80SJNB - Jitter, NOise, BER and Serial Data Link Analysis Software
1 Introduction
The purpose of this new versions, V4.1.31.0, of 80SJNB, Jitter, Noise,
BER and Serial Data Link Analysis software is to enhance the
capabilities of the DSA8300 Digital Serial Analyzer by providing Jitter,
Noise, and BER analysis for PAM4 signaling.
80SJNB Essential provides Jitter, Noise and BER analysis for NRZ and PAM4 signals.
The Advanced option adds capabilities for de-embedding of text fixtures,
channel emulation based on TDR/TDT and S-parameter models, and design and load
CTLE filters, FFE, DFE equalizer support, rise and fall measurements,
and a large set of global PAM4 signal characterization measurements.
The PAM4 option builds on the Advanced option, and supports comprehensive analysis
on PAM4 signals.
PAM4 support is incompatible with Spread Spectrum Clocking (SSC).
Demo license:
For demonstration purposes the full Advanced and PAM4 version of 80SJNB will
start and run on a mainframe, without any key, for a total of ten
times. Please contact Tektronix to purchase a license.
New license:
80SJNB can be purchased with either the option key for Essential,
the option key for Advanced features, or the option key for PAM4 support.
This document addresses operations related to the specifics of
working with 80SJNB on the DSA8300.
These Release Notes can be accessed via a short cut from:
Windows Start-> All Programs->Tektronix Applications->80SJNB.

(SSC), this application requires that the DSA8300 oscilloscope be
equipped with a Tektronix (82A04 or 82A04B) Phase Reference module. Contact
Tektronix about purchasing the module for your oscilloscope.
2.2 Installing the Product Software
Installing the Product Software requires administrative privileges
since the installation routines need to modify settings that apply to
all instrument users. The factory installation of the Windows 7
operating system is configured to automatically log into the
"Administrator" account (no password is needed) during the boot process. If
this behavior has not been modified, then you are ready to install the
Product Software. Otherwise, you will need to manually log into the
instrument as an administrator.
If installation from a LAN is desirable, the contents of the Product
Software CD (or the downloaded Web installer) may be copied to a
file server. The autorun.exe program must be executed manually to
proceed with installation over the network. Although the Windows 7
operating system supports automated application deployment features such
as "Systems Management Server", automated deployment of the Product
Software has not been tested with this release. We do not anticipate
any unique automated deployment issues with this version of the
Product Software.
The latest version of 80SJNB software, 4.1.31.0 can be found only on the Tektronix
web site www.tektronix.com.
If CD for installation is available, follow this directions:
1. Insert the Product Application Software CD and run the
autorun.exe.
2. Select "80SJNB Jitter, Noise, and BER Analyzer".
3. When installation is complete, consider installing the "80SJARB -
Arbitrary Jitter Analyzer" and the "Serial Data Link Analysis",
or Finish with an instrument reboot. The reboot is required before
either application will run.

provided to NRZ signaling to PAM4 signaling. The new version of software provides:
3.1.Comprehensive jitter, noise and BER analysis
The new release expanded the jitter, noise and BER analysis to all 3 eyes generated
by PAM4 signaling. That includes Random Jitter, RJ, Bounded Uncorrelated Jitter, BUJ,
and Total Jitter at specified target BER, [email protected], Random Noise, RN, Bounded Uncorrelated Noise,
BUN, and Total Noise at specified target BER, [email protected] for each individual eye.
3.2 Transmitter centric measurements
Transmitter symbol levels, transmitter linearity, level thickness, level time deviations
measurements are supported.
3.3 Receiver centric eye measurements
Vertical eye closure, eye center deviation, and eye width for each of the 3 stacked eyes.
3.4 Receiver optimization
Analysis of optimal receiver positioning computes the optimal decision threshold and
sampling phase for each individual eye for maximum eye width and height.
3.5 Support for transmitter equalization in form of Continous Time Linear Equalization
(CTLE) and receiver equalization schemes, Feed Forward Equalization (FFE), Decision
Feedback Equalization (DFE).
3.6 Channel emulation with the de-embedding and embedding S-parameter modeling.
3.7 All features, new and legacy, are supported by programmatic interface, PI, commands.
3.8 All test results can be exported to a csv file. Screen shots for measurements on each
eye can be saved in designated files.
3.9 Perform full rise/fall time measurements on all PAM4 transitons with comprehensive

