what is the "toy" capable of? / Tools / iXBT Live
Of course, these cannot be serious models for professionals; but let's figure it out, everything is completely bad there, or not at all ?!
Let's take the popular DSO150 pocket oscilloscope as an example.
By the way, it is also known under the names DSO Fnirsi 150, DSO Shell and DSO 150 - these are all synonyms.
The image is from the seller's official page (as it turns out later, this is not exactly the same as from the manufacturer's website). All pictures in the review are clickable.
The oscilloscope is sold on Aliexpress in several versions.
One option - fully assembled and "ready to use"; the second option - in the form of body parts, boards and a scattering of parts for soldering; and the third option - body parts and boards with soldered parts. I chose the last option, in which you just need to put everything together correctly without soldering (too lazy, you know).
I bought it all here.
The price of such a kit at the date of the review with delivery to Russia is about $24.
Packaging, kit composition, assembly and appearance of the DSO150 oscilloscope
The oscilloscope arrived in a foam box, conscientiously wrapped with film and tape.
This is how it looks after being stripped of the outer covers:
Styrofoam is a good protection against troubles on the way; nothing inside was damaged.
The box itself contained the following set of parts for assembly:
Assembly did not go smoothly.
I really didn't want to fit the encoder handle on its axis. I had to use brute physical force (this helped to dress her, although not quite to the end; it was scary to break something).
Perhaps a better option would be to use a soldering or cosmetic hair dryer to heat up the shaft and handle (but be careful not to melt the plastic parts).
In addition, it was not possible to fit the top cover and bottom so precisely that there was no gap between them at all. True, the remaining gap of half a millimeter can even be called decorative.
Let's look at the build result.
Top view:
Bottom view:
Two diagonal views:
Bottom side view:
View from the top side:
Here (on the top end) there is an input switching slider (closed / open / ground), a 1 kHz calibration voltage flat contact, and, in fact, a BNC connector for signaling.
In general, the appearance of the oscilloscope turned out to be quite decent, and does not particularly resemble a “toy” or a training copy (like its historical predecessor DSO138 in a transparent case or even in a frameless form).
The case is also well sealed against the penetration of small external objects and dirt (unlike, for example, DSO188).
But what is not good is the need for external power supply (there is no built-in battery). True, there is still free space inside the oscilloscope to place the battery and the necessary “strapping” there, but this is not for lazy people like me. A discussion of how to install internal power is on the forum of the official manufacturer (JYE Tech).
DSO150 oscilloscope printed circuit boards and circuitry
Finally, we have come to the electronic "stuffing" of our oscilloscope.
This filling consists of two boards: analog and digital.
Analog board - small. but very full of components:
Here I am glad that the marking of all elements is left readable, and even duplicated by inscriptions on the board.
It happens that some particularly unscrupulous Chinese manufacturers, on the contrary, carefully overwrite the markings in order to make it difficult to repair products. But this is not the case, fortunately!
Moreover, schematic diagrams can also be downloaded from the official page of the oscilloscope on the manufacturer's website (at the bottom of the page, in the "Documents" section). In general, this can already be equated to a miracle !!!
The main element on the board is a TL084C quad opamp with FET inputs. He is responsible for receiving and amplifying the signal.
Two analog switches provide gain scaling: HC4053 and HC4051.
All the microcircuits listed above require a bipolar power supply, and the device is powered by a unipolar one. Accordingly, the ICL7660 converter creates a negative polarity for the internal power supply, and stabilizes the power supply 78L05 (+5 V) and 79L05 (-5 V).
The green trimmers on the top of the board are responsible for adjusting the input capacitance (required for the correct display of signal edges).
Instructions for setting up are in the attached paper document (you need to set up, of course, before installing the boards in the case; or in the case, but without the top end cap).
Now let's examine the digital board, first - the view from the side of the screen:
Here - the encoder knob, buttons and screen. The screen cable under it is soldered directly to the board. This will make it difficult to change the screen if you "bang" it. True, after assembling the oscilloscope, it will be quite difficult to do this, because. the screen is located in the recess. But accuracy in handling is not canceled.
The screen is not dimmable, but its brightness is set to a moderate level sufficient for comfortable viewing in typical applications.
Screen viewing angles are different vertically and horizontally.
The horizontal viewing angle is not wide, even with small turns to the right and left the screen becomes noticeably pale.
When turning up and down, on the contrary, the image remains bright and contrasting even at large turns.
The view of the digital board from the side of the elements is much more interesting:
Here, first, let's pay attention to an important organizational point: in the white frame located in the lower left corner, there should be a board number, but it is not there!
In accordance with the manufacturer's instructions "How to distinguish a non-original oscilloscope from the original" (link), we conclude that this copy is not original.
What follows from this? It follows that its firmware is unlikely to be updated. In the best case, the new firmware simply will not be installed (the manufacturer will not give a code for installing it), and in the worst case, the oscilloscope may “brick”. Is it possible to live with the firmware as it is - let's figure it out.
Let's get back to the board.
Here we see the "heart" of the oscilloscope - analog-to-digital processor STM32F103C8T6.
Next to it is an 8 MHz quartz; but the processor has its own frequency multiplier and runs at 72 MHz.
This is not much, but at a low frequency and energy consumption is less.
The processor is made according to the "all-in-one" principle: RAM and ROM are also in the processor. It also generates an image to be sent to the display.
In addition to the processor, the board has two more "mikruh": flash memory with a serial interface and a 3.3 V linear regulator that provides power to the processor.
