@ -116,13 +116,13 @@ Done since the fork
- Enhanced channel analyzer: enhanced scope and spectrum displays as mentioned above, make the spectrum display synchronous to scope (hence triggerable a la E4406A).
- Sort channel plugins by delta frequency and type before saving to preset
- Implemented scope pre-trigger delay
- Implemented variable scope memory depth
- Implemented trigger delay
=====
To Do
=====
- Variable scope memory depth
- Trigger delay
- Enhance presets management (Edit, Move, Import/Export from/to human readable format like JSON)
- Level calibration
- Enhance WFM (stereo, RDS?)
