The Stealth Digital Analyzer (SDA) product
family offers a true "One Box" solution for
HFC network testing and deployment of digital video, data, and traditional analog services.
While preserving the rugged design and
industry standard RF sweep technique of its
Stealth Sweep System predecessor, the SDA
series now adds test features to qualify the
network for today’s high growth subscriber
services. "Find and Fix" tools are included
that reduce technician time for the most labor
intensive maintenance and troubleshooting
assignments, like tracking down reverse
ingress, optical node alignment, proof-of-performance testing, and return path alignment.
For these demands, the SDA provides
advanced QAM analysis (optional), a powerful 5 to 1,000 MHz spectrum display with
cable modem analysis (Zero Span),
PathTrak™ Field View, and full forward and
reverse sweep capability. And with the versatile combination of standard and optional
features, the SDA can be customized for both
the cable operator’s network technology level
and budget.
Why Sweep is the
Right Solution
The majority of all transmission
errors (including digital) are found
by measuring 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.
The goal is to transmit all signals with the best
noise specifications and the lowest intermodulation distortion. Sweep is the most effective and
efficient tool to show the best compromise
between the two. In other words, sweep helps
technicians setup the right gain versus frequency.
Normalized Sweep
To ensure that network specifications are
maintained, starting from the headend to the
subscriber, each section of the network has its
own set of specifications. A normalized sweep
divides the network into easily managed sections. Each of these network sections, with its
own set of specifications and quality requirements, can be designated to an individual
team or contractor.

The SDA series uses a variation of the original Stealth Sweep
technology. Existing video carriers (analog, digital, or scrambled) are referenced when possible, eliminating any possibility
of interference to the subscriber services. Where carriers are
absent, the SDA-5500 Transceiver at the headend transmits a
sweep to fill vacant spectrum areas. To remove effects of
headend level drift, the SDA-5500 Transceiver monitors the
levels and transmits new reference information with every
sweep. This means that if the signal levels are changing in the
headend, they won't effect the sweep response measurement.
The SDA-5500 Transceiver has all of the measurement capability of the SDA-5000 Receiver, therefore the Headend
Technician can keep an eye on headend levels.
The SDA series also offers significantly faster forward sweep
speed, especially in systems that include many digital signals. The SDA is capable of referencing 64/256 QAM signal
types, so there is no need to worry about subscriber interference or injecting sweep carriers in the guard bands.
Stealth Sweep and SDA Series
Sweep Compatibility
The SDA series is completely sweep compatible with Stealth
3SR, 3ST, 3HRV, and StealthTrak SSA-1000 series meters.
The only requirement is that firmware version 9.3 is
installed in Stealth meters, and firmware version 2.0
installed in StealthTrak SSA-1000 meters. To take full
advantage of the faster forward sweep capability, all headend and field instruments must be SDA series.
Preparing the Network for
Interactive Services
Reverse Sweep
The SDA-5000 (with OPT 1 installed) allows simple and
practical testing of the reverse path frequency response,
regardless of the frequency (5 to 1000 MHz). And the SDA
has a built-in reverse sweep transmitter, which means externally generated carriers are not required. Furthermore, the
SDA-5500 transmitter and field receivers have frequency
agile telemetry. They can be configured to communicate on
both the forward and reverse paths.
Forward (downstream) and reverse (upstream) path alignment can be performed simultaneously by one person. The
operator simply indicates which screen should be displayed—the response from the headend to the test point, or
the response from the test point to the headend. A reverse
sweep can uncover mismatch problems, which reveal themselves as standing waves, or duplex filter roll-offs that can
severely hamper the quality of services in the reverse band.
Multiple User Reverse Testing
For intense reverse testing requirements, the rack mounted
Model SDA-5510 Headend Reverse Sweep Manager handles
the reverse sweep job for up to ten different technicians on
the same cluster of nodes. Using the SDA-5510 in conjunction with the model SDA-5500 Transceiver provides a full
forward and reverse sweep alignment solution. The SDA5510 can also stand alone in remote hub sites for dedicated
reverse alignment applications.