To finally clarify the situation with the software (firmware) version, let's look at the screenshot at the time of loading the oscilloscope:
Thus, the oscilloscope works under firmware version 062. This version is not the latest, but it is quite well-developed and should not surprise you with strong glitches.
Testing the DSO150 oscilloscope
We figured out the mechanics and circuit, let's move on to practical testing. The FY6800 generator was used for testing.
Let's start with the elementary and standard: sine, 1 kHz, 5 V peak (you can't think of a standard one!):
We first pay attention to the many parameters measured by the oscilloscope in real time, right along the signal path.
In addition to the measurement results, the oscilloscope shows its own operating modes (above the waveform and below it).
If the measurement data interferes with the waveform, it can be removed from the screen.
And now let's check the measurement accuracy.
The oscilloscope showed a voltage swing (Vpp) of 5.15 V. This is a good result, since it fits within the stated error of 5%. True, with a decrease in the amplitude of the signal, the accuracy also decreases, but this corresponds to the theory of the issue.
Now let's look at the frequency. The oscilloscope showed 973.303 Hz. For measuring frequency, such accuracy is simply not good enough.
Checking the frequency measurement with a different time scale showed a much more decent result:
Here the oscilloscope measured the frequency exactly: 1 kHz.
Most likely, the device calculates the frequency primitively, according to the number of times the signal crosses the trigger level for a period equal to the buffer filling.
The more periods fit into the buffer, the more accurate the frequency measurement is.
Let's move on.
Testing the bandwidth at minus 3 dB showed a result approximately corresponding to the declared in the parameters: about 220 kHz.
Now we feed a 20 kHz rectangle and check the fronts:
In general, the fronts of the “rectangle” can be assessed as good. But there is also an interesting feature: the negative front is steeper than the positive one; which has a fairly smooth "rounding" at the top.
Similar effects will be observed on other oscillograms of the "classic" series:
Now let's move from theory to practice and look at a couple of real oscillograms.
As a test object, a switching power supply was chosen, giving voltages of + 5 and +12 V with an output current of 3 A for +5 V output and 2 A for +12 V output. voltage rectifier +5 V.
Option 1, power supply without load:
Option 2, with a load of 1 A at +5 V output:
Oscillograms can be used to estimate the frequency of operation of the switching power supply converter (a little above 50 kHz) and the magnitude of the forward and reverse pulses .
It is useless to look at the signal frequency according to the measurement readings of the oscilloscope itself for signals of such a complex shape - it can show anything (and quite legally).
As a result of this chapter, it must be said that electrical processes with a frequency of about 50 kHz are the limit when you can really track the waveform using this oscilloscope. For higher frequencies, there will be too few samples per signal period to judge its real shape.
Strobo effect
Users of digital oscilloscopes are probably already aware of this interesting effect. But for amateurs and professionals who have so far used only analog “tube” oscilloscopes, this may be news. :)
By the way, analog oscilloscopes are not an anachronism, they are still successfully produced and used. But, of course, the lack of mathematical processing in them, as well as their large weight and dimensions, do not contribute to their popularity.
I will start approaching the problem from afar.
In Wikipedia, in the article "Oscilloscope", there is an interesting passage about the shortcomings of digital oscilloscopes (underlined):
This problem (displaying non-existent signals instead of real ones) occurs due to the stroboscopic effect.
Stroboscopic effects occur when the number of signal samples per period becomes too small.
According to the classical Kotelnikov's theorem for radio engineering, any signal can be absolutely accurately restored if its sampling frequency is at least twice the upper frequency in the signal spectrum.
But this is valid, relatively speaking, for signals of infinite length and after processing by appropriate algorithms, and not in real time.
And in real time, the signal "loses shape" so seriously that it becomes completely different from itself.
So, for example, our oscilloscope shows a sinusoid with a frequency of 246 kHz:
The observer sees a non-existent amplitude-modulated signal on the screen.
In fact, a pure sine wave is fed to the oscilloscope.
Sometimes even experienced reviewers write that at a high frequency, an oscilloscope shows a signal with a corrupted shape, jumping amplitude, etc. In fact, such a mapping of the signal can be quite legal from a physical and even from a geometric point of view.
Since switching the time scale on the oscilloscope also changes its sampling rate, the user can see these effects even at fairly low frequencies.
For example, the following waveform was taken with a square wave frequency of 124 kHz; but due to the fact that the sampling frequency at a scale of 0.2 ms / division decreased to 50 kHz, the signal on the screen degenerated into a rectangle with a frequency of 1 kHz:
It will seem to the observer. that he sees a rectangular signal with a frequency of 1 kHz; and only the fronts that are unnaturally tightened for such a frequency will be a hint that "something is wrong here."
The existence of this effect must be taken into account when working with digital oscilloscopes (ie, choosing the right horizontal sweep parameters).
This effect can also be used to advantage: there are special stroboscopic oscilloscopes for studying periodic processes in the microwave, but these are far from “general civil” devices.
Conclusion
The oscilloscope tested is one of the cheapest ones, commonly referred to as "toys" or "display meters".
However, it can be used for serious purposes, if you do not set impossible tasks for it.
For example, for testing and tuning class D amplifiers, it is not suitable: there the PWM pulse frequency starts from 400 kHz.
On the other hand, there are almost no obstacles for working with “ordinary” amplifiers (class A or AB); except that it may not show the self-excitation of the amplifier if it happened at a high frequency.
It can also be used to work with switching power supplies with a PWM frequency of up to 50 kHz (and this, however, is not always the case; sometimes even in typical power bank controllers, the frequency can be up to 100 kHz).
