A standout feature of the DOS1102 is its deep memory. According to the manual:
This report serves as a condensed manual and operational guide for the Hantek DSO1102B Digital Storage Oscilloscope. The DSO1102B is an entry-to-mid-level oscilloscope widely used in educational environments, repair workshops, and by electronics hobbyists. It is designed to visualize and analyze electronic signals, offering a bandwidth of 100MHz and a real-time sample rate of up to 1GSa/s.
Since the manual is not always included in printed form, follow these steps:
⚠️ Note: The DOS1102 is also sold under other brand names (e.g., Hantek, Zeeweii). However, the Hanmatek-specific manual matches the button layout and firmware version most closely.
Likely cause: Noise on the signal confusing the trigger. Manual reference: Trigger Coupling and Noise Rejection. Fix: In the Trigger Menu, change Coupling to HF Reject (high-frequency reject). This filters out sharp noise spikes. Alternatively, increase the Trigger Holdoff time—this tells the scope to ignore triggers for a short period after each trigger event.
Hanmatek DOS1102 is a popular entry-level digital storage oscilloscope known for balancing affordability with a robust feature set. This guide serves as a comprehensive overview and practical manual to help you master its interface, key specifications, and essential functions. Core Specifications
Before diving into the controls, it is important to understand what this hardware can handle: Bandwidth:
110MHz (suitable for most hobbyist and professional repair work). 2 Analog Channels. Sample Rate: 1 GSa/s (Giga-samples per second). 7-inch high-resolution color TFT LCD. Memory Depth: 10K points per channel. 1. Getting Started: The Interface
The DOS1102 layout is designed for logical flow, divided into three main control sections: Vertical System: Controls the Y-axis. Here you adjust the
to change the amplitude of the waveform on the screen and the knob to move the signal up or down. Horizontal System: Controls the X-axis (time). Use the
knob to expand or compress the waveform horizontally and the Horizontal Position knob to pan through a captured signal. Trigger System:
This is the most critical part for stabilizing your signal. The trigger determines exactly when the oscilloscope starts "drawing" the signal. 2. Initial Setup and Calibration
Before taking measurements, you must calibrate your probes to ensure accuracy. Connect the Probe: Attach your probe to Channel 1 (CH1). Attach to Probe Comp:
Connect the probe tip to the 5V/1KHz "Probe Comp" terminal on the front panel and the ground clip to the ground terminal. hanmatek dos1102 manual
button. The scope will automatically adjust settings to show a clear square wave. Compensate the Probe:
If the square wave looks distorted (rounded corners or "overshoot" spikes), use the adjustment tool (included with the probe) to turn the trimmer capacitor on the probe connector until the wave is perfectly flat and square. 3. Key Functions for Daily Use Automatic Measurements:
button to access a menu of 30+ automatic measurements, including Frequency, Peak-to-Peak Voltage ( cap V sub p p end-sub ), RMS, and Duty Cycle. Cursor Measurements: For manual precision, press
. You can move two vertical or horizontal lines to measure the exact difference in time or voltage between two points on the waveform. Storage and Export:
The DOS1102 features a USB port on the front. You can save screenshots (BMP) or waveform data (CSV) directly to a flash drive for reports or further analysis on a PC. Math Functions:
button allows you to perform operations between Channel 1 and Channel 2, such as addition, subtraction, multiplication, and FFT (Fast Fourier Transform) for frequency analysis. 4. Safety and Best Practices Grounding:
Always ensure the ground clip of your probe is connected to a proper ground point in your circuit.
connect the ground clip to a high-voltage point, as this can short-circuit the oscilloscope and your device under test. Voltage Limits:
Check the attenuation switch on your probe (1X or 10X). For most digital work, 10X is preferred as it increases the input impedance and protects the scope from higher voltages. Periodically check the Hanmatek Official Support
(or authorized distributors) for firmware updates to improve system stability or add features. function or help setting up the PC software for remote viewing?
