Hanmatek Benchtop Oscilloscope Series Overview: DOS1102, DOS1102S, and DOS1104

Hanmatek has established itself as a go-to brand for affordable, high-performance test and measurement equipment. With a focus on delivering professional-grade features without the premium price tag, Hanmatek benchtop oscilloscopes are popular among electronics engineers, educators, lab technicians, hobbyists, and makerspaces. These digital storage oscilloscopes (DSOs) combine reliable signal capture, intuitive interfaces, and practical extras in compact, durable designs—making them ideal for R&D, debugging, education, and production testing.

In this overview, we'll explore the brand's strengths and provide a clear breakdown of the flagship 110 MHz models: DOS1102, DOS1102S, and DOS1104. All share core advantages like high sampling rates, large clear displays, and versatile triggering, but differ in channel count and added functions to suit various needs.

Why Choose Hanmatek Benchtop Oscilloscopes?

Hanmatek benchtop oscilloscopes stand out for their excellent value:

• Professional performance on a budget — 110 MHz bandwidth with fast sampling (up to 1 GSa/s in many configurations) captures details accurately for digital, analog, and mixed-signal work.
• User-friendly design — Large 7-inch TFT color LCD screens, intuitive menus, one-key auto-setup, and multi-language support make them accessible for beginners and efficient for pros.
• Built for real-world use — Low power consumption, quiet fanless or low-noise operation, USB connectivity for PC analysis, and included probes/accessories.
• Versatility — From basic waveform viewing to advanced features like FFT spectrum analysis, math functions, and (in select models) built-in waveform generation.

Whether you're analyzing SPI/I²C buses, debugging power supplies, teaching electronics, or characterizing circuits, these scopes deliver reliable results without unnecessary complexity.

Model Comparison: DOS1102 vs DOS1102S vs DOS1104

Here's a quick side-by-side look at the key models in the 110 MHz lineup:

• DOS1102 — The entry-level workhorse 2 channels, 110 MHz bandwidth, high sampling rate (often listed up to 1 GSa/s), 7-inch TFT display, deep memory, automatic measurements, FFT, and USB data export. Perfect for general-purpose use, hobby projects, and single/dual-signal debugging.

All models feature robust triggering (edge, pulse, video, etc.), cursor measurements, waveform storage, and PC software compatibility for deeper analysis.

Which Hanmatek Benchtop Oscilloscope Is Right for You?

• Choose DOS1102 if you're starting out, need a reliable 2-channel scope for everyday tasks, or want the best price-to-performance ratio.
• Choose DOS1102S if your work involves signal generation (e.g., testing filters, characterizing sensors, or lab experiments)—the integrated AWG saves space and cost.
• Choose DOS1104 if you frequently analyze multiple signals at once—4 channels unlock insights impossible with 2-channel models.

Hanmatek's benchtop series continues to evolve, with ongoing firmware updates and strong community support making these tools even more capable over time.
