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 and then the Clear 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 setting. (See Table 20:
Word recognizer data on page 275.)

d. Touch Enter.
e. Center Cursor 2 in the high of the waveform just to the right of the center
graticule line. (See Figure 43: Isolated 1 triggering on page 276.)
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 ps. Enter pass or fail in the test record.
g. Touch the Edit and then the Clear 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 43: Isolated 1 triggering on page 276.)
k. Verify that the instrument triggers at the 1 in the input signal. The
absolute value of the T1 cursor readout must be ≤325 ps. Enter pass or
fail in the test record.
l. Touch the Edit and then the Clear button.
m. Enter data into the Serial Pattern Data field for the next setting in the
table that is not yet checked. (See Table 20: Word recognizer data on
page 275.)
n. Touch Enter.
o. Center Cursor 1 in the high of the waveform just to the left of the center
graticule line. (See Figure 43: Isolated 1 triggering on page 276.)
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.
