Osciloscopio fnirsi 1014d - generador de señal DDS de osciloscopio digital en dos en uno, ancho de banda de 100 MHz de 2 canales 1gsa / s tasa de muestreo

Product Information

Connect the probe clip to the negative extreme of the power output, and the probe is connected to the positive extreme of the power output, and wait for about 3 seconds. When the yellow line and the left yellow arrow position are in the same position, wait until the position is in the same position Gear selection: the communication signal of automobile is generally lower than 20V, and the maximum test for 1x gear is 40V, so it is enough to test the vehicle communication signal signal with the 1x gear (both probe and oscilloscope are set to the 1x gear).

Connect the probe clip to the negative battery or the negative DC electrode, and the probe to the battery or DC positive pole Targeted high intelligent decoding algorithm, the encoder life is infinite, and intelligent anti-burn function, 1x Can withstand up to 400V withstand voltage.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. Memory depth 240kbit instead of bytes or samples, which both Davey Jones and this review missed to mention. Answer: the city power 220V is a symmetrical AC signal, the positive peak voltage (maximum value) is +31 Ov, the negative peak voltage (minimum value) is -310v, so the peak peak value is 620V, the switching parameter is the effective value. At this time, it is often said that the voltage of 220V, the effective value of the municipal voltage fluctuates from 180 to 260V, so the peak VPP is in the range of 507-733v 14: Why is the measured voltage of 220V not a standard sine wave, there is distortion? 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:

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. Started implementation of trace data capture. This will take a bit of time. A lot of code to work through. probe (such as ultrasonic welding machine, ultrasonic cleaning machine, etc.) or even 1000x probe (such as high-voltage end of high-frequency transformer, coil of induction cooker, etc.) must be used to measure high-frequency and high-voltage signal Solemnly remind 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, Effortless Data Transfer: Integrated USB interface ensures seamless data sharing and secondary analysis on computers.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. Gear selection: the infrared remote control signal is generally 3-5v, and the maximum test for 1x gear is 40V, so it is enough to test the vehicle communication signal signal with the 1x gear (both the probe and oscilloscope are set to the 1x gear).

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. 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? 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? Gear selection: crystal oscillator is easy to stop oscillation after encountering capacitance. Input capacitance of 1x probe is up to 100-300pf, 10x gear is about 10-30pf, and it is easy to stop vibration in 1 x gear, so it is necessary to set 10x gear, that is, both probe and oscilloscope should be switched to 10x gear (probe and oscilloscope are set to 10x gear)Firmware update (This means both code within my version as creating an actual firmware update that can be loaded on a scope) All the top menus are implemented and except for the main manu functional. The main menu allows for opening the system settings menu. The hardware architecture uses an Arm + FPGA + high-speed ADC design. As in my initial assumptions, the oscilloscope uses the ANLOGIC EF2L45LG144B FPGA and two ADC with illegible markings used to process digital signals. Based on comments on EEVBlo, those should be AD9288 ADC chips, and we can see the display part relies on the Allwinner F1C100s ARM9 processor to drive the TFT screen. FNIRSI 1013D design comparison

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 waveform view screen with waveform view almost done. (Still needs displaying of the trace data) This device is fitted with a built-in DDS function signal generator, enabling it to produce 14 kinds of standard function signals and a customizable chopping signal. Plus, it’s capable of storing up to 1000 customized cut-off signals for future use. Enhanced Safety of FNIRSI 1014D 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.Built-in DDS Signal Generator: Supports 12 different kinds of function signals, offering comprehensive signal generation for a wide variety of applications. 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? Also tweaked the touch panel speed after changing the delay function to assembly code. It is now around 200KHz
