IT-089 DVB-T/T2 Signal Analyzer

 

   IT-089 DVB-T/T2 Signal Analyzer is a configuration of the IT-08 Multifunction TV Meter comprised of MB-08 Base Unit and MC-089 Removable Module. IT-089 is designed to ensure high-performance control and adjustment of television and broadcasting distribution networks as well as of separate components of such networks, or other electronic devices. The Analyzer allows measurement of DVB-T/T2 signal parameters and analog signals. IT-089 is capable to satisfy your measurement needs for high-quality operation within the range of 45 to 865 MHz.

 

 

 

 

IT-089 GENERAL FEATURES:

 

o   Lightweight and compact handheld design

o   Measurement modes:

·         BER/MER mode performs measurements of DVB-T/T2 channels, indicates measurement results on a bar-graph or a constellation diagram

·         SPECTRUM mode provides scanning of entire band with the span of 18, 36, or 72 MHz

·         SCAN, TILT and RIPPLE modes indicate the level of all the channels present in the band (or channels according to the channel plan) on a bar-graph

o   LEVEL measurements:

·         for analog channels: channel level, Carrier to Noise (C/N) ratio, Video to Audio (V/A) ratio

·         for digital channels: channel power, Carrier to Noise (C/N) ratio

o   Measurement of reception quality parameters of digital channels:

·         modulation error rate (MER)

·         bit error rate before (preVBER) and after (postVBER) Viterbi decoder, and also after (postBER) Reed-Solomon decoder for DVB-T channels

·         bit error rate before (preLDPC) and after (postLDPC) LDPC decoder, and also after (postBCH) BCH decoder for DVB-T2 channels

·         channel carrier frequency offset from the tuning frequency

·         echo measurements

o   Data logger function providing storage for:

·         up to 32 channel plans (with channel names). Automatic channel plan creation. Automatic search for digital channel parameters (modulation type, symbol rate)

·         up to 200 measurement logs (each indicating channel levels, C/N and V/A ratios), checking the parameter compliance with the limit plan and saving comments and measurement date and time. For digital channels, channel power within bandwidth, S/N ratio, BER, and MER are measured

·         up to 200 spectrum analyzer logs with 125 kHz step, adjustable scanning span and saving comments and measurement date and time. Saving up to 14 spectrum logs within the full frequency range

o   Measurement of AC/DC input voltage within the range of 10 to 100 V

o   External devices (amplifiers, etc.) powering over input connector

o   Operation with PC for access to additional modes:

·         performing all kinds of measurements and displaying results on the PC screen

·         viewing and editing data logs

·         updating software and firmware
