3. Perform the following steps if your analyzer has Option 107 installed and
you want to perform a gated (non-interfering) measurement (modulation
turned on). Note that you will only have gotten to this point if GATING is
set to NO.
a. Press GATE ON/OFF in the CARRIER/NOISE menu to perform a gated
(non-interfering) measurement.
b. The analyzer will search for a quiet line and depending on the setting
of PAUSE it will either pause or automatically continue if it finds a
quiet line. If it does not End a quiet line it will display VIDEO SYNC NOT
RECOGNIZED. At this point you can remedy the reason, or if a quiet
line was not found because of noise, you can press LINE SEARCH to
reinitiate a quiet line search. Another possible reason for failure to End
a quiet line if that the input coupler is not in place with its coupled leg
connected to TV IN.
c. Entering line numbers and the softkey FLD BOTH/EVEN/ODD can be
used to manually search the vertical interval for a quiet line.
