As a newbie, you should first read the Simulation Tutorial: [https://docs.easyeda.com/en/Simulation/Headings/index.html](https://docs.easyeda.com/en/Simulation/Headings/index.html) You cannot use the Signal Generator the way you are trying to. The Signal Generator and other EasyEDA simulated instruments are only for use in Time Domain simulations, i.e. simulations configured to run a Transient Analysis. You need to set up what's called an AC Analysis. This is explained in the Simulation Tutorial.