Portable Reverse Sweep Manager
The portable version of the SDA-5510 allows technicians to
install a multiple user Reverse Sweep Manager in locations
where it is not practical to install a rack mount unit. The
SDA-5000 with OPT 6 provides all the functionality of the
SDA-5510, but in the rugged SDA-5000 field unit package.
Applications include installation in systems where reverse
traffic is received by an ATM/SONET/SDH network rather
than returning to the headend, or any condition that prevents rack mount installation or access to a headend/hub
site (Note: Forward sweep capability not included with
SDA-5000 with OPT 6).
Seeing Headend/Hub Site Accumulated
Ingress in the Field
The reverse noise feature of the SDA-5000 enables easy
reverse path noise testing. The operator simply presses the
"Noise" soft key while reverse sweeping, and the display
changes to a noise/ingress response indicating the noise
level over the entire reverse path spectrum measured at the
headend or hub site. All SDA Transmitters provide feedback
to the field regarding the current condition of noise and
ingress in the headend, even when noise or ingress is
"swamping" the telemetry (broadcast mode). A "picture" of
the headend noise/ingress is sent out to the SDA Receiver
via a special forward telemetry carrier.

QAM View Ensures Quality Forward Path
Digital Services
For measurement and analysis of digital TV and forward
modem signals, the new digital 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 a noise margin
"cliff effect" parameter. An equalizer display shows equalizer
stress and distance to fault.

In-Service Cable Modem Analyzer
For "bursty" digital signals such as TDMA technologies
used on cable modems for reverse services, the SDA-5000
offers two measurement choices. The first, a one-button
cable modem analyzer test, quickly shows carrier-to-noise
measurements. The second, an advanced Zero Span feature,
utilizes a time domain display to allow power measurements while the modem is in service. Both methods are
compatible with global cable modem standards.

Detecting Ingress in the Field
The operator looks at the ingress present at the field test point
using the spectrum display on any of the receivers, then
switches to reverse ingress/noise to see the ingress at the headend for comparison. This time-saving procedure helps in
locating sources of ingress. An adjustable dwell time ensures
that even intermittent ingress is detected. The preamp and
low-pass filter also assures that even low-level ingress is seen.
The preamp and low-pass filter on the SDA-5000 assures that
ingress can be measured on devices with bi-directional testpoints or testpoint values of 30 dB or more.

PathTrak Field View
When a system 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-5000. With Field View, the SDA-5000
receives a return path headend spectrum broadcast from the
PathTrak unit and compares it with a return path spectrum
at any field testpoint. The side-by-side spectrum compari-
son instantly reveals to the technician whether the ingress
source is originating at the 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).

Powerful Graphic Displays and
Common User Interface Allow
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.

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 (several examples of the icons
are included in this literature). The learning curve for a
progressing technician is considerably shorter than with
alternative test equipment. This means urgent upgrade projects make the most efficient use of limited resources when
SDA series products are used.

Comprehensive Testing
The SDA 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 the push of a button.
Level Measurement
The SDA instruments have a comprehensive single-channel
level display that indicates tuned channel, video frequency
and level, audio frequency and level, and the difference
between video and audio carrier levels.

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 (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 Acterna 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.
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 taking an additional measurement for a new wider channel plan, the technician simply
uses markers to indicate the tilt channels that define the
new limits.

Carrier-to-Noise Measurement: In-Service
Taking carrier-to-noise measurements (on a non-scrambled
channel) is easy. There is no need to remove modulation from
the video carrier, and a tunable preselector filter is not needed.

Hum Measurement: In-Service
Measuring hum on a channel (non-scrambled) is as simple as
pressing the "HUM" key. Since the instrument is battery powered, the measurement is independent of ground loops and is,
therefore, isolated from the line (mains). Hum is revealed as as
either a 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 shortwave interference signals in the reverse band.

Local AmplifierAlignmentw/Loopback Tests
The SDA loopback tests allow the technician to quickly perform frequency response measurements of active or passive
field devices using a single meter. Either a CW or sweep signal may be generated from the SDA unit and injected to the
input of a device under test. The DUT output can then be
measured by the SDA, providing valuable information such
as gain, loss, roll-off, or frequency response. The CW loopback test is available on the SDA-5000 when ordered with
OPT 1. The CW loopback and sweep loopback features are
available on the SDA-5000 when ordered with OPT 2.

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.

Data Analysis with StealthWare
Any stored SDA measurement information can be uploaded 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. Old sweep graphs may be downloaded
back into the SDA instrument for real-time comparison.
“One Box” Solution
How many test instruments should the network maintenance technician carry? One. A lightweight, rugged, and
affordable meter with the versatility to test the latest digital
services while maintaining the analog spectrum. This "One
Box" philosophy shaped the design of the SDA series, adding
the analog and digital test tools most requested by field technicians and system operators throughout the world.
