3d97e4ca20 Minor GUI improvements 
- allow 'wrong' input for unit edits where only one case makes sense (e.g. 10mHz for 10MHz)
- fix behavior when changing center of span would exceed the allowed range
- only change value for level or points when editing is finished (not on every keyboard input)

c0e4f41115 Various small bugfixes 
- Improved device communication (callbacks for transmissions working properly now)
- Honor averaging when calibrating
- Ignore delayed points from last sweep during calibration
- Stop the sweep when disconnecting

fc3ce7a828 Improved spectrum analyzer mode 
- Faster sweeps by changing 2.LO only when necessary and using 400kHz I2C frequency
- Added FPGA settings for selectable ADC samplerate
- Additional measurement with different ADC samplerate when signal ID is on to remove ADC images
