Math
Math traces (Fn) display the result of applying a mathematical operation to a source trace. The output of a
math function is always another trace, whereas the output of a measurement parameter is a tabular
readout of the measurement.
Math can be applied to any channel (Cn), zoom (Zn), or memory (Mn) trace. It can even be applied to
another math trace, allowing you to chain operations (for example, trace F1 can show the average of C1,
while trace F2 provides the integral of F1).
In addition to the extensive math capabilities that are standard with every instrument, enhanced math
analysis tools customized for various industries and applications are offered through optional software
packages. To learn about math tools available in each optional package, see the product datasheets at
teledynelecroy.com.
If you have installed software options, the new capabilities are usually accessed through the Analysis
menu, rather than the Math menu, although special measure parameters and math functions will be
available when using Measure and Math dialogs.
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 (Fn). 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 Fn tabs.
If you know which function location you'll be using, you can select Fn Setup right from the Math
menu.
3. In Operator1, choose the math operation to perform.
