Heavyweight emulator is a period-4 oscillator found by Robert Wainwright in June 1980. It is the largest of the three standard emulators and produces sparks similar to those of the heavyweight spaceship.

"Heavyweight emulator" most often refers to the "cis" variant displayed to the right; there is also a less-used "trans" variant of this oscillator.
