Capturing Intermittent Anomalies
One of the most difficult tasks that design engineers face is tracking down the cause of intermittent failures. If you know what
type of anomal
y y ou are looking for, then it is easy to configure the oscilloscope advanced triggering capability to isolate it.
However, when you do not know what you are looking for, it can be exceptionally tedious and time consuming, especially
given the low waveform capture rate on traditional digital storage oscilloscopes.
Digital Phosphor Oscilloscopes enabled by DPX technology have an exceptionally fast acquisition mode called FastAcq
that allows y
ou to find anomalies like these in a matter of seconds or minutes, where a regular DSO would take hours or
days to find the same event.
Use the following procedure to capture intermittent anomalies.
1. Probe the signal of interest. (Generally
this is one t
hat you think may be causing
problems.)
2. Push Autoset.
