Description:

Deviser DS2500Q,1000MHz Digital TV QAM Spectrum analyzer catv meter 

 

 

Key Benefits

 

• High Speed Spectrum Analysis: 4~1000MHz

• Integrated DOCSIS 3.0 Cable Modem

• Integrated Upstream Signal Generator (no FEC)

• Supports ITU--T J.83 Annex A/B/C

• Error Vector Spectrum: identifies interference signals under QAM carriers, with no break in service

• Auto Test

 

Integrating multiple functions in a single handheld instrument, the new DS2500Q is a powerful Digital TV QAM Analyzer with a comprehensive measurement suite specifically designed for HFC network testing, troubleshooting, and maintenance.

 

The DS2500Q's main functions include Enhanced Spectrum 

Analysis, Analog & Digital TV analysis, DOCSIS 3.0 analysis,

Upstream Signal Generator, Ethernet testing, and Auto Test. The revolutionary EVS function enables users to detect coherent distortions hiding under QAM carriers - without interrupting service. The DS2500Q supports Deviser's PC software toolkit, included with each unit, to make data transfer a snap.

 

High-Speed Spectrum Analysis

 

The DS2500Q offers enhanced spectrum analysis performance

with a frequency range of 4MHz ~ 1000MHz and sensitivity to signals as low as -55dBmV (@300KHz).

The DS2500Q also offers Digital HUM distortion measurement, from the fundamental frequency to 4th harmonic components.

The spectrogram provides a scrolling three-dimensional display, allowing users to track frequency and level over time - excellent for analyzing intermittent signals.

 

DVB-C Signal Analysis

 

The DS2500Q supports the ITU-T J.83 Annex A/B/C standard, providing Channel Power, MER, BER, Constellation, and Digital HUM measurements.

EVS In-service Interference Detection

The Error Vector Spectrum feature can find interference signals under a QAM carrier without service interruptions.

Upstream Signal Generator

The Upstream signal generator can generate a CW carrier or a QAM signal. A sweeping mode is also available.

 

Cable Modem Measurement

 

The DS2500Q incorporates a standard DOCSIS 3.0 cable modem, compatible with DOCSIS 1.X, 2.0 & 3.0. The built-in modem supports 8x DS and 4x US bonded carriers. Figure 8 (below) shows the CM statistical info screen - including downstream signal level, modulation type, bandwidth, symbol rate, MER, BER, upstream signal level, symbol rate, & UCD (Upstream Channel Descriptor). Users can select the desired DOCSIS mode, downstream channel, and UCD. Basic network test tools include Ping, Traceroute, PPPoE, FTP, and Browser.

 

Auto Test

 

The DS2500Q comes equipped with a wide range of region-standard channel plans spanning (in part) North America, Asia, and Europe, as well as several sets of limit profiles - allowing users to design automatic tests. Tasks that can be automated include Analog TV, Digital TV and Cable Modem testing. Once the analyzer completes an auto test, all items in the test results will indicate Pass or Fail according to the limit profile. Results are automatically saved for later analysis.
