Fix generator output spikes
...
- Add manual overwrite in FPGA for hardware that is usually handled by sweep control
- Use static hardware configuration for generator (no sweep active anymore)

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
