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.

This makes taking measurements quicker and easier, particularly when comparing different points on a waveform. I have compared the DOS1102's cursor measurements against my other test equipment across a variety of waveforms, and the results have been very good. Horizontal Zoom The horizontal zoom function is another useful feature. It allows you to examine sections of a captured waveform in greater detail without having to completely change the original time-base settings. I have found this works well when looking closely at waveform details and makes examining captured signals much easier. Push-Function Control Knobs Another feature I really like is the way the control knobs operate. Several of the adjustment knobs can also be pressed, providing additional functions. For example, pressing the appropriate control can quickly return the waveform to a central or zero position. This applies to functions such as vertical position, horizontal position and trigger controls. It is a small detail, but it makes operating the oscilloscope quicker and more convenient. Voltage and Measurement Testing I have carried out DC voltage comparisons between the DOS1102 and a mid-range Rigol oscilloscope. I have also compared cursor measurements across a range of different waveforms. The DOS1102 compared very well with the Rigol during my testing. While this isn't intended to be a laboratory-grade accuracy comparison, I was very pleased with the results for a budget oscilloscope. Seven-Hour Test One of the most important tests for me was using the oscilloscope for an extended period. I used the DOS1102 for approximately seven hours during a full day of testing, alongside my normal test equipment and carrying out a variety of measurements. Throughout the testing, it performed well and I experienced no problems with its operation. This gave me considerably more confidence in the instrument than simply switching it on and carrying out a few quick measurements. Who Is It Suitable For ? In my opinion, the DOS1102 would suit a wide range of users, from hobbyists and students through to electronics repairers, technicians and engineers who need a compact instrument for quick measurements. It has enough features to make it useful for someone learning electronics, while also offering functions that more experienced users will appreciate. Overall Verdict Overall, I am very happy with the HANMATEK DOS1102. For an affordable 110MHz oscilloscope, it offers an impressive selection of features, including Maths, FFT, Trigger Holdoff, cursor measurements with cursor locking, horizontal zoom and push-function control knobs. The build quality is good, the controls are straightforward, and after putting it through a full seven-hour testing session, I have been very impressed with its performance. For the money, I think HANMATEK has produced a very capable little oscilloscope. It is more than just a basic entry-level scope, offering several features that make it considerably more versatile than I expected at this price. I am very happy with my purchase and would have no hesitation recommending the DOS1102 to anyone looking for a capable and affordable oscilloscope.
