Using Online Help

Online help has many advantages over a printed manual because of advanced
search capabilities. You can select Help> Topics on the right side of the
application menu bar to display the Help file.

The main (opening) Help screen shows three tabs across the top, each of which
offers a unique mode of assistance:

 Contents (TOC) tab - organizes the help into book-like sections. Select a

book icon to open a section; select any of the topics listed under the book.

 Index tab - enables you to scroll a list of alphabetical keywords. Select the

topic of interest to display the corresponding help page.

 Find tab - allows a text-based search. Follow these steps:

1. Type the word or phrase you want to find in the search box.

2. If the word or phrase is not found, try the Index tab.

3. Select some matching words in the next box to narrow your search.

4. Choose a topic in the lower box, and then select the Display button.

Note: The Find tab function does not include words found in graphics

 To print a topic, select the Print button from the help topics menu bar.

Select the Back button to return to the previous help window. Sometimes you can
jump from one topic to another through a hyperlink. If the Back button is grayed
out, or a jump is not available, choose the Help Topics button to return to the
originating help folder.

Getting Started

Getting Started

About the Option SST Analysis Modules

The Option SST Analysis Modules consist of two modules−Serial ATA and
SAS− that are plug-in software modules to the Tektronix RT-EYE Serial
Compliance and Analysis application that runs on some Tektronix Windows­based oscilloscopes.

You can use these modules to test storage devices as per the Serial Advanced
Technology Attachment or SATA (Gen I and Gen II) and Serial Attached SCSI
(SAS) standards. After the measurements are taken, the results are displayed to
show whether the device has passed or failed the test.

Compatibility

Other features include:

 Performs Eye, Timing, and Amplitude measurements, and OOB tests

according to industry standard methods

 Selects and configures multiple measurements using differential or single-

ended probe inputs for receiver and transmitter devices

 Creates, formats, and generates reports

The measurements that are available in the Serial ATA module are: Eye, Bit
Rate, Differential Skew, Rise and Fall Time, Unit Interval, Differential Voltage,
AC CM Voltage, COMINIT, COMWAKE, and COMRESET.

The measurements that are available in the SAS module are: Eye, Bit Rate, Rise
and Fall Time, Differential Skew, COMINIT, COMWAKE, and COMRESET.

For information on oscilloscope compatibility, refer to the Optional Applications
Software on Windows-Based Oscilloscopes Installation Manual, Tektronix part
number 071-1888-XX. The manual is available as a PDF file.

Requirements and Restrictions

 The RT-EYE Serial Compliance and Analysis application must be installed

for the Option SST Test Modules to run.

 The Sun Java Run-Time Environment (JRE) V1.4.0 and The Mathworks

MATLAB Run-Time Server are components of the Option SST test
modules. When you install the application, the InstallShield Wizard
automatically installs the proper software components.

MATLAB Server. The MATLAB server is dedicated to the RT-Eye application
and cannot be used for other purposes. Do not close the MATLAB Server icon in
the oscilloscope task bar because this will disrupt the operation of the Option
SST Test Modules. The application will close the MATLAB sever when you exit
the application.

File Menu

You can use the File menus to save and recall different application setups and
recently accessed files.

Note: The File> Save function saves application settings in an .ini file and the
settings of the oscilloscope application in a .set file with a matching name.

If an oscilloscope .set file with a matching name is found when you recall an
application setup file, then the oscilloscope settings are also recalled. If the .set
file is missing or cannot be opened by the oscilloscope, then the application
recalls the application settings and displays a message that the Recall of the .set
file failed.

Do not edit a setup file or recall a file not generated by the application.

If neither option is selected then, filter operation will start from an arbitrary
sample point and filtered data can be affected by the filter transient response. The
filter transient response depends on the initial jitter on the data.

24

If neither option is selected then, filter operation will start from an arbitrary
sample point and filtered data can be affected by the filter transient response. The
filter transient response depends on the initial jitter on the data.

When you select option three, the configured transient time should be greater
than three times the number of clock transitions. The number of transitions is 550
otherwise the application displays the error message indicating that enough UI
edges are not available to calculate eye height. The eye generation fails to
complete successfully. For example, in the TDS7704B oscilloscope for align.pat
the recommended horizontal scale is > 40 ns for sufficient clock transitions.

When you select option four, ensure that the acquired waveform has more than
550 clock transitions otherwise the application displays the error message

Option SST Serial ATA and Serial Attached SCSI Analysis Module

Operating Basics

indicating that enough UI edges are not available to calculate eye height. The eye
generation fails to complete successfully.

The SAS Eye measurement requires at least three data packets that has ≥ 550
clock transitions in the acquired data to calculate clock recovery correctly. If the
acquired pattern has insufficient clock transitions (550) then you need to acquire
more packets for sufficient clock transitions.

Using a Limit File

Each module (SATA and SAS) provides a limit file that includes the
measurements and their range of permitted values. The module uses the limit file
to determine the Pass or Fail status for the measurements.

To change the limit file that your module uses, select Measurements> Limits.
Browse to the directory and select a limit file to use with a .lim file name
extension.

For the Serial ATA module, the files SerialATA-6k.lim and SerialATA-7k.lim
are available for the TDS6000 and TDS7000 series of supported oscilloscopes.
For the SAS module, the files SAS-6k.lim and SAS-7k.lim are available for the
TDS6000 and TDS7000 series of supported oscilloscopes.

Note: You must not edit the limits file. If you edit the limit file, the measurements
will not execute.

You use the Control Panel to start or stop the sequence of processes for the
application and oscilloscope to acquire information from a waveform. The
application then determines if the algorithm for the selected measurement can be
applied to the waveform information. Sequencing is the steps to acquire
waveform information, determine if the information is usable for the
measurement, take the measurement, and display the results.

Editing a Serial ATA Mask File

The mask files for Serial ATA are located in C:\Program
Files\TekApplications\tdsRT-Eye\lib\RTEye. The mask file name indicates the
technology, test point, number of unit intervals, and the device usage model. For
example, for the file SataTX250G1i.msk, "Sata" indicates the technology, "TX"
indicates transmitter, "250" indicates the number of unit intervals, and

Set up the DUT

Methods to Test a DUT

You can set up the Device Under Test (DUT) and test it in two ways: using the
Arbitrary Waveform Generator (AWG), or the BIST FIS/User-defined method.

In the AWG method, the AWG provides an external stimulus to the DUT. The
DUT, in turn, responds with the OOB signals and Align Patterns on which the
Serial ATA and SAS test modules can make measurements.

In the BIST FIS/User method, you can program the DUT to emit or transmit
various patterns on which the Serial ATA and SAS test modules can make
measurements.

The following table lists the test fixture connectors and the signals that are
connected to the test fixture:
