TX+ signal that will be delivered to the RX+ input on the products. The remaining 81134A data outputs,

Channel 1 negative (-) and Channel 2 positive (+) are mixed together and delivered to the RX- input on the

products through the Crescent Heart Software TF-SATA-NE/ZP or TF-eSATA-NE/ZP test adapter or

equivalent.

The OOB Tests are designed to be run concurrently for simplicity. Since the initiation of a COMRESET

from a products or pattern generator will force a hard reset in a products, the following OOB tests can all be

performed using an Agilent 81134A 3.35Gbps Programmable Pulse/Pattern Generator to generate the

nominal OOB COMRESET and COMWAKE bursts, as well as to stress the minimum and maximum

voltage threshold conditions for OOB Signal Detections. The Agilent Infiniium oscilloscope, which is

running the N5411B SATA test software, will control the pattern generator stimulus as well as the

oscilloscope acquisition and processing parameters, providing fully automated control and repeatability of

the OOB test sequence in successive fashion. A COMRESET is issued from the generator prior to running

each test to ensure products reset, but in some cases, it may still be necessary to remove power from the

products under test temporarily to allow the products to exit from a BIST controlled mode and return to

normal operation.

Example OOB Setup for a SATA Device:

The N5411B software includes a calibration routine to verify the amplitudes for the OOB bursts used to test

OOB minimum threshold detection amplitude at 40mV and 210mV for Gen1 products and 60mV and

210mV for Gen2 or Gen3 products.
