Product Information

Another fantastic unit for this entry-level line is the Owon SDS1102 or the Owon SDS1104 ( see my review) for a 4-Channel oscilloscope, which despite having a slightly higher value, already has functions that do not exist in this one. , take a look at the review I did.

Most sensitive range 50mv/division, while any “normal” scope at least goes down to 5mv/div, and the trend is to more sensitive (limited by noise). With a normal 1:10 probe this would be 500m/div which is a serious limitation. (You do not want to use any oscilloscope without the 1:10 probes) User-Friendly Operations: One-button auto and cursor measurement functions simplify complex readings. Firstly, the oscilloscope is set to auto trigger mode (auto trigger mode is default after startup), and auto trigger mode is used to test the cycle signal (50Hz of household electric power belongs to the periodic signal) trigger mode indicator, divided into auto, single and normal; auto is automatic trigger, sinle is single trigger and normal is normal trigger

Answer: if the input signal is a symmetrical AC signal (such as domestic 220V), the AC coupling or DC coupling waveform are the same. If it is an asymmetric AC signal or a DC pulse signal, the waveform will move up and down when the coupling is switched 7: Why does the waveform run up and down when testing the signal, and can’t see the waveform only see multiple online and offline beats? The ‘scope looks like a lot of other inexpensive ‘scopes, but you can see some concessions to price. For example, the encoder knobs don’t have a push button function, making the scope more difficult to operate. While the specs are relatively modest, [Kerry] wasn’t sure the instrument was even living up to them. Dirt-cheap digital scopes have, in my experience, too many issues with aliasing, such that even the cheapest analog scope with one channel is more useful. and in this repository there is a new firmware file for the scope. This is for the scope version with the W25Q32 flash chip (32Mbit). This is also the scope that has the problems with the reversed coordinates when the touch panel is replaced with one that uses a GOODIX GT915(7) touch panel controller.

The 50mV/Div is another quite significant limitation. That turns into 500mV/div with a 1:10 probe, which you need to get a decent bandwidth. And that the scope isn’t sampling at the claimed 1 billion samples per second, but rather 1 fifth of that.There’s now even PeakTech 1400 series which at its lowest end with cut down specs beats Fnirsi on price. I don’t know where they come from, they seem to have Owon-y feel but I haven’t seen an equivalent model there. Answer: first, it is necessary to ensure that the trigger mode is auto automatic triggering. If it is still 0 in auto mode, press [auto] button once. At least a clear and complete periodic waveform is displayed on the screen, and the waveform should be triggered (the green arrow indicates that the position is fixed between the wave shape and the wave shape without shaking). The data of frequency value is correct 5: Why is the duty cycle 0?

Press the [auto] button once to display the measured PWM waveform. If the waveform after automatic adjustment is too small or too large, the waveform size can be adjusted manually by knob Signal generator output measurement Connect the probe clip and probe to 2 wires of household electric power without distinguishing the positive and negative polesFNIRSI-1013D provides a one-button auto-adjustment function, avoiding tedious manual adjustment, and the dual-channel display facilitates real-time waveform comparison. In addition, the oscilloscope provides three different trigger modes: automatic, single, and normal. The automatic mode can be used to process sudden non-periodic mutation signals, the single mode can be used to process non-periodic digital logic signals, and the normal mode can be used to process periodic analog signals. Function Signal Generator: Built-in DDS function signal generator and industry's original chopping output (@2.5VPP), all signal frequency steps are 1HZ, support 14 kinds of standard function signals and a customizable chopping signal, chopping the output divice intercepts part or the whole part of the complex signals measured by the oscilloscope as the output signal of the signal generator, which can store up to 1000 customized chopping signals. Short time base settings 50mS-10nS. (This is partially implemented. Channel 1 data is fetched and displayed raw. Only part of the processing is implemented.) Firstly, the oscilloscope is set to auto trigger mode (auto trigger mode is default after startup), and auto trigger mode is used to test the periodic signal (the sine signal of crystal resonance belongs to the periodic signal) Answer: the trigger voltage needs to be adjusted, that is, the green arrow on the right needs to adjust the green indicator to the top and bottom of the waveform. The waveform is triggered and fixed, or the setting menu is entered to turn on “automatic 50%.” 9: Why can’t we capture sudden pulse waves or digital logic signals?

Gear selection: the output voltage of inverter is similar to that of household electricity, with peak peak voltage above 500V, the highest measurement of 40V in 1X, 400V in 10x and 4000V in 100x gear. The default standard probe is 10x high voltage probe, and the peak value of 400V can only be measured at the highest Therefore, 100x probe shall be provided by itself, and then set to 100x gear, that is, both probe and oscilloscope shall be switched to 100x gear With a built-in high-voltage protection module that can tolerate up to 400V continuous voltage, you can now focus on your work without worrying about accidental oscilloscope burnings. Digital Oscilloscope One Button Auto & Cursor Measurement Function with 100mHz High-Performance Sampling: Achieves a real-time sampling rate of 1GSa/s, ensuring detailed signal representations. We can clearly see there the waveform of the pulse”. Euh, I just see some garbage because of too low sampling rate. If I look at this review, it does not test the capabilities and flaws of this fnirsi thing (I won’t call it an oscilloscope) He just puts a few of the simplest repetitive waveforms into it, and then concludes it’s able to show some picture on screen. And Indeed, this fnirsi is capable of putting something on the screen that (most often) resembles the signal it’s measuring. The trouble with this thing is that you can’t trust it because it hides to much and there is too much you can’t see, and that is why it’s bad.

All reviewers also seem to take it out of the box and put some test signals into it. I have never seen someone actually using it for serious work for a few months and then making a review.
