3. Main Features on SDLA Visualizer v2.0.0 release
- Measurement path de-embed and simulation path embed with auto/manual bandwidth
- Full 4-Port S-parameter modeling support that takes into account the Tx and Rx
impedance models, along with all transmission line characteristics.
- Support HiZ probe and SMA and scope de-embed. Multiple test points allow
viewing loaded and unloaded waveforms at once.
- RLC and lossless transmission line models.
- Pre-/De-Emphasis add/removal in transmitter block.
- CTLE, FFE and DFE equalization modeling tools with support for serial standards
in receiver block.
- IBIS-AMI model support in receiver block that allows using equalization files
supplied by a chip vendor.
- A rich set of plotting tools include S-parameter plots, time domain plots,
Smith chart, and overlay tools. These plots are available starting with the
cascade block configuration stage to verify the input models (i.e. S-parameters).
- Observe the signals via 12 user-defined test points, including 4 that are
movable within the De-embed and Embed Blocks. Multiple test points can be
viewed simultaneously. Test points can show the signals that could not be
- Dual-input support where individual single-ended signals are considered for the
source as well as for each test point. You are able to see the differential,
common mode, or individual single-ended signals at once.
- Auto set DPOJET to perform eye diagram analysis on up to 4 test points and
Version 2.0.1 of SDLA Visualizer is a maintenance release following version 2.0.0
for defect fix and added the following capabilities:
- Increase the Tp FIR filter limit in SDLA Visualizer from 3900 to 12K. And provide
an option to still use 3900 as the limit. So the created Tp filters can be loaded
to 32-bit scopes where arbFlt function in scope Math system has the limit of 3900
on FIR filters.
- Add P7625 and P7633 HiZ probe support.
Version 2.1.0 of SDLA Visualizer is a feature release after version 2.0.1.
It introduces the following features:
- AMI extension to support chunking and AMI file auto condensing.
- S-parameter and test point scaling.
- TDT waveform support.
- 3-tap Tx equalizer support.
- S6p and S3p interposer support.
- Create arbFlt for sampling scopes.
- Pre-DFE and pre-AMI re-sampled waveform output.
- Re-sample unevenly spaced S parameters.
Version 2.2.0 of SDLA Visualizer is a feature release after version 2.1.0. And it is
the first version that runs on sampling scopes. It introduces the following features:
- SDLA visualizer runs on sampling scopes. This allows sampling scope to cascade
multiple blocks, use full S parameter to take into account of reflections, cross
talks. SDLA on sampling combined with JNB provides a complete solution for HSS
signal path simulation on sampling scopes.
- SDLA supports the USB3.1 gen2 and MIPI M-PHY Gear4 CTLE and DFE reference equalizers.
- Extract s4p data from s6p, s8p, s12p, s16p files. The s6p, s8p, s12p, s16p files
can be loaded to cascade blocks and select 4 port for SDLA simulation.
- Boost limiter. This allows manually adjust the deembed responses.
- Improve IBIS-AMI support.
Version 2.3.0 of SDLA Visualizer is a feature release.
- Adds support for the new DPO70000SX class instruments by allowing to read
return loss characteristics of specific ATI channels for more accurate signal path
modeling and de-embed filter design. Probe support on these instruments is also added.
- Improves equalizer clock recovery for signals with SSC.
- Supports CTLE definition for USB3.1 Gen2 ECN.

- OPTION LEVELS
There are not multiple option levels for SDLA Visualizer.
- FREE TRIALS
This application generally requires a software option key to operate. The
application offers free trials for evaluation. Once the free
trials are exhausted, a software option key may be purchased from
Tektronix to permanently enable the software on your oscilloscope.
- SOFTWARE COMPONENTS
SDLA is powered by MATLAB Software. MATLAB is a registered trademark of
MathWorks, Inc. Tektronix' limited rights to the deployment of MATLAB
are governed by a license agreement which can be found in the following
directory: C:\Program Files\MATLAB\MATLAB Compile Runtime\v80.
