Hanmatek Oscilloscope Comparison: DOS1102 vs DOS1102S vs DOS1104 – Which One Should You Buy in 2026?

If you're searching for Hanmatek oscilloscope comparison or wondering "which Hanmatek oscilloscope to buy", you're in the right place. Hanmatek's popular 110 MHz series offers excellent value for hobbyists, students, engineers, and technicians needing reliable digital storage oscilloscopes (DSOs) without breaking the bank.

All three models —Hanmatek Oscilloscope DOS1102, DOS1102S, and DOS1104 — deliver 110 MHz bandwidth, 1 GSa/s real-time sampling rate, and a clear 7-inch TFT LCD screen (800×480 resolution). They share core features like auto-setup, cursor measurements, FFT analysis, math functions (+, -, ×, ÷), multiple trigger modes (Edge, Video, etc.), and USB connectivity for PC control and data transfer.

But the differences in channels, built-in waveform generator, and use cases make each suited for specific needs.

Best Benchtop Oscilloscopes in 2026 - Hanmatek

(Visual comparison of key oscilloscope features — benchtop models like these excel in lab precision and multi-channel work.)

Here's a breakdown of the main specs and differences:

• ChannelsDOS1102: 2 channelsDOS1102S: 2 channelsDOS1104: 4 channels (ideal for simultaneous monitoring of multiple signals)
• Built-in Arbitrary Waveform / Function Generator (AWG/AFG)DOS1102: NoDOS1102S: Yes (built-in function generator for outputting sine, square, triangle, ramp, pulse, and more — great for stimulus-response testing)DOS1104: No
• Memory DepthDOS1102 / DOS1102S: ~10K pointsDOS1104: ~20K points (better for capturing longer waveforms or finer details at slower time bases)
• Best ForDOS1102: Entry-level / budget-conscious users needing basic 2-channel waveform viewing and analysisDOS1102S: Users who want an all-in-one tool — oscilloscope + signal generator in one compact unitDOS1104: Advanced debugging of complex circuits (e.g., microcontrollers, power supplies, multi-phase systems) where 4 channels provide huge time savings
• Price Positioning (approximate, check current pricing)DOS1102: Most affordableDOS1102S: Mid-range (added generator value)DOS1104: Highest in the series due to extra channels

All models are compact benchtop designs (roughly 301 × 152 × 70 mm, ~1.1–1.5 kg), run on standard AC power (with USB adapter compatibility noted in reviews), and include probes, power cord, and USB cable.
