Select the units in whichthe marker distance data is presented.Distance Units are also used when setting Time Domain Line Loss. Learn morein. “Distance Units” on page 66.Choose from: m (meters), or Feet.Window LayoutThis setting is used to create additional traces, or select a new layout for tracesthat are already created,Choose from: x1, x2, x2H, x3H, x3, x4H.Learn more about multi-trace configurations in “Multi-Trace Configurations”on page 43.Transform WindowThere are abrupt transitions in a frequency domain measurement at the startand stop frequencies, causing overshoot and ringing in a Time Domainresponse. The Window setting reduces th e abruptness of the frequency domaintransitions. This causes you to make a trade off in the Time Domain response.Zero (0) seconds is always the calibration reference plane. Negative valuesare useful if moving the reference plane.