3.10 Support for variable number of samples per unit interval to be able to support long
pattern lengths, equivalent to the length of PRBS16.
3.11 Support for IEEE and OIF-CET requirements for eye measurements.
4 Changes Included in Prior Release Version 4.0.8.0
4.1 Perform Mask Testing
Mask Testing are performed on statistical eye products of jitter and noise
decomposition process and analysis. Specifically, Mask Testing is performed on
PDF Eyes (Probability Distribution Function Eyes) and on the BER Contours
(Bit Error Ratio Contours) models.
Computing these models at multiple points in the serial data link further expands
DUT analysis, Transmitter equalization, de-embedding of fixture and probes,
multiple models of channels and multiple receiver equalization models allow for
extensive exploratory Mask Testing.
4.1.1 A full set of Standards’ generated masks are supported, both for optical and electrical links.
4.1.2 A published standard mask file format has been generated and documented in the
on-line help, so users can modify or even generate their own mask requirements.
4.1.3 There two targets for testing: SP Receiver PDF Eye and BER Contours. Configuring
the data link allows for the emulation of the serial data links.
4.1.4 SP Receiver PDF Eye testing supports the following use cases: Find Mask Margins,
Measure Hit Ratio, and DUT Pass/Fail Test.
4.1.5 BER Contour testing supports the following use cases: Find Mask Margin,
Measure BER Limit, and DUT Pass/Fail Test
4.1.6 Mask Testing allows for the horizontal optimization of mask positioning for
maximum mask margins.
4.1.7 Full programmatic interface is in support of all Mask Testing features.
4.1.8 A library of standard masks is available when loading the 80SJNB software.
4.2 Selecting a Stop on Condition
A Stop on Condition selection allows controlling the amount of data to be
acquired and processed before stopping. The Free Run mode has to be selected
from the tool bar in order for the Stop on Condition to become active.
There are four options to control the stop condition:
1.Never. This is the default condition. The acquisition and processing of
data runs continuously until explicitly stopped by clicking on the Stop button.
2.Acquisition Cycles count instructs 80SJNB application to continue acquiring and
processing until the defined number of cycles have completed.
3.Uncorrelated Samples instructs 80SJNB application to continue acquiring and
processing data until the data required for uncorrelated jitter and noise
processing exceeds the specified count.
4.Total Population Limit instructs 80SJNB application to continue acquiring and
processing data until the total number of samples exceeds the specified number.
Included in this count is the total number of data correlated samples that
corresponds to 100 samples per pattern bit.
The actual number of acquired and processed samples is displayed in the Sample Count field,
and corresponds to the nearest integer number of acquisition and processing cycles.
The PI commands supporting this feature have been included in the on-line help.
7 Known Limitations
7.1 Running Applications Simultaneously
Attempting to run both IConnect software and 80SJNB at the same time
may cause problems and one or the other, or both applications will
not work properly. Having both applications active at the same time,
even if they are not collecting data, may cause improper operation
of either application. Each application will work properly when run
individually. Be sure to exit one application before starting the
other.
7.2 Install TekScope Application before 80SJNB
Always install TekScope application before installing 80SJNB. For
example: after a restore OS, install TekScope before installing the new
version of 80SJNB. Wrong information could be displayed if order is
reversed.
7.3 OMA/VMA Measurements for NRZ are PI only
The OMA/VMA measurements have not been added to the display, but there
are available from the programmatic interface; see Online Help for details.
7.4 PI Command for Symbol Rate
In order to set the Symbol Rate use the following PI command:
variable:value “DataRate”,”value”
7.5 Checking Version Number via Programmatic Interface (PI)
The following PI command will return the current version number of
80SJNB:
variable:value? "Version"
8 Examples
A set of example files are included that configure the serial link
(Advanced option) with an arbitrary FIR filter and include a channel
descriptor defined either in the time domain or in the frequency
domain.
The example files are installed in the following directory:
C:\Program Files\TekApplications\80SJNB\Examples
The examples include three Gaussian FIR filters, a generic
S-parameter file, S-parameters for an InfiniBand 5 m cable, time domain
waveforms for an HDMI cable, and finally TDR waveform pair for a 1 m SATA
cable.
The following is a list of folders containing the examples:
Examples
Channel Sparam
FIR Filters
HDMI cable TimeDomain
InfiniBand 5m_cable
SATA 1m_cable TimeDomain
9 Programming Samples
The 80SJNB Online Help contains three program samples:
* Configure and operate 80SJNB. Setup acquisition, run, and read
results. Identify and characterize error conditions.
* Measure Jitter in Presence of SSC. Configure acquisition and
accessories for characterizing SSC. Run and read results.
* Compensate for Signal Path Impairments with Equalization. It
illustrates how to emulate severe ISI by using a Channel emulator, then
use Equalizer for compensating for channel impairments, then
assess results by measuring data dependent jitter and vertical eye
opening.

