## Usage tips
|
|
|
|
You can zoom the waterfall display by the mouse wheel. You can also drag the waterfall to pan across it.
|
|
|
|
The filter envelope can be dragged at its ends and moved around to set the passband.
|
|
|
|
However, if you hold down the shift key, you can drag the center line (BFO) or the whole passband (PBS).
