Default Ripple Measurement

Hi folks. I've gathered all the equipment for the power supply for a short time. My first victim HX750i. I did all test and last test ripple measurement. But I think it's a problem with measurements. Especially 12V channel.

OSC Rigol 1054z(Hacked 100 MHZ) I build own DC Load and Text Fixture. I followed intel atx spec.
