6. A step-by step guide explains the following individual setup steps. When you have finished all steps of the step-by-step guide, the compliance test runs automatically.

4.2 Connecting Probes to the DUT

In order to get precise test results, it is important to consider the experimental setup.
Special care should be taken when connecting the probes to the DUT as the connec­tion may affect the resulting measurement bandwidth. Especially when doing measure­ments in the HS400 Mode with data rates of up to 400 MBit/s you should make sure that the measurement signal bandwidth of 1 GHz is available. Smaller measurement bandwidth may lead to incorrect results.
There are different solutions you can use for connecting the probes to the DUT such as flexible sockets, special interposers or dedicated measurement points. It is important to consider during the design of your DUT.
