Hanmatek DOS1104 110MHz 4-Channel Digital Oscilloscope: The Ultimate Multi-Signal Analysis Guide (December 2025 Update)
In today's increasingly complex electronic designs — from multi-rail power supplies and embedded systems with numerous control lines to digital communication buses and mixed-signal circuits — four channels are often no longer a luxury, but a necessity. The Hanmatek DOS1104 delivers exactly that: a capable 110 MHz bandwidth with four independent channels in a compact, affordable benchtop package.
Priced around $185–$200 (frequently discounted from ~$200, with occasional holiday bundles), this 4-channel model has become a go-to upgrade for hobbyists, students, embedded developers, educators, and entry-level engineers who need simultaneous visibility of multiple signals without jumping to $400+ premium scopes.
Key Specifications at a Glance
| Feature | Specification | Why It Matters |
|---|---|---|
| Bandwidth | 110 MHz | Reliable capture up to ~80–100 MHz for most real-world signals |
| Channels | 4 simultaneous analog inputs | Monitor power, clock, data, control lines all at once |
| Real-time Sampling Rate | 1 GSa/s (interleaved/global); 250 MSa/s per channel | Clean waveform reconstruction across all 4 channels |
| Memory Depth | 10K–12K points per channel | Zoom deep into details without losing context |
| Display | 7-inch color TFT LCD (800×480, 65K+ colors) | Clear, bright view of multiple waveforms side-by-side |
| Vertical Sensitivity | 5 mV/div – 5 V/div | Handles low-level analog to higher-voltage signals |
| Trigger Types | Edge, Video, Pulse + advanced modes | Stable capture of complex multi-signal events |
| Extras | 30+ auto measurements, FFT analysis, Math functions, USB host/device, SCPI/LabVIEW support, waveform storage | Frequency domain, quick stats, automation & documentation |
Why the Hanmatek DOS1104 Excels in 2025
- True 4-Channel Power on a Budget Simultaneously view and compare four signals — perfect for analyzing SPI/I2C/UART buses (clock + data + CS), power supply ripple with multiple rails, MCU pin interactions, or amplifier input/output/feedback loops.
- Excellent Price-to-Performance For under $200, you get 4 channels at 110 MHz with 1 GSa/s sampling — specs that rival much more expensive models from a few years ago. Users praise its value as a step up from 2-channel scopes.
- User-Friendly for Real Work Auto-setup, intuitive knob/menu system, one-touch measurements, and a large sharp screen make multi-channel debugging fast and frustration-free.
- Practical & Portable Design Compact, lightweight build, USB storage for screenshots/waveforms, and SCPI compatibility for scripting/PC control. Powered by USB (5V) for flexibility.

Who Should Buy the Hanmatek DOS1104?
| User Type | Recommendation | Main Reasons |
|---|---|---|
| Embedded developers (MCU/FPGA projects) | ★★★★★ | Monitor clock, data, control, power simultaneously |
| Power electronics & SMPS designers | ★★★★★ | View multiple rails + ripple + switching signals |
| Students & electronics educators | ★★★★☆ | Ideal for teaching complex multi-signal systems |
| Audio/analog circuit builders | ★★★★ | Compare input/output/feedback across channels |
| Hobbyists upgrading from 2-channel | ★★★★ | Affordable way to gain true 4-channel capability |
| Pros needing >110 MHz or advanced decoding | ★★ | Consider Siglent/Rigol for deeper features |
Step-by-Step: Is the DOS1104 Right for You?
- Do you need more than 2 channels? Yes → DOS1104 is the sweet spot. No → Stick with cheaper 2-channel models like DOS1102.
- Highest frequency? Up to ~80–90 MHz real-world → Perfect. Above that regularly → Look at 200 MHz options.
- Budget range? $180–$250 → DOS1104 delivers unbeatable 4-channel value. $400+ → Consider models with deeper memory, better UI, or protocol decoding.
- Future needs? If protocol decoding or higher bandwidth is coming soon → Save for an upgrade. For most multi-signal tasks today, the DOS1104 will serve reliably for years.
Final Verdict (Christmas 2025)
The Hanmatek DOS1104 is one of the best sub-$200 4-channel oscilloscopes available — offering professional multi-signal visibility, solid accuracy, and modern features in a compact, easy-to-use package. It's the ideal choice for anyone tired of channel limitations and needing better system-level insight without premium pricing.
