A high-resolution 12-bit oscilloscope offering 350 MHz bandwidth and professional-grade features at a competitive price.
Overview
The Siglent SDS3034X HD is part of Siglent’s advanced Super Phosphor Oscilloscope series, designed for engineers who demand precision and clarity in waveform analysis. With 350 MHz bandwidth, 2 GSa/s sampling, and 12-bit vertical resolution, it delivers cleaner, more detailed traces than standard 8-bit scopes. Packed with decoding options, deep memory, and a sharp display, the SDS3034X HD competes strongly with more expensive models from Tektronix, Keysight, and LeCroy — but at a fraction of the cost.
Key Features & Specs
- Bandwidth: 350 MHz
- Channels: 4 analog inputs
- Sampling rate: 2 GSa/s
- Vertical resolution: 12-bit (vs. 8-bit in most entry/mid-tier scopes)
- Memory depth: Up to 200 Mpts (segmented acquisition supported)
- Waveform capture rate: up to 120,000 wfms/s
- Display: 10.1-inch TFT LCD, multi-touch support
- Built-in features: FFT, advanced math functions, protocol decoding (I²C, SPI, UART, CAN, LIN, etc.)
- Connectivity: USB, LAN, and option for web control

- Form factor: modern slim bench scope with responsive UI
Pros
- 12-bit resolution gives crisp, detailed waveforms for analog precision.
- Excellent value compared to Keysight/Tektronix equivalents.
- Wide protocol decoding support for embedded engineers.
- Large, sharp 10.1-inch touchscreen improves usability.
- Quiet operation and modern design for bench or lab.
Cons
- Higher cost than entry-level hobbyist scopes (e.g. Rigol DS1054Z).
- Menu-driven interface can feel slower than older “knob-heavy” designs.
- Some advanced features require optional licenses.
- Physically larger/heavier than compact budget scopes.
Who It’s For
- Professional engineers needing high-resolution measurements.
- Advanced hobbyists ready to move beyond entry-level 8-bit scopes.
- Embedded developers working with digital protocols.
- Labs and universities needing a reliable mid-range oscilloscope.
Verdict
The Siglent SDS3034X HD is an impressive balance between professional-grade performance and affordability. Its 12-bit resolution sets it apart from most competitors in this price range, offering visibly cleaner traces and more confidence in analog signal analysis. While not the cheapest option, it’s an investment-level tool that can serve engineers, technicians, and advanced hobbyists for years to come. If you want near-premium performance without the premium-brand price tag, the SDS3034X HD is one of the best choices in today’s market.
