Expected Result(s)
Velocity scale determines pulse repetition
frequency. If the sample volume gate range
exceeds single gate PRF capability, the
system automatically switches to high PRF
mode. Multiple gates appear, and HPRF is
indicated on the display.
Adjusts the sensitivity to get more accurate
envelope trace.
Adjusts the resolution in frequency domain.
Optimizes the smoothness of the spectrum.
Different levels can be selected.
Optimizes image quality and allows user to
reduce beam intensity. 10% increments
between 0-100%. Values greater than 0.1 are
displayed.
Sizes the sample volume gate.
Wall Filter insulates the Doppler signal from
excessive noise caused from vessel
movement.
