- Test DOCSIS, cable modem performance and VoIP quality analysis
levels
- DSP technology for quick, accurate measurements and high tech
productivity
- Internet browser and server functions integrate with OSS and Workforce
Management
- Large, easy-to-read display and simple user interface for shorter learning
curve
- Efficient design for long battery life – up to five times that of
competing instruments
- Adaptable platform grows to meet the needs of technicians at every
tier
- The high-performance portable analyzer for the digital age.
- Now you can use a single instrument for all the critical transmission and
signal quality tests you need to install and maintain analog, digital, HSD and
VoIP services – without the pauses and boot-up delays of other field
analyzers.
You can also easily upgrade the 860 DSPi for new applications – right in the
field – or add powerful options like high-resolution spectrum analysis, QAM and
QPSK constellation displays and a wide range of return path tests, all without
impacting size or weight. TraffiControl Feature Enables troubleshooting ingress
and impulse noise within an active upstream channel band. QAM Source Mode This
is one means for verifying the upstream transmission capability of a particular
segment of the network for higher order QAM signals, up to 64 QAM. Many cable
systems have stepped from QPSK to 16 QAM and now are moving to 64 QAM for
upstream data transmission. 8 VSB functionality This optional feature allows the
operator to connect an off air antenna to the 860 DSP input port and read level,
MER, BER, and view constellation and equalizer tap information on 8 VSB
channels. High speed Throughput This option allows the technician to test
upstream/downstream data path throughput to the full range of the bonded
channels. This is a valuable tool for verifying provisioning as well as
bandwidth availability at customer homes or at key test points in the system.
Unsolicited Grant Service (UGS) Provides periodic grants for an upstream service
flow without the need for a cable modem to transmit bandwidth requests. Advanced
CSO / CTB in-channel functionality Enables in-service testing when used with a
3rd party Line Blanker. Line Viewer Utility This is feature that can be used to
verify the line blanking.
