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 anomaly you are looking for, 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 to find
infrequent anomalies, 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,
which allows you to find anomalies like these in a matter of seconds or minutes. A regular DSO would take hours or
days to find the same event.
Use the following procedure to capture intermittent anomalies.
1. Connect the probe to the input signal
source.
2. Push Autoset .
