channel PASS or FAIL indicator
scan PASS or FAIL indicator
A "P" for PASS or "F" for FAIL appears for
each channel selected by the marker.
This indicates that the channel meets the
requirements which were set up in the
LIMITS EDIT menu: minimum video level,
maximum ∆ video level, maximum ∆
video/audio difference, and minimum ∆
video/audio difference (see page 26).
A PASS (P) or FAIL (F) indication is also
given for the displayed scan spectrum.
This will indicate "–" until the first scan is
completed. The channel status of a "DIGI"
or "SNGL" type channel is not used to
determine PASS or FAIL for the scan.
This is used ONLY for "TV" type channels
with audio and video carriers.
NOTE: A "pass/fail" status is not
available for single or digital chan-
nels.
Frequency Spectrum
Scanning Measurement
The Model One can be set to display
spectrum measurements with spans
ranging from 2 to 50 MHz. It can also be
set for a full spectrum scan (5 to 870 MHz)
with sampling at each video carrier
frequency in the selected channel plan.