- SOFTWARE UPDATES: REQUIRED REBOOTS
When upgrading to a newer version of the software, reboots may be required
both when uninstalling the old version and when installing the new. Please
follow any reboot instructions provided by the InstallShield.
- SWITCHING BETWEEN APPLICATIONS
It is possible to switch between SDLA and some other applications while
retaining measurement setup and results. However, SDLA's operation must
be completed before switching.
5. Known Problems
- SDLA control window may go behind Tekscope application window. Use Alt-Tab
keys to switch between SDLA and other applications.
- SDLA Visualizer v2.2.0 supports all setup files created from SDLA Visualizer
v2.0.0 and up.
- If any configuration parameters have been changed, click “Apply” button in main
menu to update Tp filters and equalization results.
- To set custom bandwidth limit, click “Apply” button in bandwidth filter design
menu to update the global bandwidth limit filter based on the bandwidth settings.
Clicking “OK” button will only close the filter design menu and the global
bandwidth filter may not be updated.
- On real-time scopes, before run Analyze in SDLA, DPOJET should have been started
already. Try to click "Analyze" button in SDLA before DPOJET starts, an error
message could appear saying DPOJET cannot be started. Make sure DPOJET has started,
then clicking "Analyze" button in SDLA again will setup DPOJET to draw eye diagrams.
- On real-time scopes, when source is a math waveform that relies on another math
expression rather than a live source or reference waveform, (for example, source
is Math1 where MATH1 = arbFilt(MATH2) and MATH2 = CH1 - CH3), SDLA code will fail
to recognize that an acquisition must be triggered. Try to avoid math-on-math
expressions. For the above example, use MATH1 = arbFilt(CH1 - CH3).
- On real-time scopes, DFE equalizer block can only process limited number of
points. When Equalizer is in user mode, and waveforms are greater than 10M in
length, the Equalizer block will only process the first 10M of the record.
The number of samples being processed by AMI model may vary depending on samples
per bit setting. The user may still have eye diagrams of test points in SDLA on
the waveforms that are greater than what has been processed but the eye diagram
for the Equalizer will be limited to processed data.
- on real-time scopes, when waveforms are too large the Math waveforms for the test
points may not be able to turn on if the scope runs out of memory. If this occurs
then messages appear suggesting that record length be reduced.
- On real-time scopes, when scope record length is set to be too large before SDLA
Apply, the scope may reduce the record length without warning when SDLA Apply tries
to turn on Math waveforms for Tps, and SDLA will wait for new acquisition.
Re-run Apply in SDLA to let scope acquire new data and SDLA can get consistent
results when scope record length is changed.
- On sampling scopes, as the operating system is 32bit, it has limited virtual memory.
SDLA may pop up message if it runs out of memory on large data set.
- On very rare occasion when starting SDLA, it reports that it cannot connect to
TekVISA. In this case restarting Windows will fix the problem.
By default, the SDLA application resides on the hard drive of your oscilloscope.
If the application is not installed on the hard drive or an update is desired,
it can be downloaded from the Tektronix website at http://www.tektronix.com.
Click on "Downloads, Manuals & Documentation" under "Support" and use "SDLA" in
the 'Search by keyword' control. Run the downloaded executable on the instrument.
- Follow the instructions given by the InstallShield Wizard.
- If this is an update to an existing install, the old version will be uninstalled
and you will need to restart the installation following completion of this task.
- When the installation is complete, the InstallShield Wizard asks if you want to
restart the oscilloscope. Click Yes.
- Enter the authorized Option Installation Key to enable the application.
The key is specific to the serialized oscilloscope and options for which it was
purchased. To enter the key number, follow these steps:
a. If the oscilloscope is powered on in the toolbar mode (default), select the
Menu button (upper right corner of the display) to put the oscilloscope into
menu-bar mode. In menu-bar mode, you should see a Windows PC-style
menu across the top of the display.
b. Go to the Utilities menu in the menu bar and select Option Installation.
c. Follow the on-screen instructions to enter the alphanumeric key number exactly
as it is printed on the rear-panel label.
The SDLA Visualizer application is now ready for use. Start the application through
oscilloscope menu selections under Analyze>Serial Data Link Analysis
