3. Verify that the serial path and pattern matching circuits can do isolated 1s:
a. Adjust the
trigger Level to trigger at 75% (+1 division) on the sine wave.
b. Touch the Edit andthentheClear button.
c. Enter data into the Serial Pattern Data field for one of the settings in
the table that is not yet checked, starting with the first s etting. (See
Table 3-
14.)
d. Touch Enter.
e. Center Cursor 2 in the high of the waveform just to the right of the center
graticule line. (See Figure 3-35 on page 3-109.)
f. Verify that the instrument triggers one Unit Interval (UI) before the 1 in
the input signal. The absolute value of the T1 cursor readout must be
≤325 p
s. Enter pass or fail in the test record.
g. Touch the Edit andthentheClear button.
h. Enter data into the Serial Pattern Data field for the next setting that is
not yet checked.
i. Touch Enter.
j. Center the Cursor 1 in the waveform high nearest the center graticule line.
(See Figure 3-35 on page 3-109.)
k. Verify that the instrument triggers at the 1 in the input signal. The absolute
value of the T1 cursor readout must be ≤325ps.Enterpassorfailinthe
test record.
l. Touch the Edit andthentheClear button.
m. Enter data into the Serial Pattern Data field for the next setting in the table
that is not yet checked. (See Table 3-14.)
n. Touch Enter.
o. Center Cursor 1 in the high of the waveform just to the left of the center
graticule line. (See Figure 3-35 on page 3-109.)
p. Verify that the instrument triggers one Unit Interval (UI) after the 1 in the
input signal. The absolute value of the T2 cursor readout must be ≤325 ps.
Enter pass or fail in the test record.
