All the above is true. But just as with lathe, scope, knife, camera – bad tool is better than no tool. 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) The big artifacts that look weird to Kerry Wong are caused by averaging. My Rigol DS1052E can show very similar artifacts if you turn on averaging and average a lot of traces. The scope did start up fast and had responsive controls, which is good. There were some display oddities as the horizontal sweep changed. The scope claims to have 100 MHz bandwidth. However, it appears this is vastly overstated. In addition, there was some measurement offset as frequency increased.

SO ALWAYS make a copy of your own flash first and compare the data with what is in the new firmware Connect the probe clip and probe to the output end of 2 lines of the amplifier without distinguishing the positive and negative poles For FNIRSI the next logical step should be the launch of a bench oscilloscope, and that finally happened with the FNIRSI 1014D.

The weird transition which is a clear indication of averaging (i.e, you will never see any glitch). FNIRSI 1014D digital oscilloscope is equipped with a high-definition 7-inch LCD boasting an 800 * 480 resolution. The larger display area gives you a more detailed look at your signals and their behavior. Storage and Connectivity: 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; Answer: adjust the trigger mode to “Normal” or “Single”, then adjust the trigger voltage and time base and vertical sensitivity, and finally touch the pause. 10: Why does trigger voltage regulation not respond?

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. Answer: battery voltage signal is stable DC signal, there is no curve waveform, in DC coupled mode, and then adjust vertical sensitivity, there will be an upward or downward offset straight line waveform, if it is AC coupling, no matter how to adjust, there is no waveform. 12: why do we measure the 220V power frequency 50Hz wave? Switching down to 50nS/div kills the program, but this most likely has to do with the fact that the 50nS processing is only partialy implemented. again confirming the earlier findings. Writing the emulator was worth it. Without it I would not have gotten this far. It also allows for testing the code The BEST scope IMHO is the Tek 2465 : best analog for the price with a digitally-assisted interface, a breeze to use ! It is the culmination of an era at Tektronix, more than 20 years ago. Available too with ultra-bright screen for spotting transients and GPIB.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?

Answer: first, it is necessary to ensure that the trigger mode is auto automatic triggering. If it is still 0 in auto mode, it may be that the trigger is not adjusted to the waveform. After the trigger line is adjusted to the waveform, the waveform will be fixed. Moreover, the data of duty cycle will be correct only after at least one clear periodic waveform is displayed on the screen 6: Why is AC coupling the same as DC coupling waveform?With the current state of electronics, you simply can not make a decent scope for that price. You can get a Hantek or Owon for just a little bit more, and those at least don’t lie (as much) to you. Or get a handheld with small LCD (so there is some budget left for the front end). Press the [auto] button once, the waveform output by the generator will be displayed. If the waveform after automatic adjustment is too small or too large, the waveform size can be adjusted manually by knob Measurement of domestic electricity at 220V or 110V All the top menus are implemented and except for the main manu functional. The main menu allows for opening the system settings menu. Capture waveform: Capture waveform output is to capture part or the whole part of the current displayed waveform as the output of signal generator. The captured signal can be saved to the system, and up to 1000 groups of captured signals can be saved.

We’ve heard of the FNIRSI 1014D scope, but we’ve had the impression that it might not be a great scope, although it is economical. [Learn Electronics Repair] had heard from another YouTuber that it was “a piece of junk.” However, he wanted to look at it compared to another inexpensive scope, the Rigol DS1052E. His results were different from what we usually hear. To be clear, he didn’t think it was a perfect scope, but he did find it very usable for his purpose.High Efficiency One-button AUTO: Features an efficient one-button AUTO, alongside a one-button waveform storage and screenshot function, for ease of use. FNIRSI-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. High Bandwidth and Sampling Rate: Offers 100MHz * 2 analog bandwidth and a sampling rate of 1GSa/s (1X = 5MHz, 10X = 100MHz), ensuring accurate signal representation. With built-in 1GB storage, you can store up to 1000 screen capture images and waveform data groups. Furthermore, the device comes with a USB interface for easy connection with your computer for secondary analysis or data sharing. Advanced Analysis Tools: At the moment working on the USB interface.
