Hi, I am using analog discovery 2 usb oscilloscope which has 2 channels. But my experiment requires 4 channels to read the data simultaneously. So do you have any usb oscilloscope which has 4 channels? Or can I buy two analog discovery 2/3 and then use one waveform software to run 4 channels simultaneously? If so, can you please tell me how to do that? Do you have any video to make four channels using two analog discovery 2/3? Please let me know as soon as possible. Thanks.
