800CLI Frequency
The DisplayMax 800CLI is powerful enough to maintain
the headend, yet simple enough for routine installation
checks. With a wide range of measurement options,
a technician can quickly check an individual channel,
favorite channels, all channels, tilt, leakage, ingress,
C/N or HUM.
The graphic display allows a technician to view the full
system response and quickly identify problems such as
low level, roll-off, suck-outs or missing channels. In the
ingress mode, the graphic display shows a spectrum
analyzer view of the full return path, revealing any unwanted
ingress signals.
All multi-channel modes are supported by an automatic
pass/fail test that compares all measured channels
against user defi ned paraMETERS. In less than one
minute a headend technician or installer can scan up
to 135 channels and verify that all analog and digital
channels are within tolerance.
Data recording permits all measurements to be saved
and downloaded to a computer.
Highlights:
- Quickly tune and display
the average power
of a single digital channel.
The spectrum
analyzer display
shows how the power
is distributed over the
channel’s bandwidth.
- Quickly tune and display
the picture carrier,
audio carrier and dB
difference on a single
screen. Monitor audio
quality on the built-in
speaker.
- Find leakage problems
quickly using the
search mode. Change
to the measurement
mode to accurately
measure the leakage
value based on your
distance to the leakage
source.
- Check for ingress on
the return-path. The
spectrum analyzer
display reveals the
ingress signals that
interfere with digital
services such as VoIP
and high-speed data.
- View the response
of the entire system
including both analog
and digital channels.
Press the ‘check’ key
for an on-screen pass/
fail summary of the
system.
- View only ‘Favorite’
channels for a quick
snap-shot of the system.
Press the ‘check’
key for an on-screen
pass/fail summary.
