it081_build_120813.bsk2 from 13.08.2012
Operating system: v1.2.0.9
Application: v1.2.0.7
-----------------------------------

- LEVEL, SCAN and SPECTRUM modes functionality improved: automatical attenuation detecting algorithm improved;
- SPECTRUM mode functionality improved: quick measurement mode added;
- Frequency saving bug fixed: in some cases after switching off and consecutive switching on the device, frequency was set equel to the frequency of the first channel of the channel template; 
- SPECTRUM mode bug fixed: in some cases attenuator was set incorrect in manual attenuation mode;
- PC operation bug fixed: in some cases automatical attenuation detecting algorithm operated incorrect;
- Battery charge level indication algorithm improved;
- Graphical system bug fixed: in some cases, operating in one of the measurement modes, user could see artefacts on the device screen;
- Other non-critical graphical user interface bugs fixed.

it081_build_130103.bsk2 from 03.01.2013
Operating system: v1.2.0.10
Application: v1.2.0.8
-----------------------------------

- 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;
- SCAN mode bug fixed: in some cases level of the first channel measured inaccurate;
- 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.

it081_build_131121.bsk2 from 21.11.2013
Operating system: v1.2.0.13
Application: v1.2.0.9
-----------------------------------

- 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 dBuV or 100 dBuV 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: 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: limit plan parameter value entering with the keyboard is always performed in dBuV level units, despite the device's settings;
- Return path test and measurement set operating modes bug fixed: In "Fr.resp", "MiniScan" and "Ingress" modes level is always shown in dBuV units, despite the device's settings;
- Other non-critical bugs fixed.

it081_build_151008.bsk2 from 08.10.2015
Operating system: v1.2.0.18
Application: v1.2.0.9
-----------------------------------
