Performance and Functionality
Bandwidth & Channels
The DS1102Z-E gives you 100 MHz bandwidth, but only 2 channels.
The DS1054Z gives you 4 channels, but only 50 MHz (unless unlocked).
If you need more channels, the DS1054Z wins.
If you need more bandwidth, the DS1102Z-E wins.
Signal Quality
The DS1102Z-E has noticeably:
- Cleaner signals
- Lower jitter
- Lower noise floor
Analog performance is simply better.
Memory Depth
Memory depth affects your ability to zoom and analyze long captures.
- DS1054Z: 12 Mpts
- DS1102Z-E: Up to 24 Mpts (upgrade)
For embedded work or serial decoding, deeper memory is extremely useful.
Waveform Update Rate
Both scopes peak at around 30k wfms/s, but the DS1102Z-E tends to maintain higher speeds during complex captures.
Serial Protocol Decoding
Both scopes require optional upgrades for decoding.
The DS1102Z-E provides:
- Smoother decoding
- Less lag when navigating long captures
- Better zoom performance
Usability and Interface
Both scopes share:
- Rigol’s familiar UI
- Similar button layout
- Identical learning curve
The DS1102Z-E benefits from:
- Faster menu response
- Improved rendering of math waveforms
- Better trigger performance
These improvements matter for frequent or professional users.
Build Quality and Design
DS1054Z
- Proven, durable design
