860 DSPi
Digital Installation Analyzer
You need to enable JavaScript to view the Flash movie.
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.
Key features
- Test DOCSIS, cable modem performance and VoIP quality analysis
- 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
NOW featuring 1GHz capabilities!
Here are just a few of the latest additions to this evergreen product:
-
QAM Source Mode
This is one means for verifying the transmission capability of a particular segment of the network for higher order QAM signals. Many cable systems have stepped from QPSK to 16 QAM and now are moving to 64 QAM for upstream data transmission. -
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. -
8 VSB and 16 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 and 16 VSB channels. -
High speed Throughput
This option allows the technician to test upstream data paths up to 10 Mbps and downstream data paths up to 40 Mbps. 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 (USG)
Provides periodic grants for an upstream service flow without the need for a cable modem to transmit bandwidth requests.
The 860 DSPi also features:
-
Analog, QAM Signal Analysis
Measures Amplitude, MER/BER, EVM, Equalizer settings. With option displays Constellations. -
Modem Performance Tests
Test all digital parameters affecting HSD performance. Includes Ping and Throughput tests. -
VoIP Quality Analysis
One-button test sequence for Lost/Discarded Packets, Latency, Jitter. Automatically calculates MOS. Tests to the CMTS, Tests to a target Server. -
High Resolution Spectrum Analysis
Detects and identifies ingress sources, 5 - 1 GHz. Resolution selectable from 10 kHz - 3 MHz (with Option) -
Reverse Path Setup and Evaluation
Displays Ingress spectrum from Headend, compares with local ingress, displays return Tilt and Gain (with option). Performs automated installation testing of Upstream Transmit Levels and C/I, from sub to Headend (with Option). -
Internet Browser and Server Functions
Browses Internet information sites, up/downloads work orders, functions as a browsable server for remote operation (with Option)
Note: Technicians who do not maintain DOCSIS services and/or do not need a modem-equipped field analyzer may want to choose the 860 DSP analyzer.
VITS
With the VITS option, headend technicians can view Vertical Interval Test Signals (VITS), which are inserted during the vertical synchronization interval of analog video, and specify lines for testing. The option enables the technician to measure differential phase, differential gain, chroma delay.
