Check the listing for details. Multifunction Interactive Cable Analyzer | Trilithic 860DSP W/15V 2A (QTY:5). Condition: Used. Listed at 300.00 USD. 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.FrequencyRange5 MHz-1 GHzAccuracy@25° C +/-0.75 dB Over temp (-18 to +50° C): +/-2.0 dB (Analog), +/-2.5 dB (Digital)Resolution0.1 dBCarrier-to-Noise (In-service, non-scrambled standard channels only)Min Input Level for Full Range+10 dBmVDynamic Range50 dBResolution< 0.5 dBHum (In-service, non-scrambled standard channels only)Minimum Input Level0 dBmVRange0 to 5%Resolution0.1%Accuracy+/- 0.5%Depth of Modulation (In-service, non-scrambled standard channels only)Range50 to 100%Resolution0.5%Audio DemodulationFM CarriersTiltMax Number of Carriers10Hi / Lo Delta Resolution0.1 dBScanVideo, Audio, Pilot, and Digital Carriers; includes total power measurementForward (Sweepless) Sweep ModeFrequency Range4 MHz to 1 GHzDisplay SpanUser definableDisplay Scale1, 2, 5, or 10 dB/divisionDisplay Range6 vertical divisionsSweep Rate (78 channels)~ 500 msSpectrum ModeSpansUser selectable in 10 kHz stepsDisplay Scale1, 2, 5, or 10 dB/divisionRange7 vertical linesDetection & DwellSelectable Detector Modes (Narrow or Wide) and Dwell TimeSpurious Free Dynamic Range60 dB @ 25° C (+50 dBmV)Sensitivity-40 dBmV (5 MHz to 1 GHz)Zero Span ModeVideo BandwidthDigital averagingResolution Bandwidth10, 30, 100, & 300 MHz; 1, 3 MHzPulse Measurement AccuracyNominal level in < 7 ms, +/- 2 dB for nominal in 4 ms (300 kHz RBW)Sweep Times50 ms to 20 sec in 1, 2, 5 settingsIntermodulation Distortion (CSO/CTB)Range= 60 dBResolution0.1 dBQAM MeasurementsModulation TypesITU J.83 Annex A, B, C QPSK, 16, 32, 64, 128, & 256 QAM(at symbol rates from 2 MSPS to 6.9 MSPS)Measurable Input (Lock) Range64 QAM: -20 to +50 dBmV (typical) 256 QAM: -15 to +50 dBmV (typical)Frequency Tuning5 MHz to 1 GHzBER (64 & 256 QAM, pre & post FEC)10-4 to 10-9MER64 & 256 QAM, 6 MHz Channel Bandwidth: Range: 21 to 38 dB, Accuracy (typical): ±1.5 dB64 & 256 QAM, 8 MHz Channel Bandwidth: Range: 21 to 35 dBAccuracy (typical): ±2.0 dBEVM64 QAM, 6 or 8 MHz Channel Range: 1.1% to 8.1% Accuracy: ±0.5% (1.1 to 2.0%) ±1.0% (2.1 to 4.2%) ±1.6% (4.3 to 8.1%)256 QAM, 6 or 8 MHz Channel Range: 1.1% to 5.3% Accuracy: ±0.5% (1.1 to 2.0%) ±0.8% (2.1 to 4.2%)QAM Level MeasurementSignal TypesQPSK; QAM (16, 32, 64, 128, & 256)Range-40 to +50 dBmVAccuracy @ 25° C+/- 1.25 dBPower SourceCharging Time4 HoursOperating Time, Continuous Use~4 hoursPhysicalWeight4.75 lbs.Operating Temperature Range-18 to +50° C (0 to 122° F)
