Yes, if your probes have the ground clips, you need to put those onto ground test loops. I don't know about Star Wars, but there are a few ground test loops around the vector output section of Tempest boards.

Otherwise, most Tek scopes have a banana plug where you can plug in a ground, you can connect that to any ground on the PCB.

Without ground, you will get an image, but it will be distorted and move around instead of steady.
