Dave started out wanting to investigate the poweron spike on the Rigol DP832 Lab Power Supply, but ended up hunting down a reset bug that uncovered a bad thermal design mistake in the supply.
Watch Dave hunt it down step by step, and almost get duped by some marginal oscilloscope triggering.
How will Rigol respond to this?
UPDATE: Rigol have already fixed this issue: http://www.eevblog.com/forum/blog/eev...
