it writes the FPGA command 0x0D with the value 0x000007D0, just as what I found in my explorations:-) 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? The input coupling mode of channel 1 has two options: DC and ac. DC means DC coupling and AC means AC coupling Press the [auto] button once to display the waveform of the inverter. If the waveform after automatic adjustment is too small or too large, the waveform size can be adjusted manually by knob Measurement of power amplifier or audio signal Effortless Data Transfer: Integrated USB interface ensures seamless data sharing and secondary analysis on computers.

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 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. Lissajous figures graphic display function can be used to determine the amplitude, frequency, and phase contrast of two groups of signals. Also found more about the working of the color handling. Uploaded the Ghidra archive with the latest findings. Still a long way to go.Found that the original code uses start and end coordinates to define a rectangle were as my code uses positions and dimensions. 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?

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; Wrote a lot of the display functions and the touchpanel interface functions. Now I found a lot of the variables used in the scope, 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.”SO ALWAYS make a copy of your own flash first and compare the data with what is in the new firmware The emulator is functional and the working of the system is slowly being revealed. Quite a few commands to control the FPGA are now known.

Press the [auto] button once to display the waveform of the household electric power. If the waveform after automatic adjustment is too small or too large, the waveform size can be adjusted manually by the knob Power ripple measurement You can get regular decent oscilloscope for around EUR300 nowaday’s. Sure, it’s twice the money of this toy, but my guess is that this thing will cause so much frustration that you want to buy a “real” scope within a year or two, while such a EUR300 scope does not have the glaring pitfalls of this thing and may well give you good service for years to come, and it’s also more likely to be sold second hand for a decent price. Take for example the old Rigol DS1052E, second hand prices seem to be quite near the new price ???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, At the moment working on the USB interface. Managed to get an emulation of a CH340 device working and are basing the mass storage device Integrated analog audio codec with 2-channel DAC and one ADC, up to 192KHz DAC sample rate, up to 48KHz ADC sample rate
