Summary of Rigol DS1000Z & DS2000 Oscilloscope Jitter Problems
Dave investigates two critical jitter issues affecting Rigol DS1000Z series oscilloscopes, specifically the DS1104Z and DS1054Z models. The first issue involves a modulated sampling or trigger jitter occurring at 5 microsecond intervals. The second problem is severe jitter found in AC coupled trigger mode, which also impacts the DS2000 series scopes.
Parts used in the Rigol DS1000Z Oscilloscope Investigation:
- Rigol DS1104Z oscilloscope
- Rigol DS1054Z oscilloscope
- Rigol DS2000 series oscilloscope
Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z
Some sort of modulated sampling/trigger jitter problem at 5 microsecond intervals (the “5us jitter problem”). And severe jitter with the AC coupled trigger mode, a problem which is also present on the DS2000 series scopes as well.
