Test Description
The Test Description panel allows the user to
designated the Test Type (either Receiver Test or
Transmitter Test) and number of channels to be
tested (from 1 to the maximum number supported by
the system hardware). The channels tested will always
start with Channel 1 (e.g., if two channels are selected on a system that supports four
channels, the channels tested will be Channel 1 and Channel 2).
Device Description
The Device Description panel allows the user to specify
the protocol to be used (options are SATA, SAS, PCIe,
USB 3.0, Custom or None) and the direction (DUT is
Device or DUT is Host).
Building a Test Script Block-by-Block
Test scripts are built block-by-block through the
addition of new blocks. At the bottom of the test
script will appear the options to add a
Reset/Initialize block or to add a Test Case block.
The Reset/Initialize block is normally the first block added immediately after the Test
Script Data Panel, since typically a device first needs to be initialized and placed into the
loopback mode prior to any Test Case. However, the Reset/Initialize block can also be
used at later times during a test script, if the user desires to reset the device prior to the
next Test Case or to terminate the testing with a final reset to place the device into a
known condition.
The Reset/Initialize block may be omitted entirely if the device is going to be manually
placed into a loopback mode prior to running the test script.
Reset/ Initialize Block
The Reset/Initialize Block contains the Device Reset tab, which contains three panels,
Setup, Initialization and Automation.
Setup
The Setup panel allows the user to specify (or change)
the data rate, the use of SSC and the Clock Out
settings. Depending on the protocol selected, the
options will include all supported data rates.
