Markers and Limit Lines
The easiest way to manage markers is to turn one on and use the mouse to drag it to the
desired position. The marker tool bar is shown in
Figure 7-4 . Marker number 1 is
On
in the
figure below. Markers can be set to an exact value by pressing the “
e
” button, which displays
detailed marker controls, numeric value entry, peak find, and valley find.
The dark button on the left turns on the limit line. Once on, it can be dragged to the desired
place, or put on an exact y-axis value by entering a number.
Marker Presets
The fastest way to manage markers on multiple traces is to use the preset function. The
marker and limit line preset toolbar allows users to quickly set all markers and the limit line
to pre-defined values on similar traces (
Figure 7-5 ).
First set the markers and limit lines on a typical trace to the desired values. Then, press the
red “
e
” or edit button on the Preset toolbar. This puts the preset buttons into “learn” mode.
Now, press a preset button (1 to 7). This programs the preset button where to put the markers
and limit lines. Finally, press the red “
e
” button again to exit the learn mode.
The programmed button is now enabled. Line Sweep Tools can program up to 7 buttons with
preset markers and limit line.
To use the preset, just press it and the markers and limit line will display at the programmed
locations even when switching to a new trace. The two arrow keys make going to the next, or
previous, trace simple. Using presets, a dozen similar traces can be reliably validated in
seconds.
