Setting Up TOP View for TIMED
Operation
In TIMED operation, the instrument continuously acquires
scan data, which is added to the display’s buffer. The time
interval between data acquisition, which sets the TOP
View display’s “scrolling” speed, determines the duration
of DISPLAY LENGTH. This calculated value represents
the amount of scanning time represented on the TOP
View display at any one time. Additional scanning data
scrolls to the instrument’s data buffer and is immediately
viewable anytime the display is stopped (
Section 8.3
)
or
is pressed. Refer to
Figure 8-2
and follow these
steps to configure the instrument for TOP View operation
in TIMED mode. The resulting TOP View operation is
shown in
Figure 8-4
.
Step 1:
Activate the CLOCK Submenu (located in the
SCAN Menu) by pressing
below it.
Step 2:
Press
to set the CLOCK Function to TIMED.
Step 3:
Press
and turn the Function Knob to set the
duration (in hertz) of the SAMPLE INTRVL. The sample
interval equates to the number of TOP View data lines
acquired and displayed per second.
Step 4:
Note that the calculated value of DISPLAY
LENGTH automatically updates. This calculated value
represents the amount of scanning time represented on
the TOP View display at any one time. While scanning a
test piece, stopping the display (
Section 8.3
) allows the
operator to scroll back through TOP View data that’s held
in the data buffer.
NOTE:
While scanning in TIMED mode, TOP View data
is first added to the display screen. When the screen is
full, the initial data “scrolls” into the instrument’s data
buffer. Scrolling direction is defined in Step 5.
When
the buffer is full, acquiring new data automatically
causes the oldest data in the buffer to be overwrit-
ten.
At any time, the TOP View scanning process can
be stopped, allowing on-screen and buffered data to
be stored in a data set (
Section 8.4
).
Step 5:
Press
to activate and set the NEW DATA
Function in the IMAGE Submenu (located in the DISPLAY
Menu). The selection sets the screen location (LEFT,
RIGHT, TOP, or BOTTOM) at which newly acquired TOP
VIEW data is added to the display screen. This function
controls the display screen scrolling direction.
FIGURE 8-1—The A- and/or B-Gated regions in a sector or linear scan provide the data sources from which the TOP
View display is generated.
