Atec Acterna-JDSU-SDA-5000 - Manual (Page 2)

Offers single-instrument testing
of all services
Acterna SDA Series testers are capable
of handling a broad spectrum of inter-
active testing needs including reverse
sweep, multiple-user reverse testing,
portable reverse testing, reverse path
noise testing, quality forward path
digital services with QAM View and
in-service cable modem analysis.
The SDA-5000 Series of Stealth Digital
Analyzers includes the SDA-5000,
SDA-5500, and SDA-5510, each of
which provides a single-instrument
“One Box” solution for engineers and
technicians. The main features include:
Analog testing
– Non-interfering forward RF sweep
– RF level, fast scan, tilt
– In-service carrier-to-noise, hum,
depth of modulation
– Fast spectrum display with CTB/CSO
– Automatic/24-hour testing
(FCC and CENELEC compliant)
Return path testing
– Non-interfering reverse RF sweep
– PathTrak Field View option
pinpoints return path noise
– Reverse Alignment mode
prepares network for cable
modem deployment
– Reverse noise feature shows
accumulated noise/ingress seen
at the headend
– Zero Span Spectrum mode
– DOCSIS/DAVIC compatible cable
modem analysis
Advanced digital testing
– Acterna digiCheck average power
– QAM View digital analysis with
modulation error ratio (MER),
pre/post FEC BER, constellation,
and exclusive noise/ingress under
the carrier measurement

Sweep is the right solution
The majority of all transmission errors
(including digital) are found by meas-
uring the frequency response of the
network. Every physical error in the
network that influences the transmitted
signals will be revealed in the sweep
trace. This means the sweep results are
independent of transmission methods
and formats.
When maintaining and setting up the
HFC network, the goal is to transmit all
signals with the best noise specifica-
tions and the lowest intermodulation
distortion. Sweep provides the most
effective and efficient tool to show the
effects and compromises of setting up
the correct gain versus frequency.
