How to Use Hanmatek DOS1102 110MHz 2-Channel Oscilloscope
1️⃣ What is a 2-Channel Oscilloscope?
The Hanmatek DOS1102 is a digital 2-channel oscilloscope designed to capture, display, and analyze electrical signals in real time. Key features:
110MHz bandwidth – captures high-speed signals in analog and digital circuits.
Two input channels – allows simultaneous observation of two signals.
Digital display – high-resolution waveform visualization.
Advanced triggering and measurement tools – edge, pulse, and slope triggers; auto and manual measurements.
Purpose: Ideal for electronic design, repair, troubleshooting, and education, the DOS1102 helps engineers, technicians, and hobbyists analyze waveforms, voltage, frequency, and timing relationships in circuits.
2️⃣ How it Works
The DOS1102 functions as follows:
Signal Acquisition: Connect the probes to the circuit under test.
Analog Front-End: Signals are conditioned through attenuators, coupling (AC/DC), and vertical scaling.
Digital Conversion: Signals are sampled using an ADC (Analog-to-Digital Converter).
Display & Analysis: The processor displays the waveform on the screen with time vs. voltage axes.
Advanced Features:
Trigger system stabilizes repeating waveforms. Cursors and auto-measurements provide quantitative analysis (frequency, peak-to-peak voltage, RMS).
Tip: Always start with proper vertical and horizontal scaling to clearly observe waveform details.

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.

Good Scope and nice bandwidth
Great working scope and meets bandwidth specs. easy to use with short learning curve.

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.
We recently purchased the Hanmatek AHO814 4-Channel Smart Touchscreen Oscilloscope, 100MHz, directly from Hanmatek, and I have been very impressed with both the oscilloscope and the service I received. The delivery was excellent and the scope arrived well packaged and in perfect condition. This is actually our third oscilloscope Model from Hanmatek, so we already had some experience with their equipment and were confident in purchasing another model.
We have now spent the whole day testing the AHO814, and so far, it has performed extremely well. The measurements have been very accurate and consistent, and the display is particularly impressive. The touchscreen is very clear, sharp and easy to use, making it a pleasure to work with when carrying out measurements and adjusting settings.
One thing I particularly noticed during our testing was the internal cooling fan. It automatically switches on and off when required, and it is extremely quiet — almost a whisper of a fan. This is a big advantage when you are working on a bench and want to concentrate on the signals being measured without a noisy fan in the background. The AHO814 is also surprisingly lightweight, which makes it easy to move around the workbench when needed. Although it is a relatively compact and lightweight oscilloscope, it has a very impressive range of features, including many of the functions and measurement capabilities that we have on our higher-end **Rigol oscilloscope**. Having these features available on the Hanmatek makes it a very capable instrument for both everyday electronics work and more detailed testing. After spending a full day putting the AHO814 through its paces, I am very pleased with the results. The waveform display is clear, the touchscreen responds well, and the automatic measurements have been giving us very good and reliable results. Overall, we are very happy with the **Hanmatek AHO814**. Considering its features, build quality, excellent display, quiet cooling system and measurement performance, it has made a very good addition to our test equipment. This is now our third Hanmatek Model oscilloscope, and based on our experience so far, we have been very happy with the quality and performance of Hanmatek equipment.
This is the first Oscilloscope I've purchased for home use and so far I really like this scope. Small and light weight, but still has the large 7 inch screen and all the manual knobs and buttons you would use most frequently. Very easy to setup and use. Love that this unit has 110MHz of bandwidth and up to 1GSa/s, and the integrated waveform generator is really nice to have. Came well equipped with probes, BNC cables and power supply. Fantastic deal for $150.
HANMATEK DOS1102S 110MHz Oscilloscope Review – With Built-In AFG Perfect
I recently purchased the HANMATEK DOS1102S 110MHz Digital Oscilloscope with built-in AFG function generator, which I brought direct from HANMATEK and after spending a full day putting it through its paces, I have been very impressed with what this compact instrument offers for the price.
Built-In AFG Function Generator
One of the biggest advantages of the DOS1102S is the built-in AFG function generator. Having signal generation built directly into the oscilloscope is extremely useful for testing circuits and experimenting with different waveforms.
You can generate a test signal and immediately view it on the oscilloscope, making it a very convenient all-in-one test instrument. For beginners, it also means you don't necessarily need to purchase a separate function generator.
Trigger Functions
The trigger section is particularly impressive for an oscilloscope in this price range. Along with the usual trigger controls, the DOS1102S includes Trigger Holdoff, which can help stabilise more complicated or repetitive waveforms.
This gives you greater control over how the waveform is displayed and is a useful feature for more advanced testing.
Maths and FFT
The Maths and FFT functions are another useful addition. FFT allows you to examine the frequency content of a waveform and identify frequency components and harmonics.
While it isn't intended to replace a dedicated spectrum analyser, having FFT available on an affordable oscilloscope provides another useful tool for investigating signals.
Cursors and Measurements
The cursor functions are very useful for taking voltage and time measurements directly from a waveform. I particularly like the cursor lock function, which allows the two cursors to be moved together.
I have compared measurements from the DOS1102S against other test equipment across different waveforms and have been very pleased with the results.
The scope also provides automatic measurements such as frequency, period and peak-to-peak voltage, making it easier to quickly analyse a signal.
Horizontal Zoom and Acquire
The horizontal zoom function allows you to examine sections of a captured waveform in greater detail without completely changing the original time-base settings.
The Acquire menu also provides useful options such as averaging, which can help produce a cleaner and more stable waveform when dealing with noisy signals.
Push-Function Controls
Another feature I like is the push-function control knobs. Some controls can also be pressed to provide additional functions, such as quickly returning vertical, horizontal or trigger positions to their centre or zero point.
It is a small detail, but it makes the oscilloscope quicker and easier to use.
Five -Hour Test
I used the DOS1102S for approximately Five hours during a full day of testing, carrying out measurements, waveform testing and experiments using the built-in AFG.
Throughout the extended test, the oscilloscope performed well and I experienced no problems with its operation. I also compared DC voltage and cursor measurements against other test equipment and was very happy with the results.
Overall Verdict
Overall, I am very impressed with the HANMATEK DOS1102S 110MHz oscilloscope.
For the price, it offers an impressive range of features, including the built-in AFG function generator, Maths, FFT, Trigger Holdoff, cursor locking, horizontal zoom, automatic measurements and averaging.
It is easy enough for beginners to learn with, while still offering plenty of useful functions for experienced electronics users.
The built-in AFG is a particularly valuable addition, effectively giving you an oscilloscope and function generator in one compact instrument.
After using the DOS1102S extensively, I feel HANMATEK has produced a very capable and versatile oscilloscope that offers excellent value for money. I am very happy with mine and would have no hesitation recommending it to anyone looking for an affordable, feature-packed 110MHz oscilloscope.
