NOTE: TCG points can be manually stored one beam
at a time, or for all beams in the scan at once. To edit
all beams at once, set the BEAM CURSOR Function
at either of its extreme positions. This condition, shown
in
Figure 3-10, causes all available beams (such as 1
through 57, if the scan includes a total of 57 beams)
to be listed. Alternatively, set the BEAM CURSOR
Function to each beam (Step 4 below), continue with
the process of recording the TCG point settings for that
beam, then continue to the next beam until all beams
in the scan are complete. This results in a single TCG
point being stored (Step 6 below) and allows the pro-
cess to continue if additional points are required.
To manually define a TCG curve:
Step 1: Access the NRM/TCG Submenu (located in the
UT Men u) by pressing
.
Step 2: Start the recording process by pressing (two
times)
next to RECORD so that POINT 1 appears.
Step 3: Access the TCG EDIT Submenu.
Step 4: Press
to activate the BEAM CURSOR
Function and set its value to a single beam, or turn in to
one of it’s extremes to select all beams in the SCAN (see
Figure 3-10).
Step 5: Press to activate the POINT Function and set
its value to NEW.
Step 6: Press
next to POINT POS. and POINT GAIN,
then turn the Function Knob. Set these values to corre-
spond with the desired position and applied gain level of
the first TCG point.
Step 7: When the first TCG point’s position and gain
are correctly set, press
next to POINT (two times) to
record the defined point.
Step 8: Turn the Function Knob to set the POINT Func-
tion to NEW again and continue the process described in
Steps 4 through 8 until up to 15 desired TCG points are
entered.
3.6.5 Editing TCG Points
After creating a TCG Curve, modifications can be made
to the amplitude or time-based position of existing points.
In addition, more points (up to a total of 15) can be added
to the existing TCG using the TCG EDIT Submenu.
FIGURE 3-10—TCG points can be manually inserted to create a new TCG curve or to add new points to an existing
curve. Note that TCG data can be stored or edited for one beam at a time or for ALL beams in a scan by adjusting the
BEAM CURSOR Function.
