The next menu is displayed after the answer.
When a selection is made, the menu will disappear from the display and
the control will be on the tuning window.
The right top hand corner of the tuning window shows which tuning is
activated. The user can tune the current value with the plus <+> and
minus <–> keys.
Tune TX I DC Offset
The DC Offset is shown as a percentage of the maximum value. 0 %
means that there is no DC. The value range is –100 %...100 %. The value
is rounded to the nearest integer value.
Tune TX Q DC Offset
The operation of this function is the same as the previous one, except with
this selection, the Q branch DC Offset is tuned.
Tune TX I and Q DC Offset
The operation of this function is the same as the previous one, except with
this selection, both I and Q branch DC Offset is tuned. When plus <+> or
minus <–> key is pressed, both values are changed to the same direction.
If another value is in the limit value it does not change, but the other value
will change.
