1.92 - The following behavior is implemented: analyzer saves (key "6") the measurement data the way it looks on the LCD screen. I.e. if calibration is applied the data will be saved with calibration applied. And AntScope software will display the same picture as analyzer itself when you load saved data into AntScope. If you are using AntScope to perform measurement the Analyzer will send data with calibration applied or not depending on whether the calibration is enabled on the instrument or not (which is selectable by F+2 key combination). Please be aware: it is impossible to view results without calibration applied in case the data was stored with calibration applied.
1.94 - bands selection screen added, some minor fixes
