Hanmatek DOS1102S 110MHz 2-Channel Oscilloscope & Waveform Generator
In 2025, the Hanmatek DOS1102S meets the growing demand for integrated electronics test solutions that save space, time, and money. This powerful 2-in-1 benchtop instrument combines a true 110 MHz digital storage oscilloscope Hanmatek DOS1102S with a built-in DDS waveform generator (AWG). Priced around $159–$180 (often on sale from ~$200), the Hanmatek DOS1102S has become a favorite among hobbyists, students, educators, repair technicians, and entry-level engineers who need both signal observation and stimulus generation without buying two separate instruments.
This complete guide explains why the DOS1102S is one of the smartest value picks in the sub-$200 category and helps you decide if it's the right all-in-one scope for your workbench.
Quick Specs at a Glance (2025 Model)
| Feature | Specification | Why It Matters |
|---|---|---|
| Bandwidth | 110 MHz | Accurately captures signals up to ~80–100 MHz |
| Channels | 2 simultaneous analog inputs | Compare signals, input vs output, clock & data |
| Real-time Sampling Rate | 1 GSa/s (single ch) / 500 MSa/s per channel (dual) | Clean capture of fast edges without aliasing |
| Memory Depth | ≥10 kpts per channel | Zoom deep into waveforms for detailed analysis |
| Display | 7-inch color TFT LCD (800×480, 65K colors) | Bright, sharp, readable even in bright labs |
| Built-in Waveform Generator | DDS/AWG: Sine, Square, Ramp, Pulse + 16 Arbitrary | Up to 10 MHz output — perfect for stimulus testing |
| Vertical Sensitivity | 2 mV/div – 5 V/div | Handles low-level analog & digital signals |
| Trigger Types | Edge, Pulse, Video, Slope + more | Reliable capture of complex or intermittent events |
| Extras | FFT (voltage-based), 30+ auto measurements, USB host/device, SCPI support, waveform save/recall | Frequency analysis, documentation, PC integration |
Why the DOS1102S Stands Out in 2025
- True 2-in-1 Convenience No more swapping cables between scope and separate function generator. Generate test signals (sine up to 10 MHz, square, ramp, pulse, arbitrary) and immediately view the response on the same screen — ideal for filter testing, amplifier characterization, MCU stimulus, sensor simulation, and more.
- Unbeatable Value For under $180, you get performance that rivals entry-level scopes from big brands costing 2–3× more a few years ago. The integrated AWG alone saves you $80–$150 compared to buying a standalone generator.
- User-Friendly for Beginners & Pros Auto-setup, intuitive knob/menu system, one-click 30-parameter measurements, and zoom/FFT functions make it accessible for students while powerful enough for real debugging.
- Solid Build & Practical Extras Sturdy enclosure, responsive controls, bright display, USB storage for screenshots/waveforms, and SCPI compatibility for automation/scripting.

Who Should Buy the Hanmatek DOS1102S?
| User Type | Recommendation | Main Reasons |
|---|---|---|
| Students & Electronics Educators | ★★★★★ | All-in-one for teaching signal gen + analysis |
| Arduino/ESP32/STM32 Hobbyists & Makers | ★★★★★ | Generate test signals for sensor/MCU debugging |
| Analog/Audio/Power Supply Repair Techs | ★★★★☆ | Stimulus + measurement in one compact unit |
| Entry-Level R&D / Embedded Developers | ★★★★ | Saves bench space & cost for filter/amplifier tests |
| Professionals needing >100 MHz or 4ch | ★★ | Step up to higher-end models (Siglent/Rigol) |
Step-by-Step: Is the DOS1102S Right for You?
- Do you need signal generation? Yes → DOS1102S is a no-brainer. No → Consider the cheaper DOS1102 (same scope, no AWG).
- Highest frequency you work with? Up to ~80–90 MHz real-world → Perfect fit. Above 100 MHz regularly → Look at 200 MHz models.
- Budget range? $150–$200 → DOS1102S offers unbeatable 2-in-1 value. $300+ → Consider Siglent SDS1104X-E or Rigol for better UI/firmware.
- Future needs? Plan protocol decoding, 4 channels, or higher BW → Save for an upgrade. For most everyday tasks, the DOS1102S will serve reliably for years.
Final Verdict (Christmas 2025)
The Hanmatek DOS1102S remains one of the strongest 2-in-1 oscilloscope + waveform generator options available today. It delivers professional-grade signal analysis and stimulus capability in a compact, affordable package — making it an ideal upgrade for anyone tired of juggling separate instruments.
If your work involves both observing and generating signals below ~100 MHz, and you want maximum functionality without breaking the bank, the DOS1102S is hard to beat.
