DSAM-3600B
The Acterna DSAM is a high-speed data installer meter that increases the
number of cable modem installs per day. Using exclusive digital signal
processing and integrated DOCSIS/EuroDOCSIS chipset technology, the meter
communicates with the network CMTS to verify suitable conditions for cable modem
installation from the subscriber's location. The DSAM is also equipped with
signal level meter capabilities, including spectrum scanning for ingress
assessment and mini-scan analysis of up to twelve analog and/or digital
channels. The meter's AutoTest capability makes installations easier and more
reliabe than ever before.
Highlights
- All-in-one meter includes DOCSIS/EuroDOCSIS service testing and SLM
features.
- Autotest capability with administration security.
- Environmental resilience and robustness.
- Extensive help system directly linked to meter capabilities.
- Multiple language support.

SDA-5000 Installed Options:
The SDA-5000 is used for HFC network testing and
deployment of digital video, data, and traditional analog services. It is part
of a system sweep solution. The SDA-5000 is a small, lightweight hand-held field
CATV Sweep Analyzer for diagnosing and eliminating problems quickly in CATV
system equipment. Ideal for aligning amplifiers, testing performance of both
forward and reverse path networks, finding and fixing sources of reverse path
ingress, measuring signal quality, and fulfilling FCC and CENELEC
proof-of-performance requirements.
Highlights:
- Qualifies the network for today's high-growth subscriber services.
- Reduces technician time for the most labor intensive maintenance and
troubleshooting.
- Advanced QAM analysis for 64, 128, and 256 QAM (optional).
- Spectrum display from 5 to 1,000 MHz with cable modem analysis (Zero Span
mode).
- Totally non-interfering sweep, specifically for 64, 128, and 256 QAM
digital channels.
Applications:
- Non-interfering, continuously referenced sweep.
- Cable modem analysis using Zero Span mode.
- Full in-service, proof-of-performance analyzer.
- QAM View option provides complete analysis of digital TV and forward cable
modem signals.
- Find ingress fast with Field View option. Cable technicians working in the
field can see the reverse path at the headend.
Key
Features:
- Forward and reverse sweep in one handheld instrument.
- QAM View includes BER, MER, and constellation.
- Equalizer stress and microreflections.
- QAM ingress (noise-under-carrier).
- New graphical test point compensation for easier setup
