Troubleshooting Circuits Using Parallel Buses
In this example, you are monitoring a parallel bus with your oscilloscope. You can use your MSO4000 Series oscilloscope with
its 16 digital channels to analyze the bus. The MSO4000 Series will not only let you see the o n-off status of the signals, b ut
will also decode the parallel bus signals for you.
Basic Strategy
First, you will d isplay and acquire the digital signals. T hen, you will search through the data with the search/ m ark functions.
NOTE. The MSO4000 Series oscilloscopes support triggering and decoding on Parallel bus signals.
