Parameters
P834 TVT Start Duration
Use this feature in conjunction with TVT Start Min (P833) to ignore false echoes (or pick
up true echoes) near the start of the Echo Profile.
Enter the time (in ms) for the TVT Curve to decrease from the TVT Start Min (P833) point
to the TVT Curve baseline.
P835 TVT Slope Min
Enter the minimum slope (in dB/s) for the middle of the TVT Curve.
Use this feature to adjust the slope declination, and use it in conjunction with TVT Start
Duration (when a long flat TVT Type is selected) to ensure the TVT Curve remains above
the false echoes in the middle of the Echo Profile. Alternatively, if TVT Type is set for TVT
Slopes (P830 = 6), preset is 2000.
