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?
