Product Description
The DisplayMax 5000 provides a complete test solu-
tion for today’s installation workforce. The 5000
series measures analog and digital channel power as
well as quality measurements such as MER, BER
and C/N. Return levels are measured using a built-in
DOCSIS modem, insuring sufficient headroom for
reliable modem operation. Finally, shielding is veri-
fied by measuring Leakage and Ingress. All these
tests from a single, low cost and easy to use field
instrument. The DisplayMax 5000 is the only meter
your installers need.
Field Rugged and Accurate
The DisplayMax 5000 has a rugged aluminum hous-
ing, weather proof keypad, protected LCD display,
virtually unbreakable F-connector bushings and
comes in a padded nylon case. In addition to the
rugged mechanical design, it has a built-in white
noise source that acts as a calibration reference.
Before each reading, the meter adjusts its calibra-
tion, making the 5000 series not only rugged, but
also extremely accurate. The auto-calibration feature
eliminates the need for annual calibration.
Return Levels
Measuring return levels not only verifies a connection
with the CMTS, but also insures sufficient headroom
for reliable modem operation. With the press of a sin-
gle button, DisplayMax 5000 displays the return level
on a large easy to read display. If levels are too high,
the installer can take measurements at various loca-
tions to pinpoint and fix the source of the problem.
MER, BER & C/N
Quality measurements are necessary to insure reli-
able performance of the customer’s equipment. MER
and BER measure signal quality of a digital channel,
while C/N measures signal quality of an analog
channel.
Leakage and Ingress
Leakage and Ingress are essential tests to verify
good shielding properties of the home and drop
cable as well as any component attached to the
cable. An installation that is free from ingress and
leakage will provide reliable service to the customer
– both today and in the future.
