The SDA Family
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.
