5
Speed
By touching up or down, four different sweep speeds can be selected.
6
RT Trace (Real Time Auto-Trace) The envelope curve of the Doppler spectrum (maximum velocities) and the
corresponding evaluations are automatically displayed on the monitor.
7
Display Format
Doppler spectrum is displayed below the B mode image or on its right side.
8
Invert
To invert the Doppler spectrum display in relation to the direction of the flow.
9
Angle
The angle cursor can be turned in both directions without stop. By pressing the angle
knob repeatedly the angle correction switches from +60° to 0° and to -60°.
10
Baseline
Adjusting the baseline is possible in read- and write Mode (up/down in 8 steps).
11
WMF (Wall Motion Filter)
Used to eliminate Doppler “noise” that is caused by vessel wall motion.
12
PRF
The Velocity Range display is governed by the pulse repetition frequency (PRF)
Exceeding the maximum PRF, the HPRF-Mode is automatically switched on.
13
Dyn.Contr.
Dynamic Range adjusts the display cutoff of the Doppler analysis waveform.
14
Center Freqeuency
It serves for selection of the required transmit frequency.
15
Scale Unit
To select the displayed measuring system (in relation to the zero-line).
16
Display Format
