Using Voltage Function Generators

I'm having trouble understanding how to use the Voltage Function Generator as my source. My target voltage is 120v, yet it comes up as -120v when using the voltage meter. I think I'm doing something wrong here and I'm not quite sure what it is. The values are as follows: DCOffset: 0 Phase: 90 degrees Amplitude: 120v Frequency: 60Hz

I've tried adding the circuit, but it won't work, so hopefully this is enough information.

The voltage meter / DC simulation only shows the result at time t=0. Since you've set phase to 90 degrees, this corresponds to the negative peak of the sine wave. If you're using a function generator, you almost certainly want to be using time-domain simulation mode.

Here's an example of how the function generator's Phase parameter works:
