Imporved calibration data organization in FLASH memory. No apparent effects in operation.


For T100plusR003a & T100plusR003 :

Calibration data in frequency "Unlock" and "Default" modes are stored in separated memory spaces .  A recalibration in the frequency "Unlock" mode is always needed whenever any of the frequency limits has been changed.  Otherwise, recalibrations are only needed when you want to change the reference plane, or to cater for changes in operating condititions like temperature.



Now when you switch between frequency "Unlock" and "Default" modes, T100+ will remember the "unlock" mode frequencies you have choosen.

The new "Reset to default" option in Settings Menu will bring your T100+ back to the default factory setting.  However, calibration data will not be altered.  Note: you will need to do a recalibration for the frequency "Unlock" mode after a "Reset to default" if any of the frequency limits has been changed (i.e. restored to their default factory settings).

Bug fixed: Backlight OFF now remains OFF after power off-on cycle. 


T100plusR003: Improved Smith Chart response to up/down keys, improved out of range (PLL unlocked) detection algorithm during setting of Frequency Unlock limits.
