Duplex Activates simultaneous Duplex Doppler mode for PW
Doppler vascular, abdominal, or OB/GYN exams. Not
available when Color is on.
Filter Removes audible signals of frequencies below the hertz
level specified. For lower filter settings, both audio and
spectral information are removed. Is displayed only
when Spectral is on.
Focus Repositions the acoustic depth of the color focal zone.
Gain Adjusts the amplitude of received Doppler signals and
noise. Is displayed only when Spectral is on.
Gain (Angio) Adjusts system sensitivity to received angio signals.
Increasing the angio gain percentage increases the
amount of color displayed. Is displayed as part of the
Angio and BMode Live control set.
Gate Length Adjusts the size of the PW gate.
Line Adjust Provides access to Line Angle. When off, the system
positions the PW Doppler interrogation line
(Intelligent Doppler feature) based on the Optimum
Angle setting. Available only with linear transducers.
Line Angle Lets you manually position the PW Doppler
interrogation line. Only available when a linear
transducer is active and Line Adjust is on.
Nonimage Xducer Activates the connected nonimaging transducer.
Produces a hard copy of the screen display. If the
onscreen image is live, it briefly freezes during printing
and then returns to live imaging. You also can use the
foot switch pedal to print information.

the Doppler spectrum. Removes low-level Doppler
signals. Is displayed only when Spectral is on.
