IT-087 DVB-C Signal Analyzer

IT-087 KEY FEATURES:

• • lightweight and compact handheld design

  • measurement modes:

    • BER/MER mode performs measurements of DVB-C channels and shows the results on a bar-graph or a constellation diagram

    • SPECTRUM mode provides scanning of the entire band with the span defined by the user from 18 to 72 MHz

    • SCAN, TILT and RIPPLE modes show 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 (BER) before and after Reed-Solomon decoder

    • channel carrier frequency offset from the tuning frequency

  • data logger storing:

    • up to 32 channel plans (with channel names) and automatic channel plan creation. Automatic search for digital channel modulation parameters

    • up to 130 measurement logs (each showing 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.

  • analog channels audio reproduction with built-in speaker

  • measurement of AC/DC input voltage within the range of 10 to 100 V

  • operation with PC (additional modes available)

PC SOFTWARE ViewIt08C ALLOWS:

• • performing all kinds of measurements

  • viewing and saving data logs

  • editing channel plans

  • saving and documenting measurement results
