Abstract
A test system including a storage device and a protocol analyzer coupled to the storage device. The storage device can include a diagnostic data transmission unit configured to transmit diagnostic data related to an operation of the storage device, and a host interface unit including a first selector configured to receive idle characters and the diagnostic data, wherein the first selector selectively transmits the idle characters or the diagnostic data. The protocol analyzer can be configured to autonomously receive the idle characters or the diagnostic data via the host interface unit.
