Key Features
• Offers unmatched measurement performance for digital
video, data, and traditional analog services in a single
instrument
• Increases the efficiency of service calls and reduces
troubleshooting time
• Ensures HFC network integrity with the JDSU non-
interfering forward and reverse sweep system compatible
with today’s digital signals
• Enables easy preparation of networks for interactive
services with a 5 to 1000-MHz, fast, sensitive spectrum
analyzer
• Delivers comprehensive testing of forward and reverse
digital services including optional QAM analysis
• Ensures full in-service proof-of-performance with
automated tests
• Rugged, weather-resistant, and lightweight
In the world of high-growth subscriber services, engineers and technicians
struggle with assignments as diverse as tracking down and fixing ingress, aligning
optical nodes, and proof-of-performance. With competitive threats building,
cable operators need easy and cost-effective solutions for efficient installation,
qualification, maintenance and troubleshooting their HFC networks.
The JDSU SDA-5000 Series of Stealth Digital Analyzers provides a lightweight,
weather resistant, rugged, and affordable single instrument with the versatility to
test the latest digital services as well as the ideal device for maintaining the analog
spectrum. The SDA Series provides seamless forward and return path testing as
well as advanced digital testing. A host of invaluable extra options such as QAM
analysis and PathTrak Field View are available, enabling the SDA Series to be
customized for both the cable operator’s network technology level and budget.
The SDA builds on JDSU’s market leading RF sweep capabilities with numerous
new features that ensure engineers can cope with the changing demands of today’s
network.
Backward compatibility with earlier JDSU Stealth and StealthTrak Series products
build on a company’s existing investment. Automated testing, new “Find and Fix”
tools, and easy-to-use graphical user interfaces ensure training time is kept to a
minimum. In addition, users familiar with a JDSU Stealth product can transfer
their existing expertise to other SDA products without additional training.

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.
When maintaining and setting up the HFC network, the goal is to transmit all
signals with the best noise specifications and the lowest intermodulation distor-
tion. Sweep provides the most effective and efficient tool to show the effects and
compromises of setting up the correct 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 can be designated to an individual team or contractor and
tested to its own specifications and quality standards.
The SDA Series uses a variation of JDSU’s original market-leading 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 will not affect the sweep response measurement. The SDA-5500
transceiver has all of the measurement capability of the SDA-5000 receiver
enabling the technician to check headend levels.
The SDA Series also offers significantly faster forward sweep speed than earlier
instruments, especially in systems that include many digital signals. They can
reference 64/256 QAM signal types, removing the need to worry about subscriber
interference, or injecting sweep carriers in the guard bands.

Reverse sweep
The SDA-5000 (with option 1 installed) enables simple and practical testing of the
reverse path frequency response, regardless of the frequency (5 to 1000 MHz). It
has a built-in reverse sweep transmitter, which means externally generatedcarriers
are not required. Furthermore, the SDA-5500 transmitter and field receivers have
frequency agile telemetry, enabling them to communicate on both the forward
and reverse paths.
