Model One Operating Manual

LEVEL MEASUREMENTS

The Model One can display a single
channel, groups (up to eight) of “favorite”
channels or all channel amplitudes.

The channel plans for the display can be
configured either on the unit’s front panel
or downloaded from a PC.

Single Channel Display

When tuned to a single channel, the
Model One displays bar graphs for the
video and audio carriers. It also shows
numeric readouts of the carrier amplitudes
and V/A difference. In addition, the unit
provides a spectral display of
intermodulation products or other undes-
ired signals that may be present.

TILT AND “FAVORITE” GROUP
DISPLAY

Press the

TILT

button to display a graph

showing the amplitudes of up to eight
user-selected video carriers. This display
also shows the calculated difference in
amplitude (tilt) between the HIGHEST and
LOWEST channels in the user-selected
group. Press

TILT

again and the Model

One displays a numeric list which shows
the amplitudes of the carriers in the group.

SCAN DISPLAY

Press the

SCAN

button to display the full

span of video carriers. This mode is
useful to make a quick check of your
system’s overall flatness and amplitude.

The Model One can be set to display both
audio and video carriers at reduced
frequency spans. This means that you
can impose amplitude limits on the
display. By using the unit’s frequency
marker, you can zoom in on any suspect
channel that appears in the display.
