Load Instrument State 
Load (open) a previously-saved instrument state file (*.acpwps).
To open the instrument state, click 
> Open Settings. Then select the state file to load and click Open.
- By default, the instrument state is stored in the "Documents" folder on your computer and files are organized by instrument type. For example – C:\Users\<user_name>\Documents\Keysight\PathWaveACSource\.
- Within the AC Source application, instrument state files are stored with an *.acpwps file extension. An error message will be displayed if an invalid or corrupted file is loaded.
- To successfully recall a stored state, the instrument model number must match the instrument running at the time of the save operation. If the instrument is not connected or is no longer available at the time of the recall operation, an error will be generated.
