From the developer:
The initial release of the QSB Scope application configures a QSB-M device to stream analog input every 1.95ms and digital input when the input value changes (also limited to every 1.95ms). The resulting input is then displayed to look much like a basic oscilloscope.
The QSB Scope is capable of displaying 1 channel of analog and 4 channels of digital input.
