4. Key Strengths of the Manual

• Visual clarity: Simple, labeled block diagrams of the front panel.
• Step-by-step: Menus are explained in numbered steps.
• Measurement examples: Shows how to measure a 1kHz square wave from the built-in probe compensation terminal.
• Compact size: Easy to keep near the bench.

Math Functions

The DOS1102 supports mathematical operations on waveforms: hanmatek dos1102 manual

• Addition (A+B): Useful for differential measurements.
• Subtraction (A-B): Essential for rejecting common-mode noise.
• FFT: Fast Fourier Transform allows you to view the frequency spectrum of a signal, useful for audio analysis or identifying noise sources.

Chapter 4: Trigger System – Your Most Powerful Tool

Most "my scope isn't working" complaints stem from trigger confusion. The manual explains: The Hanmatek DOS1102 is a 2-channel, 110MHz digital

• Trigger types: Edge (most common), Pulse (glitch capture), Video (TV signals), and Slope.
• Trigger modes: Auto (sweeps even without trigger), Normal (only sweeps when trigger condition is met), and Single (captures one event).
• Trigger coupling: AC, DC, HF Reject (removes high-frequency noise), and LF Reject (removes low-frequency drift).

B. Horizontal Controls

These knobs control the time domain of the waveform. Visual clarity: Simple, labeled block diagrams of the

• POSITION: Moves the waveform horizontally left or right. This is used to view different parts of the signal cycle.
• SCALE (TIME/DIV): Adjusts the horizontal time base (e.g., changing from 1ms per division to 1µs per division). This changes the zoom level regarding time.

4. Basic Operation Procedures

8. Recommendations for Hanmatek (for future revisions)

1. Add a real-world measurement example (e.g., PWM signal analysis, ringing on a switching supply).
2. Expand the troubleshooting section beyond 5 items.
3. Include a firmware update procedure (even if just “contact support”).
4. Provide downloadable PDF with searchable text – current scans are often image-based.
5. Add a one-page quick reference card for button shortcuts.
