Controls: Generator Dialog >> Load Setup
Macro: LoadGEN

This option is available from the button near the bottom of the main Generator dialog or from the File menu ( ALT+F, L).

You can activate this at any time to change the setup to one you have previously saved. The default file name is '*.GEN', so if you click on this button you will see all the setups you can choose from in the default directory.

A setup includes the names of any Arb and/or Play files it uses, and when you load the setup, those files are loaded as well. But if those files are no longer present or have errors, the load process will report this and prompt you for confirmation. You can't abort the load at this point, since things would be left with an unstable partial setup. You just have to hit a key to confirm the error, and when the setup is done loading, any problem files will be missing. If any had been selected to be active on any stream of the setup, that stream will have Sine selected instead.

Note that when you initially load Arb/Play files you can load from an arbitrary directory instead of the default Daqarta data directory. The path for each file will be saved with the setup. Thus, you must make sure you don't delete, move, or rename any Arb or Play files that you are using for a setup. Also, if you want to run the same setup on another system, you must make sure all these files are in the same directories on the other system.

Since the setup file only saves signal settings, and not the main sample rate, it is possible to load a setup that was saved while running with a different sample rate than is currently in use. In this case, all Generator frequencies are adjusted automatically to give the same values with the current sample rate. However, there is no automatic adjustment for durations, such as Burst or Sweep, which are stored in the setup as numbers of samples. You may need to adjust those manually, depending upon the desired result.

Macro Notes:

The LoadGEN macro has no effect if any File Open or Save As dialog is already active.

LoadGEN= without a name will pop up the File Open dialog showing all GEN files, but with no default name.

LoadGEN="MyFile" will pop up the File Open dialog with the default name set to MyFile. (Note that quotes are needed around all filenames in macros.) If you accept this by hitting Enter or the Open button in that dialog, Daqarta will assume you want to open a file named MyFile.GEN and will fail if that file is not found.

A.LoadGEN="MyFile" will open MyFile.GEN directly, without any File Open dialog. Note that this will load the specified setup without saving changes to the existing setup, if any.

LoadGEN=">Field1" will use the contents of Field1 as the default file name, and A.LoadGEN=">Field1" will use that name directly.
