Keysight Technologies Inc. High speed USB host test fixture kit
To perform the signal quality test on USB 2.0 hi-speed hosts, Keysight recommends using the E2667B USB 2.0 hi-speed host test fixture kit along with the DSOXUSBSQ USB 2.0 Signal Quality test option on a 1.5 GHz bandwidth 4000 X-Series oscilloscope. Testing hi-speed hosts using a programmed test pattern based on USB-IF standards only requires that you connect the D+ and D- signals from the test fixture to the oscilloscope¿s input channels using SMA cabling along with the appropriate SMA-to-BNC adapters.
The Keysight E2667B High-Speed USB Host Test Fixture Kit is designed for use with Keysight oscilloscopes to facilitate compliance testing of high-speed USB host ports. The kit includes a test fixture that enables accurate probing of USB signals, ensuring reliable and repeatable measurements for USB 2.0 high-speed host compliance testing. It is compatible with Keysight's Infiniium oscilloscopes and supports the USB-IF compliance test procedures. The E2667B provides the necessary physical interface and signal access required for thorough validation of USB host implementations, helping engineers verify signal integrity and protocol compliance according to industry standards.
