Application Examples

10.

Analyze the decoded packets in the protocol
layer. Did you send the data bytes in the
correct order? Did you use the correct
address?

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 on-off status of the signals, but
will also decode the parallel bus signals for you.

Basic Strategy

First, you will display and acquire the digital signals. Then, you will search through the data with the search/mark functions.

NOTE.

The MSO4000 Series oscilloscopes support triggering and decoding on Parallel bus signals.
