Math Function Set Up

Use the Function dialog to set up math function traces. Math functions take as input one or more
channel, zoom, memory or math traces and output a new function trace (Fx) . Any additional settings
required for the operator will appear on a subdialog at the right of the screen.
Single functions perform one operation on one or two input sources.
Dual functions chain two operations to arrive at a single result. This saves you the effort of having to
chain two separate math functions. As with single functions, the number of sources required will vary
based on the operation. You may need only one source for Operator1, but two for Operator2 (the result
of the first operation counts as one source).
Setting Up New Functions
1. From the menu bar choose Math > Math Setup, or press the front panel Math button.
2. Choose a location by touching one of the Fx tabs.
If you know which function location you'll be using, you can select Fx Setup right from the Math
menu.
3. Choose a single f(x) or dual g(f(x) operator function.
You can also choose Web Edit, in which case this function is added as a terminal to the
processing web. See the instructions for
4. In Operator1, choose the math operation to perform.
5. The choice of operator drives the number of Source fields you will see displayed. Make a
selection in each field, or drag the source channel descriptor box to the field.
A Summary of the function you are building appears on the dialog. Refer to this to be sure your
sources are in the proper order to yield the function you want (e.g., C1-C2 vs. C2-C1).
6. If the operator you've selected has any other configurable settings, you'll see a subdialog of the
same name as the operator. Touch the tab to open the dialog and make any further settings.
These are explained on the dialog.
7. If you're creating a dual function, repeat the procedure for the second operator.
