Atec SDA-4040D User Manual

W

hether deploying cable modems,
rolling out digital TV, or maintain-

ing the analog spectrum, the SDA­4040D 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 SDA­4040D brings unmatched measurement
performance to the network technician in a
rugged "One Box" solution. And with a ver­satile 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 sig­nals down to a 5µs duration), and the
industry unique PathTrak Field View
option. A Zero Span spectrum provides
accurate, in-service power and carrier-to­noise 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 measure­ments are addressed with standard fea­tures 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 net­work 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 digi­tal 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 carri­er. This tool is invaluable for detecting for­ward path ingress otherwise hidden by
conventional spectrum views!

Measuring the Behavior of
DOCSIS/DAVIC Compatible Cable
Modem Signals in the Cable Plant. For

"bursty" digital signals, such as TDMA
technologies used on cable modems for
reverse services, the SDA-4040D uses the
advanced Zero Span capabilities to make
the measurement. Time domain displays of
TDMA signals allow power measurement,
D/U (desired/undesired measurements),
and detection of packet collisions, all while
the modem is in service. Technicians can
measure the level of interference in the
actual channel being used.

!Time domain view of ingress in the Zero Span

mode captures elusive ingress.

! Cable modem analysis using Zero Span mode

provides accurate, in-service, power and C/N
measurements.

Fast-Update Spectrum Display for
Detecting Ingress in the Field. The spec-

trum mode has the speed and versatility
to effectively troubleshoot difficult system
problems. A programmable dwell time
allows the meter to stay on each frequen­cy longer to catch more ingress. Peak hold
mode captures and saves transient bursts
(like evasive return path electrical noise).
The SAM4040D detects signals as fast as
5µs, in both Zero Span and continuous
modes. The pre-amp and low-pass filter
on the SDA-4040D assures that ingress
can be measured on devices with bi-direc­tional testpoints or testpoint values of
30dB or more.

! Reverse digital modem signal.

PathTrak Field View Option.

When your network is equipped

with the PathTrak Performance
Monitoring System, system technicians can
benefit from the ultimate ingress fighting
tool—the PathTrak Field View option for
the SDA-4040D. With Field View, the SDA­4040D receives a return path headend
spectrum broadcast from the PathTrak unit,
and then compares it with a return path
spectrum at any field testpoint. The side­by-side spectrum comparison instantly
reveals to the technician whether the
ingress source is originating at his current
testpoint or at a different location. The
comparative spectrum technique slashes
noise/ingress troubleshooting time, since
the technician can immediately verify
whether corrective action performed in the
field (local trace) results in improvement in
the headend spectrum (remote trace).

! PathTrak Field View option compares headend

node spectrum with field test-point spectrum.

Sweepless Sweep® Provides Non­Intrusive Frequency Response.

The trade­marked Sweepless Sweep® passively pro­vides frequency response information
about a network by measuring active carri­ers. The SAM404D stores the levels of all
active carriers at one reference point in the
network, and then compares the relative
levels to another point within the network;
just like referenced sweep, but without the
need for a transmitter!

! 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, sum­mary displays. The graphics present the
information the way the technician wants
to see the results – no further interpreta­tion required. For example, testpoint com­pensation values are entered at the start of
testing. Displays then calculate actual lev­els 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 conven­tions are used across all product families.
The learning curve for a progressing techni­cian is considerably shorter than alterna­tive 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 prov­ing, and improving, network quality. All
tests utilize a practical user interface, nor­mally 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 techni­cian’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 specifi­cations. 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 ser­vices in the HFC network.
With the same durability
and measurement accura­cy as its venerable SAM
predecessor, the SDA­4040D is designed with
the speed, spectrum and
advanced QAM analysis to
test both traditional ana­log video and the latest
digital formats. The versa­tile combination of stan­dard features and avail­able options allow the
meter to be customized,
or upgraded to the SDA­5000, to meet virtually any
system requirements.

Measurement

Tilt Measurement. Tilt is the
easiest and most efficient tool

for balancing amplifiers. For
cable plants requiring multiple tilt mea­surements, such as comparing today’s tilt
measurement with a historical record, and
then making an additional measurement
for a new wider channel plan, the user sim­ply uses markers to indicate the tilt chan­nels that define the new limits.

! Tilt mode performs automatic tilt calculations

between any 2 of 9 designated carriers.

The CTB/CSO mode is used for

automatically making intermod-

ulation measurements.

Scan Measurement. Scan

mode provides a quick graphical

view of the entire channel plan
with bars representing the video level for
each channel. Both video and audio may
be displayed.

! Limit checks can be instantly viewed after

identifying channel of interest with a marker in
scan mode display.

Carrier-to-Noise Measurement:

In-Service. Carrier-to-noise

measurement (on non-scram-

bled channel) is just as easy,
and there is no need to remove modula­tion from the video carrier. No tunable pre­selector filter is needed.

! In-service carrier-to-noise.

Hum Measurement: In-Service.

Measuring hum on a channel

(non-scrambled) is as simple as
pressing the "HUM" key. And since the
instrument is battery powered, the measure­ment is independent of ground loops, there­fore isolated from the line (mains). Hum
reveals itself as either single (60 Hz) or dou­ble (120 Hz) horizontal bars across the video
screen. The level of either can be measured.

! In-service HUM (PAL & NTSC compatible).

Modulation Measurement.

Includes NTSC, PAL and SECAM

formats. Demodulation of the
audio is done for both AM and FM. FM is
used to hear audio distortion on the FM
radio channels or the sound of the TV pro­gram. AM is used to recognize short-wave
interference signals in the reverse band.

! Depth of modulation.

Extensive Automated
Test Capability

Automated tests can be scheduled to per­form either 24-hour FCC compliance tests,
or initiated immediately to log performance
at individual nodes, amplifiers, or other
testpoints. A wide range of tests can be
performed automatically, including signal
levels, C/N, hum, and depth of modulation.
The operator designates which tests to per­form on which channels. Because these
tests are non-intrusive, it is easy to test all
parameters on all channels at anytime.

After a test is performed, the results can be
displayed on the SDA screen. A pass/fail
indication on a variety of limits can be set
for FCC/CENELEC or other government
standards, or to system preferences. Data
taken during any automated test, or
sequence of automated tests, can be
viewed immediately with a pass/fail indica­tion for each of the limits. Specific stored
measurement results may be viewed on
demand. Automated test results can be
printed directly to a serial printer or
uploaded to a PC using StealthWare to
store and include in custom reports.

! The detailed scan graph offers user-adjustable

marker, scale reference level and tilt for maxi­mum signal evaluation.

Data Analysis with StealthWare. Any
stored SDA measurement information can
be up-loaded to a PC using StealthWare, a
Windows™ based data management pack­age. Stored sweep, scan, or spectrum
screens can be viewed on the PC and ana­lyzed with marker movement and readout
information just the same as on the actual
unit. A sweep graph overlay function
allows comparison of multiple RF response
variations over time. StealthWare also
allows the operator to build channel plans
and edit site locations, which can be
downloaded to multiple SDA instruments.
Additionally, channel plans can be
uploaded to the PC, modified in
StealthWare, and then downloaded back to
the SDA instrument.

Upgrading the SDA-4040D to SDA-5000.
