(table)
The Full Scan measurement mode provides two views (Graph and
Table). Both views continuously update measurements for all the
channels. Both views also display all signal level measurements in the
current user-selected signal level units as specified in “Regional Pref-
erences” on page 43.
The Full Scan Table view displays each available channel number,
their video level readings, and available first and second video audio
deltas.
The highlighted channel in the Table view corresponds to the marked
channel from the Graph view and vice-versa.
When a channel reading is outside the limit boundaries, a Fail icon is
displayed and an up or down arrow is displayed to the right of the
Channel Status area below.
When you press the up or down arrows continuously, the highlight bar
moves faster.
NOTE
To perform a repetitive movement of the marker, press and hold the
left or right arrow key.
NOTE
An audio reading is not applicable to single type, DOCSIS or digital
channels.
