Product Information

thanks for “no options for freezing the display”, because i am trying to understand what i’m missing with my middle of the road digital scope and i think that might be the crux of the matter? 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 remainder of the user interface first. This concerns the moving of the traces and the cursors and the adjusting of the time base setting.

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?does with it. If this does not yield what is needed a reverse engineering of the FPGA might be needed, but is far more difficult. High-Resolution Display: Features a fully fitted 7-inch 800 * 480 resolution color TFT LCD display, providing a bright, high-contrast view of your waveforms. Been busy with the SD card part of the code and managed to get FatFs into the mix and filled in the functions for talking to the card.

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 Found how the scope display's the menus. It uses a lot of bitmaps that are copied to the display instead of printing text.

Ikascope WS200 Oscilloscope and ScanaQuad SQ50 Logic Analyzer & Pattern Generator Review – Part 1: Unboxing 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. Implemented channel 1 menu handling and are now able to change the settings for it. Found functions that control the FPGA based on the settings 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. The process of reversing the complete software is still ongoing. Focus at the moment is on the display library.

Also, this Tektronix technical brief on the subject (hosted by the Electrical and Computer Eng. dept. at UBC): https://people.ece.ubc.ca/robertor/Links_files/Files/TEK-Understanding-Scope-BW-tr-Fidelity.pdf FNIRSI 1014D offers advanced analysis tools including FFT viewing function for estimating harmonic components of signals and Li Shayu’s graphic display function for amplitude, frequency, and phase comparison of two groups of signals. Features: Channel 1 signal input port, the measurement range is 0 ~ 40V peak to peak, pay attention to the maximum tolerance of 400V peak to peak withstand voltageFunction 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.

Took a look at that part of the user interface code and it is messy, but it starts to make some sense. The teardown shows there isn’t much on board and the design doesn’t seem very sophisticated. Granted, the scope is cheap, but maybe it is just too cheap. [Kerry] wasn’t impressed and, from what we saw, we weren’t either. His exact quote was: “I wouldn’t touch this ‘scope with a ten-foot pole.” All the above is true. But just as with lathe, scope, knife, camera – bad tool is better than no tool.

Most of the FPGA functions have been discovered and described. With the emulator the sequence of commands have been traced. Press the [auto] button once to display the waveform of the crystal vibration tested. If the waveform after automatic adjustment is too small or too large, the waveform size can be adjusted manually by knob PWM signal measurement of MOS tube or IGBT
