When you debug new designs, waveform and decode update rates can be critical – especially when you are attempting to find and debug infrequent or intermittent problems. These are the toughest kinds of problems to solve.
Faster waveform and decode update rates improve the probability of capturing elusive events. To understand why this is true, you must understand what is known as oscilloscope ‘dead time’. All oscilloscopes have ‘dead time’, the time between oscilloscope acquisitions when a scope processes the previously acquired waveform for display. During this period, the scope is essentially ‘blind’ to any signal activity that may be occurring.
