Dave walks around Cebit Australia 2014 at Homebush Bay in Sydney. Show highlights footage here: http://www.youtube.com/watch?v=RwAhluh7MUE If you don't like shaky hand held walking footage, motion blur, or camera image stabilisation, don't watch it, no complaints. I do not have a steadycam, and I don't want advice on a steadycam, and I don't care how much you can't watch it. Thanks.

Dave tries out the new DS1054Z firmware from Rigol that is supposed to fix the 5us delay jitter issue, and the AC Trigger Coupling jitter issues. Have they fixed it, or is there still a problem? What caused the 5us jitter issues to begin with, Dave also investigates the ADC PLL based sample clock with an e-Field probe and the Rigol DSA815 spectrum analyser. Did Rigol also change the PLL coefficients?
