How do you configure a sine wave generator to oscillate between 0 and +6 volts? |

You add a DC offset. On the FY6800 as example, photos available on eBay/Bandgood/AliExpress, you can see that this is one of the parameter: Type (sine wave), Frequency (FREQ), Amplitude (AMPL), Offset (OFFS) , Duty and Phase. You also have the possibility to add that offset in the simulator of Circuit Lab. If you check with an oscilloscope, be sure to NOT reject the DC component of the signal that you sample with the probe. |

What settings do I use for Offset and Amplitude to get a sine wave that oscillates between 0 and +6 volts? |

The amplitude of the sine wave can be given as peak to peak, in this case it would be 6 Vpp ( pp == peak to peak) or from DC to peak, in that case it would be 3 V. The DC offset will be of 3V in both cases. Many generators assume a "load" of 50 Ohm. You may get a different voltage as output if your load is not 50 Ohm for these generators. Also, these generators have a maximum output current, so you may have to buffer it (OpAmp or transistor) before presenting it to your circuit. |

What worked was Amplitude 3V with Offset of 3V. This generated a sine wave with peak at 6V and trough at 0V. |
