How to Use Hantek DOS1104 Portable 4-Channel Oscilloscope (110MHz)
1️⃣ What is a 4-Channel Portable Oscilloscope?
The Hantek DOS1104 is a portable digital oscilloscope with four independent input channels, designed to capture and analyze multiple electrical signals simultaneously. Key features include:
4 signal channels – observe multiple signals in real time.
110MHz bandwidth – suitable for medium- to high-frequency signal analysis.
Portable design – compact and easy to transport for field diagnostics.
Advanced triggering and analysis tools – stabilize complex signals and perform automatic measurements.
Purpose: The DOS1104 is widely used in electronics development, industrial maintenance, power system testing, and education, where engineers need to compare and analyze several signals at once.
2️⃣ How it Works
The oscilloscope measures voltage as a function of time and displays the waveform visually:
Signal input: Probes connect the oscilloscope channels to the test points.
Signal conditioning: The input stage applies attenuation, amplification, and coupling (AC/DC).
Analog-to-digital conversion: Signals are sampled at high speed and converted into digital data.
Waveform display: The processor renders waveforms on the screen with time and voltage scales.
Trigger system: Stabilizes periodic signals so they appear steady.
Analysis tools: Automatic measurements, cursors, and waveform math help interpret signal behavior.
Tip: Multi-channel observation allows you to compare signal timing relationships, such as input vs. output or phase differences.

Why it matters:
Four channels enable multi-signal comparison and system-level diagnostics.
High sampling rate ensures waveform accuracy and detailed transient capture.
Advanced triggering allows stable display of complex or intermittent signals.
Power electronics testing – monitor control signals, switching waveforms, and load response.
Motor drive and inverter diagnostics – compare multiple phase signals.
Embedded system development – verify timing between digital control lines.
Field service and maintenance – portable design enables on-site measurements.
Example scenario:
An engineer troubleshooting a switching power converter monitors gate drive, input voltage, output voltage, and feedback signal on four channels simultaneously. This reveals a timing delay causing instability.
5️⃣ How to Use the Device (Step-by-Step)
Safety Preparation
Ensure probes are properly rated.
Use appropriate personal protective equipment.

Adjust Horizontal Scale (Time)
Set time/div to view one or more waveform cycles.
Configure Trigger
Select trigger source channel.

Measure Signals
Enable automatic measurements.
Use cursors for manual analysis.
Apply math functions (CH1–CH2, etc.).
Capture and Store Data
Freeze waveform using single capture.
Save waveform or screenshot to internal memory or USB.
Compare Multiple Signals
Use different colors and scales for each channel.
Align signals in time for phase analysis.
Pro tip: Use one channel as a trigger reference and others for comparison to maintain stable multi-signal display.

I purchased this for a small one time only learning activity I was doing for others. This was easy to setup because of the lack of options. This is as simple as it gets. I have used much better ones in labs, but for the cost this performed its intended function well.

very capable. great value.
Long time user of high end Tek, Philips etc. I find this scope very capable and more than I need for my hobby. I still have my Tektronics scope. If my office gets cold I will turn it on.
I thinkthe scope is a great bargain and is far superior to analogue Oscilloscopes
I thinkthe scope is a great bargain and is far superior to analogue Oscilloscopes I have owned 20 years ago and even one from 10 years back.
The one thing I wish it came with was more specific users manual. I think most people are moving up from simpler analogue scopes due to the price point and are not used to have the features available on such a complex device.
