Not bad, it works. several features are missing. It is a very basic device, a Multimeter, which has been extended with a rudimentary oscilloscope function. I have only tried measuring the voltage, it has two settings, mV and V. In the mV position. At the 30mV/Div setting, the frequency is only 15kHz Above that, 150kHz up to 300mV/Div In the V position. the promised 1MHz is there throughout. The problem with the whole thing is that the time base is so slow that I think it can be used normally up to 500kHz signals. 2.5 us/div Above it, the signal is so dense that it is difficult to see properly. A few things I really miss. The sampling could have been higher, 5MSa/s is quite low, they could have gone to at least 100 or 200 MSa/s. Among the functions I really miss is the bluetooth connection. Which is already included in the current clamp version, but I have no information on whether it also works in oscilloscope mode. Save the waveform in a file, not just as an image. More memory for the oscilloscope part. if the internal storage space is small, only 20 images are saved, it is possible to expand it with a memory card. The trigger is located in the middle, it cannot be moved to the side. The time base could have been slower, for example 1000s/div I have a few more ideas. good, but it would have been better if it had been better.
magnifico
