Generous Storage Options: 1GB built-in storage accommodates up to 1000 screenshots and waveform data sets for easy recall. 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. on this code. Got some crude implementation to communicate with my Linux machine. Still needs a lot of work done to make it a proper driver, Took a look at that part of the user interface code and it is messy, but it starts to make some sense.

Features

Firmware update (This means both code within my version as creating an actual firmware update that can be loaded on a scope) When the two channels are used at the same time, the ground clamps of the two probes must be connected together. It is strictly forbidden to connect the ground clamps of the two probes to different potentials, especially the different potential terminals of high-power equipment or 220 v. otherwise, the oscilloscope motherboard will be burned. Because the two channels are grounded together, connecting to different potentials will lead to the short circuit of the internal ground wires of the motherboard, and all oscilloscopes are same; If you only want to see some simple signals, then indeed this thing may be “usable”. If you want to do some more with electronics, then soon you will be mislead by the fnirsi thing and you will probably be wasting hours of your time before you even realize it’s the fnirsi that gives you a distorted view of your signals, and then you’re still guessing what is really happening, and that is not what you want to spend your time on while learning electronics. 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.

Lissajous Graphic Display & FFT Viewing: Lissajous graphic display function can be used to compare the amplitude, frequency and phase of the two sets of signals. FFT viewing function can roughly estimation of the harmonic content of the signal. Equipped with high-efficiency One-button AUTO, and one-button waveform storage and screenshot function. Customizable Screen Settings: Adjustable brightness levels cater to varying user preferences and environments. But let me say again, if you don’t need math functions or many features that you’ll never use in your life because you basically mess with arduinos, raspberries pi, esp32 or others and little else, don’t spend more money, in my opinion this will be enough. Compact & Portable: Designed for both stationary and on-the-go usage, making it perfect for fieldwork.There is progress in getting to an open source version. The bootloader is reversed to a C project and it is working. in between the different actions, of which only one is realy needed. Between the writing and the reading it needs a fair amount of time. Not for the FPGA, Firstly, the oscilloscope is set to normal normal trigger mode (auto trigger mode is default after startup). Normal trigger mode is specially used to measure the non periodic digital signal. If Auto trigger mode is used, it is impossible to grasp the non periodic signal Memory depth 240kbit instead of bytes or samples, which both Davey Jones and this review missed to mention. Gear selection: first, you need to buy 100x probe; household electric power generally 180-260V, peak peak voltage is 507-733v, the maximum measurement of 1x is 40V, the highest value of 10x is 400V, 10Ox is 4000V, and the default standard probe is 10x high voltage probe, and the peak value of 400V can only be measured. 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
