Section 6: Instrument programming
Create and load a script
You create scripts by loading them into the runtime environment of the instrument. You can load a
script as a named script or as the anonymous script.
Once a script is loaded into the instrument, you can execute it remotely or from the front panel.
Anonymous scripts
If a script is created with the loadscript or loadandrunscript command with no name defined,
it is called the anonymous script. There can only be one anonymous script in the runtime environment.
If another anonymous script is loaded into the runtime environment, it replaces the existing
anonymous script.
Named scripts
A named script is a script with a unique name. You can have as many named scripts as needed in the
instrument (within the limits of the memory available to the runtime environment). When a named
script is loaded into the runtime environment with the loadscript or loadandrunscript
commands, a global variable with the same name is created to reference the script.
Key points regarding named scripts:
•
If you load a new script with the same name as an existing script, the existing script becomes an
unnamed script, which in effect removes the existing script if there are no variables that
reference it.
•
Sending revised scripts with different names does not remove previously loaded scripts.
•
Named scripts can be saved to internal nonvolatile memory. Saving a named script to nonvolatile
memory allows the instrument to be turned off without losing the script. See
in nonvolatile memory
Load a script by sending commands over the remote interface
To load a script over the remote interface, you can use the loadscript, loadandrunscript, and
endscript commands.
The loadscript and loadandrunscript commands start the collection of messages that make
up the script. When the instrument receives either of these commands, it starts collecting all
subsequent messages. Without these commands, the instrument runs them immediately as individual
commands.
The endscript command tells the instrument to compile the collection of messages. It compiles the
messages into one group of commands. This group of commands is loaded into the runtime
environment.
