HO102S 3-in-1 Handheld Oscilloscope Review: In-Depth Testing and Real-World Experience
If you're searching for a HO102S review or exploring a reliable handheld oscilloscope multimeter combo, the Hanmatek HO102S stands out as a versatile, portable 3-in-1 tool that packs serious value. Combining a 100 MHz dual-channel oscilloscope, a high-count digital multimeter, and a 25 MHz waveform generator into one compact device, it's designed for engineers, technicians, hobbyists, and field service pros who need powerful diagnostics without lugging around heavy bench equipment.
In this detailed review, we'll dive into the key aspects—screen quality, channel performance, storage capabilities—and share actual measurement examples from real-world use. Whether you're troubleshooting automotive sensors, debugging circuits, or teaching electronics, the HO102S delivers impressive performance in a lightweight package.
Unboxing and First Impressions
Right out of the box, the HO102S feels solid and well-built. The package includes:
- The main unit
- Two oscilloscope probes
- Multimeter test leads
- Signal generator output cable
- USB Type-C cable and charger
- Carry case
- User manual
At just around 600-700g, it's truly portable—fits easily in a toolkit or backpack. The build quality is reassuring for field use, with a rugged feel and good button responsiveness.
Why Choose Hanmatek Handheld Oscilloscopes
Screen: Clear and Readable in Any Environment
The 3.5-inch TFT HD LCD screen (320x240 resolution, 65,535 colors) is one of the HO102S's strongest features. Waveforms appear sharp and vibrant, with excellent contrast even in bright outdoor light or dim workshops. The backlighting adjusts nicely, and the interface is intuitive—menus are logical, and one-key auto-setup quickly optimizes waveforms for quick analysis.
In practice, the display handles dual-channel views smoothly without clutter. Text and measurements are large enough for quick glances during fieldwork.
Dual Channels: Performance and Accuracy
With 100 MHz bandwidth and a real-time sampling rate of 250 MSa/s, the HO102S captures signals faithfully up to its rated frequency. The dual independent channels allow simultaneous viewing of two signals—perfect for comparing inputs/outputs, clock vs. data lines, or differential measurements.
Triggering is reliable (edge, pulse, video modes), and features like math functions (add/subtract/multiply) and FFT analysis add depth for frequency-domain work. Vertical resolution is solid, and the 8K memory depth provides decent capture length for zooming into transients.
Storage and Memory: Handy for On-the-Go Analysis
The built-in memory supports saving up to dozens of waveforms, setups, and screenshots—great for documenting issues or comparing before/after fixes. Files transfer easily via USB Type-C to a PC for further analysis or reporting. This is especially useful in field service where you need to log data without a laptop nearby.
Real-World Measurement Examples
Here are some practical tests that showcase the HO102S in action:
- PWM Signal Analysis (Automotive/Embedded) Capturing a 50% duty cycle PWM from a microcontroller at 10 kHz: The waveform displayed cleanly, with accurate rise/fall time measurements and frequency readout. Dual channels let me overlay the input trigger signal effortlessly.

- Sine Wave from Built-in Generator Using the 25 MHz waveform generator to output a 1 MHz sine wave and loop it back: Clean capture with minimal distortion. Note: At higher frequencies, expect some 50Ω impedance mismatch effects if directly connected—standard for most generators.
- Multimeter Mode – Voltage and Continuity Switching to multimeter mode (20,000 counts) for DC voltage checks on a battery circuit: Readings were stable and matched a Fluke reference within 0.1%. Continuity beep is responsive, and resistance/capacitance modes handled typical component checks well.
- Pulse Train with Glitches Testing a noisy digital line: The high sampling rate caught brief glitches that lower-end scopes might miss, aiding quick debugging.
