To perform the Signal Quality test on USB 2.0 hi-speed devices, Keysight recommends using the E2666B USB 2.0 hi-speed device 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 devices 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.
