

Working with scripts

This section describes the basics of working with scripts.
You can create and manage scripts from the front panel or over a remote interface. Scripts can be
saved in the instrument, on a computer, or on a USB flash drive.
