With the use of PC-based and PC-interfaced test instruments becoming more and more widespread, K Measure has found that the need for USB port isolation is becoming a concern for engineers. To this end the company supplies a solution in the form of a USB 2.0 compliant port isolator that provides 1000 V isolation to protect a USB port. This device is designed to protect a computer’s USB port when connected to external measurement instrumentation.
With all instruments this protection is not a requirement, but in the case where a very high voltage spike is being injected into the instrument, it might relay the spike to the USB port also, damaging it in the process. In such a scenario the isolator will prevent the computer’s USB port from being damaged. Considering the cost of computers, it can prove well worth investing in a USB port isolator to protect these valuable assets.
