The Examiner application uses an enabled USB Explorer 280 system to emulate a host when
testing a device (or hub upstream port), or to emulate a device when testing a host (or hub
downstream port). For Chapter 10 testing, two enabled EX280s are used to emulate US and DS
ports of the hub under test (HUT). See Section 3, Hardware Setup and Configurations for
details.
Optionally, an Explorer 280 analyzer (EX280A) can be placed in-line between the EX280 running
Examiner and the port under test (PUT), in order to capture the activity and store traces
between Examiner and the PUT for later review.
