OWON handheld oscilloscopes come in a range of models, each offering different bandwidths, sample rates, and memory depths. Typical specifications include 20 MHz to 100 MHz bandwidth, sample rates of 250 MSa/s to 1 GSa/s, and memory depth sufficient for capturing detailed waveforms. These devices often feature automatic measurement functions such as frequency, peak-to-peak voltage, and duty cycle, which simplify analysis. Advanced models may include waveform math functions like addition, subtraction, and FFT (Fast Fourier Transform) for frequency domain analysis, expanding the oscilloscope’s capabilities beyond basic signal visualization.
Triggering and Measurement Modes
- Edge Trigger Captures waveforms when a voltage crosses a specified threshold.
- Pulse Width Trigger Isolates pulses of specific duration for precise analysis.
- Video Trigger Synchronizes with video signals for detailed signal inspection.
- Auto Measurement Calculates frequency, amplitude, rise/fall times, and more.
Advantages Over Traditional Bench-Top Oscilloscopes
While bench-top oscilloscopes provide high-end capabilities, OWON handheld oscilloscopes offer several distinct advantages. Portability allows for easy use in fieldwork and tight spaces, while battery operation enables testing in locations without power outlets. The intuitive interface and built-in measurement tools reduce the need for additional instruments or complex setups. Additionally, handheld oscilloscopes often feature protective rubber housings to withstand accidental drops, dust, and vibrations, making them well-suited for industrial and outdoor environments. Despite being compact, they retain a level of precision and versatility comparable to traditional bench-top models, bridging the gap between mobility and professional functionality.
