Let me try, I'll let you know if I happen to crack it. However, tt seems to be a difficult circuit and I don't think I would be able to design this one. LED indicates power supplied via upstream USB port. Yes it's definitely an interesting concept to investigate. These isolators are USB bus powered and provide up to 100mA of current to attached downstream devices. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. Thank you, John Waterman Analyzing the Circuit Idea Might this be a useful DIY project for the pages of Homemade Circuit Projects? An example of such an isolator is shown here:Ī less costly alternative to many of the other the eye-wateringly expensive isolators also shown on EBay might be really useful. Thanks for your input and sharing your experience. And also about what the comparative sonic impact difference between cables to the device and from the device to the DAC might be. Power is provided from the computers USB port, however an external power supply can be connected to the isolator if your USB device has a high current consumption (400mA or more). Curious about the effectiveness of galvanic USB isolation - in particular JCat USB Isolator vs iFi micro iUSB 3.0. One answer to this problem would be to place a USB Isolator between the usb input of the test circuit and the PC. The ADUM4160 makes this USB isolator compatible with both low speed (1.5M) and high speed (12M). I had heard that one must use extreme caution when placing the oscilloscope probe earth of this (and any) oscilloscope on the test circuit if that test circuit is also brought to mains earth potential by plugging it in to a USB port to power it.Ī wrong move could zap the test circuit and possibly the oscilloscope 🙁 A video by Dave of EEV Blog explains the dangers more clearly than I can. USB port isolator based on an Analog Devices ADuM3160 to protect computers against over-voltage spikes, ESD pulses and to avoid ground loops.
USB ISOLATOR PC
Some time ago I purchased a Digitech 40MHz Dual Channel USB Oscilloscope that i would now like to learn to use with a PC via USB.
