The signal generator is very simple. A resistive (2R-R) network driven by the FPGA and an opamp driver. Output is limited to 3V3. Any signal amplitude change is done in "software" and reduces the resolution on the output. Not even sure if it is possible to adjust. Never used it. |

Where can I add volume? so that we can adjust the amplitude |

Could you please draw a circuit diagram for me? |

Search the internet. There are plenty examples to be found. Something like this for instance: https://www.eleccircuit.com/the-signal-amplifiers-can-set-input-and-output-ratio/ |
