How to View a waveform of an inverter on a oscilloscope

Checking the waveform on a car plug-in inverter, like the type you would use to power a laptop computer in a car. I used my NLS MS-215 Miniscope to view the waveform. As you can see it is much more like a squarewave than a sinewave, like a staircase waveform.
