! Sweepless Sweep® Display.
Powerful Graphic
Displays and Common
User Interface Allows
Technicians to Learn Fast.
The results of all measurements
are presented to the user in
clear, highly informative, sum-
mary displays. The graphics present the
information the way the technician wants
to see the results – no further interpreta-
tion required. For example, testpoint com-
pensation values are entered at the start of
testing. Displays then calculate actual lev-
els automatically, minimizing field errors.
! Graphical reverse testpoint compensation.
With SDA series products, all levels of
instruments are familiar to the technician,
regardless of which is learned first,
because the same user interface conven-
tions are used across all product families.
The learning curve for a progressing techni-
cian is considerably shorter than alterna-
tive test equipment. This means urgent
upgrade projects make the most efficient
use of limited resources when SDA series
products are used.
! The Navigator user interface, common on all
WWG meters.
Comprehensive Testing
The SDA-4040D provides an extensive set of
signal analysis features designed for prov-
ing, and improving, network quality. All
tests utilize a practical user interface, nor-
mally requiring only a one-button keystroke.
Level Measurement. The SDA
instruments provide a comprehen-
sive single-channel display with
tuned channel, video frequency and level,
audio frequency and level, and the difference
between video and audio carrier levels.
! The single-channel level display shows
both video and audio levels (either single
or dual sound/NICAM) and the difference
between the two.
! Digital channel average power measurements
can be made using the digiCheck™ feature.
Making accurate digital average power
measurements are addressed with the
digiCheck™ measurement function. The
digiCheck™ feature is compatible with
most "non-bursty" digital modulations in
use today (i.e., 16, 32, 64, and 256 QAM,
QPR, QPSK, VSB, CAP16, etc.).
Analog and Digital Signal
Limits. Analog signal threshold
limits have always been a techni-
cian’s favorite feature of WWG instruments.
Automatic limit checks provide a quick
go/no-go status for audio and video levels.
The SDA series extends this capability with
a dedicated digital limit set that can be
applied exclusively to the forward digital
carriers defined in a channel plan. By
assigning separate analog and digital limits,
test time is reduced since no calculation is
necessary to determine if analog and digital
level relationships are within system specifi-
cations. Analog and digital limit capability
is available in both the scan and autotest
modes (available July 2000).
WWG "One Box"
Solutions
The SDA-4040D signal
analysis meter delivers a
“One-Box" solution to
help deploy and maintain
quality video and data ser-
vices in the HFC network.
With the same durability
and measurement accura-
cy as its venerable SAM
predecessor, the SDA-
4040D is designed with
the speed, spectrum and
advanced QAM analysis to
test both traditional ana-
log video and the latest
digital formats. The versa-
tile combination of stan-
dard features and avail-
able options allow the
meter to be customized,
or upgraded to the SDA-
5000, to meet virtually any
system requirements.
