3.7 ON Key
Use these key to control the main output signal. When the output is active, an internal LED will illuminate the button.
3.8 Cursor Movement Keys
Use these keys to move the cursor (when visible) either left or right. They are used in conjunction with the rotary input

When the waveform generator finishes the diagnostic self-test routine, it enters the local state (LOGS) and assumes
