Resolution BW and Scan Points

When the programme starts, it is set to manual Resolution Bandwidth (RBW) and automatic calculation of Points.
The number of scan points is calculated using the formula:

Points = (Frequency Span in kHz) / (RBW in kHz / 2)

It's not possible to have auto scan points and auto RBW because the RBW is not known - it can't be retrieved from the TinySA. Once RBW is set to 'auto' using the drop-down box, the Scan Points should be set manually.

Both RBW and Scan Points can be set manually.
