Exerciser Description

In Exerciser mode, the USB Explorer 350 emulates a USB or USB Power Delivery port or device for purposes of
characterizing another port or device, or the physical media. In this mode, the USB Explorer 350 essentially replaces
a system component. For example, it may be configured to emulate a USB host and then be connected to a USB
device, or it may emulate a USB Power Delivery consumer in order to test the corresponding provider or a Type-C
Electronically Marked cable plug.
In this mode, two USB Explorer 350 units are typically used: one to act as the Exerciser, and the other to act as
Analyzer, capturing traffic between the Exerciser and the device under test (DUT) for debug and characterization
purposes.

The USB Explorer 350 uses the Examiner application to execute compliance or verification tests against a USB host,
device, USB PD Downstream-Facing Port (DFP) Upstream-Facing Port (UFP), Dual-Role Port (DRP), Type-C
electronically marked cable, hub, etc.
Examiner's tests are based on USB-IF compliance testing documents. Pass/fail criteria as well as test methodologies

In Examiner mode, two USB Explorer 350 units are typically used; one to act as the Examiner unit and the other to
act as Analyzer, capturing per-test traffic between the Examiner and the device under test (DUT) for debug
