AUTO CALIBRATION FEATURE ON BUSXPERT SOFTWARE
connecting a SerialTek PCI Express interposer
to an analyzer is a fairly straightforward procedure, but what
isn't as straightforward is getting the analyzer to link up cleanly
to a system under test (SUT). The manual calibration procedure used
by many customers to get a SUT properly working on SerialTek's
analyzers is changing the jumper settings (on interposers) by hand
or boosting or weakening signals in software until good settings
are found. This trial and error way is both tedious and
time-consuming; but it is a required task in order to put the
analyzer into a clean, error free link state with the SUT.
With the new Auto Calibrate feature on BusXpert analyzers, users
are liberated from having to change calibration settings by hand.
The software tests all possible setting combinations and
automatically select the right one to connect to the SUT. Now
going from connecting all the necessary components to doing actual
doing analysis and testing is quicker and more accurate.
The Auto Calibrate feature will be available in the next version of
the BusXpert software expected to release in early July 2016.

PCI Express, Link Training and Status State Machine (LTSSM) states
refer to the various states and sub-states that a PCI Express
system can be in. There are many different states in the PCIe
standard, ranging from Detection, Polling, Configuration, and
Recovery to just to name a few. There are also various actions that
allow the device to change to a different state. A LTSSM view is
the most intuitive way to visualize this complex set of
Many long time users of the BusXpert know that the software has
many views, providing users with multiple ways to visualize trace
data in a clear and organized fashion. The LTSSM view has been
added to provide a graphical way to see LTSSM states and sub-states
and their transitions. The BusXpert software shows where in the
LTSSM diagram the device currently is, and all the different changed
states in real time. Along with visualizing the PCIe statuses,
triggers can now be done on the various actions that move the
device to a different state. This LTSSM view is an invaluable tool
for testing PCIe devices that take advantage of power management.
The question of what state the device is in can now be demystified
with a visual diagram. The LTSSM view will appear in the next major
release of the BusXpert Software coming in July of this year.
2 OF BUSXPERT PRO ANALYZER RELEASED
PCIe/NVMe analyzer has been recently refreshed. Meet the
all new BusXpert PRO PCIe/NVMe analyzer (version 2), offering a
step up from the previous version. As one of our more popular
analyzer models, the PRO has one of the biggest buffers on the
market at 72GBs. One of the most requested features of the new PRO
is the ability to use SerialTek unique
adapters at Gen 3 data rates. The older BusXpert PRO could only
support SerialTek adapters at Gen 2 data rates.
you have one of the older PROs and wish to upgrade or trade-up to
take advantage of the newer capabilities of the version 2 PRO,
please contact us for more information. We
have very attractive financial programs in place to assist
AT GRL SEMINAR
April 20th, SerialTek participated in a Granite River Labs' (GRL) led
seminar located at GRL's headquarters in Santa Clara. David
Nuttall, a hardware engineering manager at SerialTek, delivered a
PCIe/NVMe focused presentation titled "Validation
and Testing Challenges of NVMe Subsystems". In this
presentation, David not only goes over the advantages of NVMe over
SAS/SATA, but also brings up various challenges when working with
NVMe technology and how overcome them. For those of you who are
interested in the presentation but were not available during the
seminar, you can find the presentation here.

SerialTek will be
attending the Flash Memory Summit on August 16th to the 18th at the Santa
Clara Convention Center. The Flash Memory Summit is one of the biggest
event in the year for storage. Be sure to join us as we showcase a
new BusXpert PRO PCIe/NVMe analyzer, dual-port U.2 adapters, and a
powerful LTSSM View in BusXpert software. You can visit the Flash

attended the 2016 SAS Plugfest
hosted by UNH-IOL. This event took place from May 23 to May 26 in Durham,
NH. Since this event was focused on the SAS protocol, SerialTek brought
out its SAS analyzers
and logic adapters
to the event to support participant companies at the plugfest. SAS stands for
Serial Attached SCSI, and is a common protocol used by storage
systems and devices in enterprise class servers.
At the event, SerialTek showcased newer decodes for SAS. Logic adapters
were also shown operating with SerialTek analyzers
for SAS traffic, and support for SAS power management was also

SOLVING JAVA ERRORS
software relies on Java to power the user interface. If Java cannot be
found, the BusXpert software cannot run correctly. Sometimes, an install
of the BusXpert software may not work properly because Java is either not
found or not installed in the correct directory. The default install
directory for 32-bit JRE/JDK is C:\Program Files (x86)\Java\. Here are
some steps to determine if the environment variables are set up correctly
- Go to
"Control Panel", then click on "System" and then
"Advanced System Settings". Finally, click the
"Environment Variables" button in the bottom right.
- Under system
variables, look for "Path" (scroll down the alphabetical
"System variables" list).
- Click on
"Edit" for the Java environment variable(s).
- Copy and
paste the "Path" environment variable into a text editor.
- Click the
"Path" row to highlight it and click "Edit".
- Copy and
paste the text in the edit box into a text editor. Using a text
editor, search for the string "Java".
If "Java" is
found, default settings are being used to run BusXpert. If more than one
instance is found, order becomes important. You will want to make sure
that your answer from part 1.c , e.g. C:\Program Files
(x86)\Java\jre7\bin is listed first.
To manually modify/repair the Java path environment
- If the
"JRE7/bin" path is not found, paste the Java path found in
- In the edit
box scroll past all the system root paths.
- Then, insert
the Java path foudn in Part 1.c immediately after the semicolon
after the last system root path.
- Remember to
add a semicolon (";") immediately after the new Java path
(before the next path in the last), as "C:\Program Files
- Save the
modified Path variable and reboot the computer so the path takes
After doing these steps,
try running the BusXpert software again and see if the Java error goes
