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 testing 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.


  • lightweight and compact handheld design
  • measurement modes:
    • BER/MER mode performs measurements of DVB-T/T2 channels, shows the measurement results on a bar-graph, constellation and echo diagrams
    • SPECTRUM mode provides scanning of entire band with the span defined by user from 18 to 72 MHz
    • SCAN, TILT and RIPPLE modes shows the level of all the channels present in the band (or channels according to the channel plan) on a bar-graph
  • 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
  • measurement of reception quality parameters of digital channels:
    • modulation error rate (MER)
    • bit error rate before (preVBER) and after (postVBER) Viterbi decoder, and also number of erroneous packets after Reed-Solomon decoder for DVB-T channels
    • bit error rate before (preLDPC) and after (postLDPC) LDPC decoder, and also number of erroneous packets after ВСН decoder for DVB-T2 channels
    • channel carrier frequency offset from the tuning frequency
    • echo measurements
  • Data logger storing:
    • up to 32 channel plans (with channel names). Automatic channel plan creation. Automatic search for digital channel modulation parameters
    • up to 130 measurement logs (each indicating channel levels, C/N and V/A ratios), checking the parameter against the limit plan and saving measurement date and time. For digital channels, channel power, C/N ratio, BER, and MER are measured
    • up to 130 spectrum analyzer logs with 125 kHz step, adjustable scanning span and saving measurement date and time.
  • measurement of DC input voltage within the range of 10 to 100 V
  • external devices (amplifiers, etc.) powering over input connector
  • operation with PC (additional modes avaliable)
  • MC-089 Removable Module is only compatible with the upgraded MB-08 Base Unit (with color display)
