SpecMan4EPR Help: Experiment Axis Setup

Dimensions of the experiment, number of shots per loop, settings in every experimental point, acquisition axis and many other parameters can be managed using the 'Experiment Axis Setup' panel.

Colored bars represent axis or dimensions of experiment. SpecMan4EPR has multiple axis types. Each axis has size (or trace length for signal axis) and can be repeated number of times (parameter reps or shots fro signal axis).

White bars with with green text represent data acquisition streams. The order of streams is not significant. Streams are declared in PPL script (see signal keyword). Stream parameters can be edited using button that launches a dialog.

White bars with black letters represent variables. Variables belong to the axis above them. Variables of the same axis are set from top to bottom.If variables have wrong definition their names are changed to red. If variables values are entered with errors or amount of variable values is lower than axis size, the color of text is changed to red. Variable parameters can be edited using button that launches a dialog.

The experiment starts with execution of the lowest axis (). Then the first indexes of all axis from bottom to top are selected. The signal axis is located in the most inner loop of execution.

To create new axis of the experiment one should right click on the variable that will belong to the new axis. In pop-up menu the icon of desired axis should be selected. To create new variable one can either add new variable declaration to PPL script or right click somewhere in the exp panel and choose Add variable in the pop-up menu.

Right click pop-up menu options
Axis	Expand/Collapse	Show or hide variables and streams that belong to this axis
	Edit size	Size (length) of axis. Affects amount of data collected.
	Edit repeats	Number of repetitions for the same axis. Corresponding data will be summed.
	Move up/down	Change the order of axis. For ordinary and sum axis only.
	Axis type icon	Change axis type.
	Random axis	Indices are random. If this option is not chosen indices of the axes are sequential.
	Fly back	When all indexes are selected, the first index is selected again.
	Pause before each point	Prior to any axis point execution the program is going to the pause mode.
	Add variable	Associate variable or stream to the axis. Definition of streams for transient axis has to be done using PPL script (see signal keyword).
Variable	Add variable	Associate variable or stream to the parent axis. Definition of streams for transient axis has to be done using PPL script (see signal keyword).
	Delete variable	Delete variable or stream. Streams associated with transient axis has to be deleted using PPL script (see signal keyword).
	Edit variable	Change variable association using dialog.
	Edit value	Edit variable's parameters using dialog.
Stream	Edit variable	Change variable association using dialog.

Run-time axis appearance.

	Dimensions of experiment that are acquired on hardware have blue color.
	Dimensions of experiment controlled interactively are yellow and show progress bar.
