Overview
Math allows you to perform simple and complex mathematical calculations on
your signal, or on a zoom or memory (reference waveform). The oscilloscope can
be operating in any acquisition mode (Real-Time, RIS, or Roll Mode) when Math is
created.
Math traces are defined with an Operator and a Source. Examples of Operators
include Add, Subtract, Multiply, Divide, and FFT. Sources are channels, zoom
traces, or memories (reference waveforms). Some Operators require two sources,
and some only one source. The oscilloscope shows how many sources you need to
define when you choose the Operator.
Math is always displayed in a separate half-height grid at the bottom of the
display, separate from your other traces. This makes it easier to interpret Math
information if the math scale is different from the channel scales. If you also have
Zoom traces showing when you turn the Math trace ON, three grids are shown on
the display, each at one-third the height.
Each Math trace can also be zoomed without setting up a separate zoom trace.
This reduces a step, and gives you more capability to understand the exact feature
of interest without having to create another trace. Simply use the zoom controls in
the Math dialog, or use the Vertical and Horizontal controls for position and scale
change in both axes when the Math trace is active.
One powerful feature about WaveSurfer MXs-B Math traces is that they are
calculated to 16-bit vertical resolution. Therefore, you can vertically zoom the
Math trace and still maintain very high resolution when viewing the zoomed trace.
