COMMUNICATIONS TEST & MEASUREMENT SOLUTIONS
SDA-4040D
Stealth Digital Analyzer
Key Features
• Offers unmatched measurement performance in a single instrument • Enables easy preparation of networks for interactive services with a 5 to 1000-MHz fast, sensitive spectrum analyzer • Provides zero span measurement of power and carrier-tonoise ratios • Enables analysis and quality measurements of digital TV and cable modem signals with optional QAM analysis • Ensures full in-service proof of performance with automated tests • Reduces testing and troubleshooting times for network analysis and qualification • Rugged, weather-resistant, and lightweight
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 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, inservice 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 inservice testing for fastest return on revenue.

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.

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-tonoise 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.
