Summary of How To Reverse Engineer A Rigol DS1054Z
This article summarizes EEVblog #675, where Dave reverse engineers a Rigol DS1054Z oscilloscope to extract its schematic. Key technical topics include the discrete transistor analog front end, software bandwidth limiting mechanisms, and decoding SMD transistor codes. The content also compares this model to the older DS1052E and explores the utility of a multimeter's low voltage ohms function for in-circuit testing.
Parts used in the Rigol DS1054Z Reverse Engineering Project:
- Rigol DS1054Z oscilloscope
- Rigol DS1052E oscilloscope
- Multimeter with low voltage ohms function
Dave shows you how to reverse engineer a PCB to get the schematic. In this case the new Rigol DS1054Z oscilloscope.
How does the discrete transistor analog front end and the software bandwidth limiting work?
How do you decode SMD transistor codes?
How does it compare to the old Rigol DS1052E?
Dave also discusses the low voltage ohms function of a mulitmeter, how it’s useful, and how to test your multimeter to see if it will have any issues with in-circuit testing.
