3. Touch any of the icons to select the math operator (function) that you
desire. Scroll down through the list using the scroll bar on the rights
side of the pop-up menu.
4. Once the Operator is selected, the pop-up menu closes and the Math
trace is re-defined.
Using Dual Operators
If you have purchased the MathSurfer Advanced Math option (standard on
WaveSurfer MXs-A), you can select a second Operator. Do this by selecting
Dual from the Single/Dual button selection.
A second Operator is shown. Make changes to it the same way as with the
first operator.
Two Operators can be helpful in some situations. For instance, you can
compute an FFT, and then Average the FFT result over many computations
by making the first Operator an FFT and the second operator an Average
function. Or, you can make the second Operator a Rescale function to
change units and rescale information for a non-standard calculation.
The channel source defaults to C1. Touch inside the source field to select a
different source (a channel, a memory, or a zoom).
Close the Math dialog by either pressing the front panel Math button
again, or touching Close on the on-screen dialog.
