Math
Math traces (F1-F2)) 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 (Cx), zoom (Zx), or memory (Mx) trace. It can even be applied to another
math trace (Fx), allowing you to chain operations (for example, trace F1 can show the average of C1, while
trace F2 provides the integral of F1). Functions such as Trend can be applied to measurement parameters
(Px) to plot the history of the measurement.
In addition to the extensive math capabilities that are standard with every oscilloscope, 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 datasheets on the Teledyne
LeCroy website at teledynelecroy.com. If you have installed software options, these capabilities are
accessed through the oscilloscope Analysis menu, rather than the Math menu, although special measure
parameters and math functions will be available when using Measure and Math dialogs.
Setting Up Math Functions
This procedure explains how to set up math function (Fx) traces. Function traces take as input one or more
channel, zoom, memory or math traces and output a new math trace.
1. From the menu bar, choose Math > Math Setup.
TIP: If you know which function location you'll be using, you can select Fx Setup right from the Math
menu.
2. Choose a location by touching one of the Fx tabs.
3. In Operator1, choose the math operation to perform.
4. The choice of operator drives the number of Source fields you will see displayed. Make a selection in
each 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).
