Redstone™ OSA305
Chapter 3: Using the OSA
When the "Free-space Alignment" window is closed, and whenever necessary
during normal operation such as when the input source conditions have changed
considerably, the autogain algorithm will run a series of short sweeps to determine
optimal gain and offset settings. An overlay window will appear during this time
advising the user to wait for optimization to complete.
