Last time, Dave Jones tore down a low-end Agilent digital ‘scope on his EEVBlog.com site. This time, Tektronix loaned him a brand-new, $28,400 MDO4000 Mixed Domain Oscilloscope. What did he do? He reviewed it in an hour-and-a-half video (not shown here). Then he tore it apart in a separate 22-minute video (see below). When Dave tears something apart, you’re bound to learn one or two new things about system realization. This time’s no exception.
