Measuring the universal serial bus usb march 8 2017 by david herres 1 comment the average person on the street computer literate since childhood is familiar with the look and feel of a usb cable and is generally aware of the difference between types a and b plugs that go into host and peripheral ports respectively.

Impedance in the case of cables is ac impedance. You can use the same technique to send a short pulse through the wire and check the. 1 2 scope the information provided in this document serves as a guideline for design development and voluntary compliance testing of usb connectors and fabricated cables assemblies as well as defining mechanical electrical environmental and performance characteristics. This avoids internal reflections from impedance mismatch.

A supplement to the usb standard introduces on the go mode which enables a usb product to operate as either a host or a device depending on which kind of controller is in the other end of the cable. Thus a 50 ohm cable or a 75 ohm cable. Each of the loops represents a possible fault scenario. I have written an article about measuring the velocity factor of a cable.

Host or device with hub being a special version of a usb device. For the determination of parameters for your single circuit line you inject a test current into several different test loops. Impedance measurement on power cables. Usb can be operated in 2 different modes.

The following will explain the difference with tdr when an acm2012 900 2p filter was used on an ic evaluation board and when a common mode filter with a low characteristic impedance was used.
