Firmware changes log of IT-15T2 16.02.01 and 16.02.02 hardware

v15.0.0.10 of 29.08.2014

  • IT-15T2 hardware modification 16.2.2 supporting implemented: external amplifiers power supply 5V added
  • ECHO mode bug fixed: artef losing lock with DVB-T2 channel and relocking again, MER and constellation diagram were not measured

v15.0.0.9 from 16.04.2014

  • DVB-T2 channel MER measurement algorithm changed: MER accuracy increased in the long term echo reception conditions
  • DVB-T2 channel MER measurement range changed: 4…35 dB for QPSK, 10…35 dB for QAM16, 16…35 dB for QAM64, 22…35 dB for QAM256
  • Limit plan. Minimum allowable MER for DVB-T2 channel setting range changed: 4…35 dB for QPSK, 10…35 dB for QAM16, 16…35 dB for QAM64, 22…35 dB for QAM256
  • MER/BER, echo diagram. MER measuring during echo diagram measuring is disabled due to the new MER measuring algorithm requirements
  • Other non-critical bugs fixed.

NOTE! MER measuring duration for PLP streams of DVB-T2 channel with low bitrate increased, and may run up to several seconds.


v15.0.0.8 from 30.05.2013

  • Level beeping mode bug fixed: in some cases device was continuously beeping when left LEVEL mode;
  • Some English user interface's text messages changed;
  • Other non-critical bugs fixed.


v15.0.0.7 from 07.05.2013

  • preV-BER measurement range changed (5x10-2…1x10-6);
  • postV-BER measurement range changed (1x10-4…1x10-8);
  • Limit plan. Maximum allowable preV-BER setting range changed (1x10-3…1x10-6);
  • Limit plan. Maximum allowable postV-BER setting range changed (1x10-4…1x10-8).


v15.0.0.6

  • Initial revision.
