Atec Wavetek-JDSU-SDA-4040D - Manual

W hether deploying cable modems,
rolling out digital TV, or maintain-
ing the analog spectrum, the SDA-
4040D delivers precision "find and fix"
measurement tools that will reduce critical
test time when analyzing and qualifying
broadband network performance. Priced for
virtually any system budget, the SDA-
4040D brings unmatched measurement
performance to the network technician in a
rugged "One Box" solution. And with a ver-
satile upgrade program, the SDA-4040D
can be updated as technician skill levels
and system requirements expand.
Digital services testing is the centerpiece
of the SDA-4040D platform. Detecting and
eliminating return path noise is confronted
with a fast spectrum analyzer (detects sig-
nals down to a 5µs duration), and the
industry unique PathTrak Field View
option. A Zero Span spectrum provides
accurate, in-service power and carrier-to-
noise measurements of cable modems.
And the new QAM View digital analysis
option adds forward path digital signal
testing including constellation, pre/post
FEC BER, MER, and exclusive QAM Ingress
feature that reveals noise under an active
carrier. Of course, analog signal measure-
ments are addressed with standard fea-
tures like RF level, fast-scan, tilt, in-service
C/N and HUM, and FCC and CENELEC
compliant auto testing.
WWG also offers comprehensive technical
training programs to make sure that net-
work field technicians become experts on
the SDA-4040D. WWG training provides
detailed instruction on the time saving and
practical SDA-4040D applications related
to the latest broadband technology.
Preparing the Network
for Digital Services
QAM View Option Ensures Quality
Forward Path Digital Services. For mea-
surement and analysis of digital TV and
forward modem signals, the new QAM View
option provides a full complement of digi-
tal quality measurements. Included is a
64/256 QAM constellation display with
zoom, average digital power level, Bit Error
Rate (BER), 21 to 35 dB Modulation Error
Ratio (MER) and noise margin "cliff effect"
parameter. An equalizer display shows
equalizer stress and distance to fault.
! Constellation display with MER and pre/post
FEC BER.
In addition, an exclusive QAM ingress
noise mode allows technicians to see
ingress/noise under an active digital carri-
er. This tool is invaluable for detecting for-
ward path ingress otherwise hidden by
conventional spectrum views!
! QAM ingress feature shows noise/ingress
under an active carrier.
