With today’s varied networks, a solution that can handle cable modems, digital
TV and maintain the analog spectrum is essential. Putting that solution into a
single, rugged instrument will enable technicians to use it in the most demanding
of situations, whenever it is needed.
The JDSU SDA-4040D Stealth Digital Analyzer is just such a solution. Detecting
and eliminating return path noise is accomplished with a fast spectrum analyzer
(detects signals down to a 5 µs duration), and the industry-unique JDSU
PathTrak™ Field View option. A zero span spectrum provides accurate, in-service
power and carrier-to-noise measurements of cable modems.
The new QAM View digital analysis option adds forward path digital signal testing
that includes constellation, pre/post FEC BER, MER, and an exclusive QAM in-
gress 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 autotesting.
The SDA-4040D is an ideal solution for any network. Priced competitively to
ensure that on-site technicians are fully equipped with the equipment they need,
the SDA-4040D will ensure rapid and accurate analysis of network turn-up or in-
service testing for fastest return on revenue.

troubleshoot difficult system problems
JDSU single-instrument solutions
The SDA-4040D Stealth Digital Analyzer delivers a single-instrument, “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 proven SAM
predecessor, the SDA-4040D 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 enables the
meter to be customized, or upgraded to the SDA-5000, to meet virtually any
system requirements.

Preparing the network for digital services
For measurement 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.
In addition, an exclusive QAM Ingress Noise mode enables 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.

In-service cable modem analyzer
For bursty digital signals such as TDMA technologies used on cable modems for
reverse services, the SDA-4040D offers two choices. The first is a one-button cable
modem analyzer and the second uses advanced zero span capabilities to make the
measurement. The one-button cable modem analyzer quickly shows carrier-to-
noise measurements, while the zero span option utilizes a time domain display to
enable power measurements while the modem is in service. Both methods are
compatible with global cable modem standards.
Making accurate digital average power measurements is addressed with the
digiCheck measurement function. The digiCheck feature is compatible with most
non-bursty digital modulations in use today (that is, 16, 32, 64, and 256 QAM,
QPR, QPSK, VSB, and CAP16).
Reverse digital modem signal
Analog and digital signal limits
Analog signal threshold limits have always been a technician’s favorite feature of
JDSU 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 capabilities
are available in both the Scan and Autotest modes.
PathTrak Field View option compares headend node
spectrum with field testpoint spectrum
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 technician simply uses markers to indicate the tilt chan-
nels that define the new limits.
Intermodulation distortion
Intermodulation distortion (CSO/CTB) can be automatically measured using the
CTB/CSO mode from the spectrum analyzer. CTB/CSO distortions produced by
intermodulation of analog TV carriers can degrade the signal quality of QAM
modulated signals used by digital video and cable modems.
Sweepless Sweep display
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.
Carrier-to-noise measurement: in-service
Carrier-to-noise measurement (on non-scrambled channels) is just as easy, and
there is no need to remove modulation from the video carrier. No tunable
preselector filter is needed.

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.
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.

SDA meters
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 desig-
nates which tests to perform on which channels. Because these tests are non-
intrusive, it is easy to test all parameters on all channels at any time.
After a test is performed, the results can be displayed on the SDA screen. A
pass/fail indication can be set on a variety of limits for FCC/CENELEC or other
government standards, or to system preferences. Data taken during any auto-
mated 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 single-channel level display shows both video and
audio levels (either single or dual sound/NICAM) and
the difference between the two
Data analysis with StealthWare
Any stored SDA measurement information can be uploaded to a PC using
StealthWare, a Microsoft® 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 in just the same way as on the actual
instrument. A sweep graph overlay function enables 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.
Digital channel average power measurements can be
made using the digiCheck™ feature
Upgrading the SDA-4040D to the SDA-5000
The JDSU upgrade program is designed to protect customers’ investment in test
equipment. As system requirements change, the SDA-4040D can be upgraded to
the SDA-5000 for forward and reverse sweep capabilities at any of JDSU
worldwide service centers, and model SAM-4040D owners can upgrade to the
SDA-4040D with an in-the-field firmware change only.
Tilt mode performs automatic tilt calculations
