The middle column is used to setup the signal’s gain function. At first opening of the
received sounding data, the gain function will be similar to one that was used at data
acquisition. You are able to set any different gain function. To open Gain function
window simply press on the middle vertical line Gain with your left mouse button.
Right after the first output of a newly created profile, gain function will have the
same form as it was specified at data receiving. To change the gain function you should
point mouse cursor on any vertex, so it will change its shape to arrowed crosshair under
which is the value of gain in dB. Press and hold the vertex and move it left or right, so the
gain will be correspondingly changed. The result of your actions will be immediately
displayed on the profile.
If you need multi vertex gain function, you can add new vertexes (up to 10). For this
purpose press the button and click on desired point on the Gain Function window and
the new vertex will be created. To remove unwanted vertex you could use button or
popup menu’s item Delete Vertex. Mouse cursor will be changed to a crosshair. Now you
can simply click on the vertex that you want to remove (gain function needs at least two
extreme vertexes, which are not removable).
To import the desired gain function from a different data file press the button and
choose data file by double click. You can also apply this gain function to the all currently
opened profiles by pressing button .
If you need higher gaining (the common maximum gain is 84 dB), up to 168 dB, you
could turn on Double Gain option, by pressing button or choose Tools / Gain
Function / Double Gain menu item of Main menu.
There is a possibility to built-in gain function to the raw data of the profile by
pressing button or choose Tools / Gain Function / Built-in Gain Function menu item
of Main menu.
Warning: while gain function building-in the raw data of the profile are changing,
and if you overwrite this file, your raw data lost.
By pressing (trace curve), (power curve) and (attenuation curve)
buttons you can change which curves you need to be shown or hidden in the Gain
Function’s window. Track bar located beneath the buttons can be used to regulate curve’s
transparency.
The lower column is used for digital filter in frequency domain setup. At the first
opening filter’s frequencies will be the same as they were setup at georadar adjustment
dialog box. Lower column will be crossed if in sounding mode digital filter was not used.
Double-clicking on the lower column will activate/deactivate digital filter, one click will
open filter digital filter setup window.
Vertical and horizontal scale dimensions may be modified by pressing the right
mouse button on the white field of a respective scale. If at data receiving mode manual
positioning mode has been used, you should specify profile length in the Set profile new
length drop-down menu option or at Tools/ Output parameters option in Main menu,
which is also duplicated by the toolbar button . Vertical scale calculations in meters are
