Before your first measurement, follow these essential setup steps to ensure accuracy and device safety. HANMATEK DOS1102 Digital Oscilloscope User Manual

You can access the official Hanmatek DOS1102 User Manual on the Manuals+ website, which includes details on setup, operation, and troubleshooting.

Since the Hanmatek DOS1102 is often identified as a rebrand of the Owon SDS1102, you can also refer to the Owon SDS1102 Manual for highly detailed technical documentation. Hanmatek DOS1102: Fast Setup Post

If you're just getting started, here’s a quick-reference guide to your new scope: 1. Hardware Overview Dual Channels: 110MHz bandwidth with a 1GS/s sample rate.

7-inch Display: Clear screen for real-time waveform monitoring.

Ultra-Thin Profile: Measures roughly 3 inches wide, making it perfect for crowded desks. 2. Key Functional Buttons Manufacturer's Website : You can try visiting the

Auto Set: The "magic button" that automatically adjusts the vertical and horizontal scales to display a stable signal.

Measure: Pulls up automated readings like RMS voltage, peak-to-peak, and frequency.

Acquire: Allows you to switch between Sampling, Peak Detect, and Averaging modes to filter out noise. 3. Using the Probes Your scope comes with two T-5100 probes.

10X Mode: Use this for high-frequency signals up to 100MHz. It increases input impedance and reduces circuit loading.

1X Mode: Best for low-voltage/low-frequency signals, but limited to a bandwidth of about 6MHz. 4. Calibration Check

Before your first measurement, hook your probe to the Probe Comp terminal on the front panel. You should see a clean 5V square wave. If the waveform looks distorted (rounded or peaked), use the adjustment tool on the probe until the wave is perfectly flat.

If you're having trouble with PC connectivity, keep in mind that these units typically use standard SCPI commands for serial communication, though you may need to ensure your software is configured for the correct carriage return/newline line endings.

Do you have the standard probes or are you using different ones?

• ESD handling instructions

7. Connectivity and Firmware

The DOS1102 typically includes a USB Device port (Type-B) on the back.

• PC Connection: You can connect the scope to a PC.
• Software: While some manuals reference proprietary software, many users utilize open-source alternatives like OpenHantek (compatibility varies by firmware version) for data logging and PC-based control.
• Firmware Updates: The manual advises checking the manufacturer's website for firmware updates that fix bugs or improve the UI responsiveness.

Problem 3: "My USB connection to the PC isn't working."

Likely cause: Missing driver or wrong connection order. Manual reference: Remote Control & PC Software Appendix. Fix: Install the drivers from the supplied CD before connecting the scope. Use a high-quality USB-B (printer) cable. On the scope, go to Utility > I/O Setting and ensure USB is enabled. On the PC, open the software (likely EasyScopeX or similar) and select the correct COM port.

Understanding the Manual’s Structure

The official manual (approx. 80-100 pages) is divided into these sections:

1. Safety and Preparation – Probe adjustment, power requirements, ground isolation warnings.
2. Front Panel Overview – Function of each button (CH1, CH2, Auto, Run/Stop, Measure, Utility).
3. Menu System – How the four soft keys change function depending on the active mode.
4. Vertical, Horizontal, and Trigger Controls – Setting voltage/div, time/div, trigger level, edge/slope.
5. Measurement Functions – 32 automatic measurements (voltage, time, delay, etc.).
6. Cursor Mode – Manual and track cursors for precise readouts.
7. Math Functions – Add, subtract, multiply, FFT.

Horizontal Time Base

1. Turn the Time/Div knob to expand (zoom in) or compress (zoom out) the waveform on the time axis.
2. The number at the bottom center of the screen indicates the time per division (e.g., 1ms, 500µs).

Chapter 4: Trigger System – Your Most Powerful Tool

Most "my scope isn't working" complaints stem from trigger confusion. The manual explains:

• 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).