3 Key Benefits of Installing 80SJARB
The 80SJARB Jitter Analysis of Arbitrary Data software enhances the
capabilities of the DSA8300 Tektronix sampling oscilloscopes. This
application provides basic jitter measurements for arbitrary data
signals, including:
* J2 - Total jitter for Bit Error Rate (BER) = 2.5E-03
* J9 - Total jitter for BER = 2.5E-10
* Tj - Total jitter for BER = 1.0E-12
* DJδδ – Deterministic jitter (Dual Dirac method)
* RJδδ – Random jitter (Dual Dirac method)
* Jitter bathtub curve graph (both measured and extrapolated data)
* Histogram of the acquired data
The accuracy and repeatability of all measurements improves as the
application acquires additional data. While the standards specify
that J2 and J9 measurements be taken on a minimum of 10,000 points,
the 80SJARB application acquires data beyond this minimum requirement
(in Free-run mode) and shows the number of points used for the
extrapolated measurement calculations.
Tektronix also offers two other jitter measurement applications for
the DSA8300 oscilloscope: 80SJNB (Jitter, Noise and BER Analysis
Essentials) and 80SJNB-01 (Jitter, Noise and BER Analysis Advanced).
Shown below is a comparison of Tektronix' sampling oscilloscope jitter
measurement applications:

datasheet from www.tek.com for up-to-date information.
Note: Scopes that have an 80SJNB or 80SJNB-01 licenses also can run the 80SJARB application.
4 Known Limitations
Only directly 80SJARB relevant ones are listed here:
4.1 Do Not Attempt to Run 80SJARB, 80SJNB or IConnect Simultaneously
Attempting to run any of these applications at the same time may
cause problems and the applications will not work properly. More than
one application active at a time, even if not collecting data may
cause improper operation. Each application will work properly when run
individually. Be sure to exit one application before starting
another.
80SJARB has a Hibernate mode, which allows for running 80SJNB while
80SJARB is active.
4.2 Interaction with Instrument Default Setup
An oscilloscope Default Setup will delete the 80SJARB state. Since at
this time 80SJARB does not have an equivalent functionality, it is
necessary to restart 80SJARB after an instrument Default Setup
action.
4.3 Analysis on Previously Acquired Data
80SJARB will analyze data that has been acquired and stored in a
histogram. This feature applies only to data acquired on a Main time
base. A known limitation is that if data has been acquired in a
waveform database and histogram on a Mag view, the analysis results will
not be correct.
4.4 Stop Applications before Exit
It has been noted that exiting the application while running in Free
Run mode and displaying both data plots the scope front panel could
remain locked. Stopping the application before exit will avoid this
issue. The following programmatic interface command will unlock the
scope front panel:
lock none

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 âApplyâ button in main
menu to update Tp filters and equalization results.
- To set custom bandwidth limit, click âApplyâ button in bandwidth filter design
menu to update the global bandwidth limit filter based on the bandwidth settings.
Clicking âOKâ 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.
6. Installation
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
