After selecting from the Trace Overlay menu, a window appears
that requests you to enter a base trace and an overlay trace.
Enter each trace and select “Enter.” The overlay trace appears
in the window of the base trace. Enter other traces as you desire,
and select “Done” when you are finished.
NOTE: Only one wave form may be overlaid onto any base trace.
Scale Traces Menu
You can scale analog wave forms to an Actual Scale or a
Normalized Scale. Actual Scale shows an analog wave
form in relation to the other six wave forms. When you
choose Normalized Scale, the wave form is scaled with
respect to the largest amplitude for that wave form only.
In other words, the peaks expand to fit that individual
window. From the Scale Traces menu, select Actual Scale
or Normalized Scale. The program launches in Actual
Scale.
Select Status Trace Menu
