Przenośny wielofunkcyjny analizator sieci HFC
The 860 DSPi is a cable analyzer and CATV meter that performs transmission and signal quality tests for analog and digital HSD and VoIP services. Fast and powerful, Trilithic's popular 860 DSPi offers a versatile solution for your changing business needs.
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.
Thanks to DSP technology, you can update or upgrade your 860 DSPi with a simple Internet download - anytime or anywhere. Your techs can change with the times - or with new services - without changing meters, which can change your bottom line. No other meter gives you lower lifetime costs.
The 860 DSPi can be easily upgraded 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.
This option builds in a CableLabs® certified DOCSIS 3.0 modem, enabling a full complement of DOCSIS 3.0 tests.
The Wi-Fi option builds in a Wi-Fi (802.11 b/g) adapter, enabling a full complement of Wi-Fi network verification tests.
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.
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.
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, 4 - 1000 MHz. 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)
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.
