Configuring The Instrument For A Phased Array Probe - GE Phasor CV Operating Manual

2. Setting Up for Phased Array Measurement
2.3.2 Configuring the Instrument for a
Phased Array Probe
When a phased array probe is connected, various in-
strument settings must be input to match the probe and
(if so equipped) its attached wedge. Data related to a
probe is printed on its body and connector. Probe-related
functions are accessed via the PROBE Menu shown in
Figure 2-3. These settings must be adjusted each time
a different phased array probe is installed. Note that all
probe-related settings can be stored in a data set file as
described in Chapter 6.
NOTE: When a dialog style probe is connected to the
instrument, a message will be displayed prompting
you to press to accept Dialog Probe data. When
is pressed, the connected probe's part number
and serial number will be automatically updated in the
instrument.
NOTE: Probe and wedge geometry, scan parameters,
and user-inputted offset values influence the displayed
image. The physical relationship between these set-
tings and the displayed image are graphically repre-
sented by the Imaging and Measurement Map shown
in Section 2.3.3.
Inputting Probe Part and Serial Number (PROBE-
PRB DAT-PART or SERIAL NUMBER)
Step 1: Activate the PRB DAT Submenu (located in the
PROBE Menu) by pressing
FIGURE 2-3—The PROBE Menu allows the user to input settings related to probe and wedge configuration. Delay-law
recalculation is required when those functions indicated here with CALC are modified.

below it.
Step 2: Press next to one of the selections (PART
NUMBER or SERIAL NUMBER) two times.
Step 3: To change the active digit of the part or serial
number (to match the value printed on the side of the
probe connector), turn the Function Knob. To make the
next digit active, turn the Gain Knob.
Step 4: Press again to complete the PART or
SERIAL NUMBER entering process.
Defining the Probe Geometry (PROBE-PRB GEO-
FREQUENCY or NUM ELEMENTS or PITCH)
Step 1: Activate the PRB GEO Submenu (located in the
PROBE Menu) by pressing
appear down the left side of the display.
Step 2: Press next to one of the selections (FRE-
QUENCY or NUM ELEMENTS or PITCH).
Step 3: To change the displayed value (to match that
printed on the probe), continue pressing
the function knob. You'll note that the following settings
are available:
FREQUENCY – 0.5 to 10 MHz
NUMBER of ELEMENTS – 1 to 64
PITCH – distance between the centers of two
adjacent elements (approximately 0.010 to 0.197
inches or 0.25 to 5 mm)
Step 4: The selected parameter will be set to the value
last displayed. Recalculation of delay laws is required.
