How to open
This dialog box is opened from the Active menu.
Description
The Echogram dialog box is the main source for all echogram presentation choices.
Note
The setting you choose will only be valid for the currently active echogram. Click in any echogram view to make it active. The active echogram view is identified with a thicker border. Select Apply to save your settings without closing the dialog box.
The dialog box offers tabs to present the settings.
•  Lines
The Lines page in the Echogram dialog box allows you to control the horizontal and vertical lines used in the echogram presentation. You can make the bottom easier to see, and add lines that hold additional information. The vertical scale of the echogram presentation can be changed. If you wish to add annotations to your echogram, these are enabled on this page.
•  Echogram
The Echogram page allows you to choose which type of echogram you wish to display. You can also control the TVG (Time Variable Gain). The ME70 can work with several different TVG compensation settings. The TVG (Time Variable Gain) compensation is designed to counteract the natural phenomena of geometric spread and absorption loss.
•  Horizontal Axis
The echogram travels from right towards left across the ME70 presentation. On the Horizontal Axis page you can choose the horizontal scale of the echogram. This controls the "speed" of the echogram.
Tip
You can also select TVG setting with the TVG function. The TVG (Time Varied Gain) function is located on the Active menu.
