Math and Measure
Graphing
The Graph button on the Function (Fx) dialogs allows you to plot the results of an applied
measurement parameter using histogram, track, or trend. Choose the source, the measurement
parameter, and the type of plot to draw. See
Histogramming
and
Track and
Trend.
Tip: The plots are the same as those created using the toolbar on the Parameter (Px) dialog.
As with other math functions, configurable settings will appear on subdialogs after the plot is
selected.
Adjusting Memory or Math Traces
Unlike channel traces, the scale of memory (Mx) or math function (Fx) traces can be adjusted directly
without having to create a separate zoom trace. The same set of
zoom factor controls
used for zoom
traces appear on the Zoom subdialog, but in this context they only rescale the active math or memory
trace rather than create a new zoom. This applies to any trace that is created as a math function (Fx)
trace, including traces generated through analysis options and graphs.
You can, if you wish, create a separate zoom trace from a memory or function trace the same as you
would normally create a zoom (draw a selection box, apply the Zoom math operator, etc.). In this
case, you choose one of the zoom locations (Zx) in which to draw the trace, but the source trace
remains at the original scale.
Math Dialog
Once a math function has been created and saved on the Function (Fx) dialog, use the main Math
dialog to quickly enable/disable it.
To open the Math dialogs, touch the front panel Math button, or from the menu bar choose Math >
Math Setup. Select the On checkbox next to each function you wish to display.
To modify a function, touch the Fx button.
To erase all functions from their locations, touch Reset All.
To restart the counter on cumulative functions (like Average), touch Clear Sweeps.
