Atec Tektronix-2715 - Manual

Digital and Analog Testing for Hybrid
Networks
The 2715 Cable TV Spectrum
Analyzer now includes auto-
mated tests for both analog
and digitally-modulated
channels. When you are
ready to begin installing
digital transmission of video,
data or voice, the 2715 is
ready to help. After setting
up the 2715 with the new,
companion Cable TV RF
Measurement Software for
Windows, the analyzer auto-
matically determines the cor-
rect measurements for each
channel type – analog, digi-
tal, FM or pilot.
Dependable, In-service Analog
Carrier Measurements at an
Affordable Price
Now you can make more
proof of performance and
other cable system measure-
ments without disruption of
service to subscribers. And
you can minimize the incon-
venience of making measure-
ments at the output of set-top
converters. The 2715 pro-
vides accurate and automated
measurement of carrier-to-
noise, in-channel response,
and coherent distortion sig-
nals as well as carrier levels,
frequencies, and more…with-
out removal of video carriers
or modulation. In-service
measurement of CTB requires
an unoccupied channel adja-
cent to the test channel.
Characterize your Digital Channels
Channel averaged power,
noise and distortions on digi-
tally modulated channels can
all be measured by the 2715.
It’s important to understand
the performance of each of
the digital channels in your
system as well as their inter-
action with your analog
channels. Both broadband
random noise-like distor-
tions, and coherent distor-
tions – plus noise – can be
measured. They all can
degrade the bit-error-rate
behavior of your digital
signals. The 2715 includes
