[美國直購 ShopUSA] 回環插頭 USB3.0 Loopback Plugs High Quality Loopback Plugs for USB 3.0 Troubleshooting and Testing _d18 PS.圖片僅供參考,商品以實物為准! USB 3.0 Loopback plugs are one of the fastest methods to diagnose, troubleshoot and load test your PC's USB functions. When used with compatible PassMark testing software (see below) is it possible to: •Quickly check if a USB port is powered; •Measure the voltage of the USB port, no driver is required for this as the plug will display this information directly on the LCD screen (accurate to ±0.1V) •Check that data can be sent and received from the port; •Check USB errors rates and transmission speed (up to 5Gbits/sec ) in Windows; •Measure the level of recovered data (retransmitted frames); •Verify that the system remains stable under long periods of load; •Test that USB support in Windows or Linux is available; •Test self powered USB hubs and PC ports function correctly; •Check USB cabling; •Concurrently check multiple USB ports at the same time; •Benchmark your PC's USB ports & hubs; and •Check if your PC ports are super speed 5Gbits/sec (USB 3.0), high speed 480Mbits/sec (USB 2.0) or full speed 12Mbits/sec (USB 1.x) Active loopback plugs are the quickest, most effective way to verify that a PC's USB ports are working correctly. The Red, Green and Yellow LED's on the front of this USB adapter plug provide a quick visual indication of I/O activity and if the USB bus is powered. This will dramatically improve the troubleshooting and diagnostic ability of computer technicians and system integrators, who have previously been working blind. In benchmark mode (Windows only), the device is capable of reaching the maximum defined transfer speed for USB3.0, 5Gbit/sec. Note: Testing has shown that most PC's can not attain speeds much above 2.5 Gbits/sec and performance will vary depending on your motherboard, CPU and other USB devices connected to the PC. Up to 10 of these USB test plugs can be simultaneously connected to a PC providing that free USB ports are available on the PC or on a down stream hub and sufficient power is available. These plugs are unique! They are the only true USB 3.0 loop back adapters on the market and have been especially designed for use with our BurnInTest Professional, BurnIntest for Linux software package or USB3Test stand alone software (supplied with the plug). They do not require an external power supply and do not require a connection to any other port on a PC. Each plug also has its own serial number stored in EPROM, on the plug, so it is possible to identify each plug when multiple plugs are connected. Each plug also contains its own CPU and executes its own firmware.
