Acterna - SDA-5510 - Analyzer
Sub Group:


The Stealth Digital Analyzer (SDA) cable network measurement tools test a wide range of critical parameters, helping you prove and maintain your system’s performance. Advanced features include tools to support preventative maintenance programs for improving network quality. Applications include aligning amplifiers such as optical nodes, testing the performance of both forward and reverse path networks, finding and fixing sources of reverse path ingress, measuring signal quality (both continuous and bursty digital carriers), and fulfilling FCC and CENELEC proof-of-performance requirements. You can perform comprehensive troubleshooting and preventative maintenance tests with accuracy and ease using Acterna’s SDA products: • Quickly check frequency response, signal levels, hum, carrier-to-noise (C/N) ratio, depth of modulation, and monitor the general performance of the cable system • Perform tests without interfering with CATV subscribers' service • Evaluate system performance precisely and diagnose and eliminate problems quickly to maintain quality operation of your CATV system equipment. Acterna’s Stealth Sweep System consists of at least two major components: a headend transmitter and a field receiver. SDA-5510 Stealth Reverse Sweep Manager The SDA-5510 is a standard 19" rack mount unit weighing approximately fifteen pounds. Its 320 X 240 dot matrix LCD shows measurement data in both graphical and numerical form. It is a full-featured signal analysis meter, with a complete spectrum display and an analog representation of single channel measurement data. When it’s tuned to a specific channel, comprehensive information is provided: • tuned channel • video frequency and level • audio frequency and level • differences between video and audio carrier levels. The SDA-5510 handles the reverse sweep job for up to 10 technicians. By adding the SDA-5510 to the Sweep System, you take responsibility for single-user reverse sweep away from the SDA-5500. This speeds the reverse sweep rate and increases the forward sweep speed. In addition, the SDA-5510 sends out reverse ingress/noise information with every update of its forward telemetry, so reverse telemetry need not be received to check the reverse ingress condition. Reverse Sweep Alignment Reverse sweep alignment provides an optimum view of the frequency response in the unoccupied reverse spectrum, leaving nothing to chance. A reverse sweep can uncover mismatch problems that reveal themselves as standing waves or as diplex filter roll-offs that can severely hamper the carriage of services in the reverse band. Ingress Detection and Troubleshooting The SDA-5510 provides feedback to the field about the current condition of noise and ingress in the headend. Even if the noise or ingress is swamping the telemetry, a picture of the headend noise/ingress is sent out for display to the receiver via a special forward telemetry carrier. Easy To Read Noise/Ingress Display The headend instrument continuously displays the noise/ingress performance of connected nodes, providing a quick, easy way for you to verify performance. In addition, the current reverse testing activity can be monitored. The SDA-5510 also performs essential cable TV system preventive maintenance tests with accuracy and ease. Reverse signal levels, hum, C/N, and frequency response can be quickly tested without subscriber interference.
