  • Other non-critical graphical user interface bugs fixed

it088_build_130103.bsk2 from 03.01.2013
Operating system: v1.2.0.10
Application: v1.2.0.6

  • Channel plan automatic detection bug fixed: in some cases channel modulation type (digital or analog) detected incorrent in SCAN mode, channel plans manager when creating a new channel plan, and in operation with ViewIt08C software
  • Digital channels MER and BER parameters measurement bug fixed: for channels with high level (100 dBuV or higher) MER and BER values could have been worse than real ones
  • Digital channels MER and BER parameters measurement performance improved: for some frequency points in 5...900 MHz range MER and BER values could have been worse than real ones
  • Signal to noise ration measurement accuracy risen: the value was 2...3 dB higher than the real one
  • Spectrum data logger bug fixed: spectrum measurement was inaccurate due to the incorrent attenuator set
  • Spectrum data logger bug fixed: firmware crashed when viewing spectrum of the measured page
  • Spectrum data logger bug fixed: spectrum of the measured pages displayed incorrect with ViewIt08C software
  • Checking channel data logger page with limits bug fixed: checking page with "Maximal allowed adjacent channels level difference" criteria operated incorrect
  • SPECTRUM mode functionality improved: displaying level of the maximal/minimal trace in the marker position added
  • Other non-critical bugs fixed


it088_build_130930.bsk2 from 30.09.2013
Operating system: v1.2.0.12
Application: v1.2.0.6

  • Added support of base module MB-08 hardware modification 2
  • Regional settings menu. Incorrect date format indication bug fixed (for the very first option): indicated - "MM.DD.YY", has to be - "MM/DD/YY"
  • Automatic display backlight switching off functionality improved. Backlight is always switched on, operating with external power on
  • Other non-critical bugs fixed

it088_build_131121.bsk2 from 21.11.2013
Operating system: v1.2.0.13
Application: v1.2.0.7

  • Channel plan selecting bug fixed: when you switch on the device, firmware failure message "HEAP_ALLOCATION_ERROR" appears on the screen in case the firmware failed to read selected channel plan's name from the file; further operating the device is impossible
  • LEVEL measurement mode bug fixed: measurement results may be unstable for channels with level close to 80 dBµV or 100 dBµV when operating in automatic attenuation mode due to the device's attenuator frequent switching
  • LEVEL measurement mode bug fixed: operating in "x4" or "x8" level averaging mode, measurement results are not always reset on selecting the channel with LEFT and RIGHT keys. In this case level value slowly goes from the previous channel level to the selected channel level
  • SPECTRUM measurement mode bug fixed: in some cases spectrum trace indicates incorrect after changing the spectrum span
  • Channel data logger bug fixed: digital channels carrier/noise ratio is not measured
  • Channel data logger bug fixed: device fails to work with pages, which do not have any related channel plan (such pages can be created using PC)
  • Channel data logger bug fixed: device fails to work with pages, which do not have any related limit plan (in case limit plan, used by the page, has been modified or deleted)
  • Channel data logger bug fixed: pages are incorrectly sorted in accordance with their status. Pages are supposed to be sorted in the following way: unmeasured pages, pages which do not match limit plan, pages which matches limit plan
  • Spectrum data logger bug fixed: in page measurement results viewing mode, changing the spectrum window central frequency in some cases leads to firmware failure message
  • PC operating mode bug fixed: on leaving the mode, removable module is not switched off. It leads to decreasing of the battery life
  • Limit plans manager bug fixed: digital channel carrier/noise ratio criterion is not included in the plan
  • Limit plans manager bug fixed: preVBER, postVBER and postRSBER criteria upper limit range value is incorrect -1*10-6. It is supposed to be -1*10-8
  • Limit plans manager bug fixed: limit plan parameter value entering with the keyboard is always performed in dBuV level units, despite the device's settings
  • MER/BER measurement mode functionality improved: channel measurement time counter added
  • MER indication improved: in case MER value is higher than 35 dB, it indicates with ">" sign
  • DVB-T channel measurement in PC operating mode bug fixed: for channels with low carrier/noise ratio value measurement results (MER, BER, constellation diagram) flashing back and forth in the ViewIt08C software
  • Other non-critical bugs fixed

it088_build_140901.bsk2 from 01.09.2014
Operating system: v1.2.0.16
Application: v1.2.0.8

  • MER/BER mode bug fixed: BER values indication exceed the bounds of the screen (e.g. "<1.0E-08")
  • Channel data logger functionality improved: on launching the measurement, MC module is warming up for 5 seconds, which improves level measurement accuracy (measurement results are 0.5...1.0 dB higher then real ones)
  • Spectrum data logger functionality improved: on launching the measurement, MC module is warming up for 5 seconds, which improves level measurement accuracy (measurement results are 0.5...1.0 dB higher then real ones)
  • PC operating mode bug fixed: in rare cases there may be loss of connection with the device
  • Other non-critical bugs fixed


it088_build_151008.bsk2 from 08.10.2015
Operating system: v1.2.0.18
Application: v1.2.0.8

  • Base Unit with hardware version 02.80.03 supporting added
