The determination of the envelope curve requires a clear and low-noise recording of the
Doppler spectrum. Otherwise the reliability of the displayed measurement results may not be
ensured!
1.
After obtaining a feasible Doppler spectrum, press the [Calc] key on the control panel.
2.
Select the desired measurement item and then select [Manual Trace]. A cursor appears
on the Doppler spectrum.

To re-adjust the traced line, press the upper trackball key [Undo] repeatedly.
4.
Trace to the end of the period and press the [Set] key again to fix the mark.
Remark: To select the Doppler measuring results, which should be displayed after the
measurement (= "Auto/Manual Trace") and to select if the envelope curve will be performed
with a continuous trace line or by setting points (= "Manual Trace Mode"), review: Application
Parameters
(chapter 'The Measure Setup Pages' on page 11-109 ).
1.
After obtaining a feasible Doppler spectrum, press the [Calc] key on the control panel.
2.
Select the desired measurement item and then select the [PS], [ED], [RI] or [PI] key. A
