Selection Tool Tip Description Settings
PRF PRF Adjusts the scale factor of the Pulsed Repetition
Frequency (PRF). Transducer-
dependent
Baseline% Baseline Shifts the spectral baseline position. ---
Invert Invert Reverses the spectrum relative to the baseline. When
the spectrum is inverted, Doppler audio is also inverted.
On, Off
60/0/60 Coarse Angle
Correct
Selects a sixty-degree or zero-degree Doppler angle for
use by the system to calculate velocity.
---
Ang Angle Correct Identifies the Doppler angle used by the system to
calculate velocity and is an indicator to aid in obtaining
an optimal Doppler angle. Adjusts the Doppler angle in
degree increments.
0 to 89
degrees
D-TEQ Doppler Tissue Activates TEQ ultrasound technology for Doppler. ---
(current
setting)
Transmit
Frequency
Changes the transmit frequency of an active
multi-frequency transducer during Doppler.
Transducer-
dependent
Filter Wall Filter Rejects low frequency signals, for example, signals
generally caused by tissue clutter. Dependent on
transducer and
exam type
Gate Gate Size Adjusts the size of the Doppler gate. Dependent on
transmit
frequency
Sweep Sweep Speed Adjusts the horizontal speed of the Doppler spectrum. 1 , 2 , 4 , 6 , 8
Steer Rev.
Steer Reverse Reverses the Doppler angle, gate axis, and Doppler
spectrum.
Note: Applies to linear array transducers only.

DR Dynamic Range
Controls the overall contrast resolution of the image. 30 dB to 70 dB
in 5 dB
increments
Maps Maps Selects a processing curve that assigns echo
amplitudes to gray levels. A, B, C, D, E,
F, G, H
Tint Tint Changes the color of the Doppler spectrum by adding
blue, red, yellow, or green to the gray in a gray map. 0 to 11
T/F Res Time/Frequency
Resolution
Adjusts Time/Frequency resolution. A, B, C, D, E,
F, G, H, I
