QPHY-SATA Test Configurations

Configurations include variable settings and limit sets as well, not just test selections. See the QPHY-SATA

Variables section for a description of each variable value and its default value. The limit sets are either Gen1i,

Gen2i or Gen3.

Demo of 1.5 Gb/s Device with SSC

This configuration uses waveforms stored on the oscilloscope in D:\Waveforms\SATA\Demo to demonstrate a

Gen1 device with SSC. The word "Demo" must be entered as Device Under Test in order to run this

demonstration. The limit set in use is Gen1i. All of the variables are set to their default settings except External

Attenuation is set to 0 (which is not relevant when running stored waveforms), SSC is enabled, TestMode is set to

Use Saved Data and Filenames point to 1.5Gb/s data files. The tests that are demonstrated are:

 PHY-01 – Unit Interval

 PHY-03 – SSC Frequency

 PHY-04 – SSC Deviation

 TSG-01 – Differential Output Voltage

 TSG-02 – Rise/Fall Times

 TSG-03 – Differential Skew

 TSG-09 – TJ at Connector, Edge-Ref fbaud/500 (1.5Gb/s)

 TSG-10 – DJ at Connector, Edge-Ref fbaud/500 (1.5Gb/s)

 OOB-01 – Signal Detection Threshold

 OOB-02 – UI During OOB (Bitrate)

 OOB-03 – COMINIT and COMWAKE Burst Length

 OOB-04 – COMINIT Gap Length

 OOB-05 – COMWAKE Gap Length

 OOB-06 – COMWAKE Gap Detection

 OOB-07 – COMINIT Gap Detection

Demo of 3.0 Gb/s Host without SSC

This configuration uses waveforms stored on the oscilloscope in D:\Waveforms\SATA\Demo to demonstrate a

Gen2 device without SSC. The word "Demo" must be entered as Device Under Test in order to run this demo.

The limit set in use is Gen2i. All of the variables are set to their default settings except Product Type is set to

Device, External Attenuation is set to 0, TestMode is set to Use Saved Data and Filenames point to 3.0Gb/s data

files. The tests that are demonstrated are:

 PHY-01 – Unit Interval

 PHY-02 – Frequency Long-Term Accuracy

 TSG-01 – Differential Output Voltage

 TSG-02 – Rise/Fall Times

 TSG-03 – Differential Skew

 TSG-04 – AC Common Mode Voltage

 TSG-05 – Rise/Fall Imbalance
