USB NRZI Line Oscillation Type 2 Test Failure Information

Test Group 3102

Device USB

This group is for Universal Serial Bus (USB). USB is a specification for the cables, connectors and protocols that provide convenient and flexible serial communication with connected devices at a variety of speeds. It is typically used to connect external peripheral devices ranging from a mouse to a back-up storage solution.

This group is only available if Eurosoft USB hardware is detected when the program initialises. It will not be available if there are no suitable USB devices connected to the USB ports.

Each device identified by this group corresponds to a Eurosoft USB Test Device or Eurosoft Program Device. It is not however this device which is tested, but the connectivity to it, comprising of controllers, traces, cabling and port.

Note: This test group requires enhanced Eurosoft USB Test or Program Devices, earlier Eurosoft USB Test Devices are not recognised in the UEFI product. The required plug type can be recognised by the presence of a file system partition.

Note: Devices should not be removed or inserted while diagnostics are running.

Test Number 405

Test Name NRZI Line Oscillation Type 2

NRZI Line Oscillation Type 2 Test. Hi-speed data transfers self-clock using transitions contained within the data transmitted. The encoding method is called non-return-to-zero-inverted (NRZI) encoding. This test uses a data pattern to set up a square wave oscillation within the data encoding. This tests for susceptibility to capacitive, inductive or conductive crosstalk. Each test type exploits a different frequency of oscillation.

Estimated Test Time 1m to 3m

ERRORCODES & TROUBLESHOOTING

The test cannot be executed because something is not supported. CODE="0x00/3FF"
TROUBLESHOOTING0: Ensure the proper Test Device is inserted to the USB port. Try re-plugging the device. Some BIOS require for Test Devices to be inserted prior to booting the diagnostics while power is off.

The specific test is unavailable. CODE="0x01/3FF"
TROUBLESHOOTING0: Ensure the proper Test Device is inserted to the USB port. Try re-plugging the device. Some BIOS require for Test Devices to be inserted prior to booting the diagnostics while power is off.

A read error occurred. CODE="0x02/3FF"
TROUBLESHOOTING1: An error occurred while reading the Test Device. There may be a hardware fault. You can try re-plugging the device. Some BIOS require for Test Devices to be inserted prior to booting the diagnostics while power is off. "

The USB test failed. CODE="0x03/3FF"

TROUBLESHOOTING2: The port appears to be faulty. You can try re-plugging the Test Device. Some BIOS require for Test Devices to be inserted prior to booting the diagnostics while power is off.
