Couple of points:
The screen shot shows a generator that has been freshly turned on. It defaults to the sine wave.
A power cycle resets the generator back to factory.
The reset button on the generator control panel resets the factory reset parameters in case you overwrite it messing with the generator's built in buttons.
Once Spooky2 has started and made contact with the generator, the waveform on the display will change from Sine to Arbitrary.
If it does not change on startup, Spooky2 did not see the generator.
Ensure you check the # of generators to find in the Settings tab if you have ruled out cables.
