3. Operating in Phased Array Mode
This chapter of the manual explains how to adjust the
instrument’s display to most effectively evaluate A, Sec-
tor, and Linear Scans acquired in Phased Array Mode.
In this chapter, you’ll learn how to:
•
Set the displayed view to include either A-Scan,
Sector (or Linear) Scan, or a combination of the two
(
Section 3.1 )
•
Select the measured values to be displayed
(
Section 3.2 )
•
Link and Unlink the A-Scan’s position with the
Sector or Linear Scan when both are displayed
(
Section 3.3 )
•
Control the Beam Cursor’s Angular Position with the
Function Knob
(Section 3.3)
•
Assess on-screen images in Freeze Mode
(
Section 3.4 )
•
Adjusting the gain setting ( Section 3.5 )
•
Operate in TCG Mode ( Section 3.6 )
3.1 Selecting the Displayed View
(Phased Array)
When operating in Phased Array Mode, there are three
ways in which the resulting image may be viewed. Press
to change the view mode, noting that each change
requires a few seconds to update the display screen.
During this brief delay,
appears near the upper right
corner of the screen. If the A-Scan and Sector (or Linear)
Scans are displayed simultaneously, the relation of the
two scans with respect to each other can be modified as
described in
Section 3.3 . Available views include:
•
Sector or Linear Scan only ( Figure 3-1 )
•
Sector or Linear Scan with A-Scan ( Figure 3-2 )
•
A-Scan only
As described in Section 2.5 , switching between Sector
and Linear Scans requires recalculation of the phased-
array delay laws. If a change is required, access the
ELECTRNC Submenu (in the SCAN Menu) and choose
the TYPE of scan. Note that the IF Gate’s LOGIC Function
must be set to OFF before selecting a sector scan type.
FIGURE 3-1—Either the Sector (shown here) or Linear Scan can be displayed by itself. Note key on-screen axes and
other features identified here.
