The Expression builder consists of 4 areas.

1	Signal tree	3	Notes on the function
2	Function tree	4	Input field

In the signal tree on the left (1), you can find the original signals from the data file and additionally all the expressions created in the Expression builder. Select the signals or expressions to calculate with here.

The function tree on the right (2) shows all available mathematical operations and other functions sorted by topic.

If you select a function in the function tree, notes on the function (3) are displayed below, e.g. the syntax.

Enter the desired expression in the input field at the bottom (4). A tooltip for the function appears if the function is selected in the input field.

The <Reset expression> button deletes all entries from the command line.

If you activate the option Reference signals by name, the signal names are used in the printout instead of the usual signal identification [module number:signal number].

Note
	When using the signal names as a signal reference, make sure that the signal names are unique.
