Discussion:

Reference [1] specifies the Transmitted Signal conformance limits for SATA products. The maximum

differential amplitude shall be measured at the TX Compliance point into a Lab Load. A Gen3 MFTP shall

be used for this compliance measurement. The MFTP will contain emphasis due to its run length, if the

transmitter supports this signal conditioning, and allows for simple edge triggering for the signal capture.

The maximum amplitude is defined as the peak to peak value of the average of 500 waveforms

measured over a time span of 4 Gen3 UI, using the HBWS. Reference [2] provides the definition of this

term for the purposes of SATA testing. Reference [3] defines the measurement requirements for this test.

This test requirement is only applicable to products running at 6Gb/s.
