Operator's Manual
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 functions can be applied to any channel (C
x
), zoom (Z
x
), memory (M
x
), or even other math traces (F
x
), allowing you
to chain operations. For example, trace F1 can show the average of C1, while trace F2 provides the integral of F1.
Set Up Math Function
This procedure explains how to set up math function (F
x
) traces. Function traces take as input one or more channel,
zoom, memory or math traces and output a new math trace.
For more information about creating math traces that plot the results of applied measurements, see
.
1. From the menu bar, choose
Math > Math Setup
.
TIP:
If you know which function location you'll be using, you can select
F
x
Setup
right from the Math menu.
2. Choose a location by touching one of the
F
x
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).
5. If the operator you've selected has any other configurable settings, you'll see a right-hand dialog 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.
There will also be a Zoom dialog where you can optionally rescale the math trace. This does not affect the scale of
