Introduction Welcom e
Welcome
The High Speed Serial (HSS) plug-in is a waveform creation application that takes an input pattern and
creates pre-distorted waveforms to test a device's conformance to standards.
The High Speed Serial plug-in is designed to integrate and operate seamlessly as an enhancement to
the following products:
SourceXpress waveform creation software
AWG70000 series arbitrary waveform generators
AWG5200 series arbitrary waveform generators
Once installed, the plug-in becomes available as another waveform plug-in application.
This illu
plug-in is identical whether it is used from SourceXpress or installed on a generator.
stration shows the High Speed Serial plug-in viewed from the SourceXpress application. The
Key features
Jitter Generation: Up to four different sinusoidal jitters with different amplitudes, frequencies and
phases can be added to a base pattern. Three independent band-limited random jitters can also
be added to the base pattern.
Inter Symbol Interference (ISI) Creation: Directly create ISI.
High Speed Serial Printable Help Document 1
Introduction Key features
S-Parameters: Scattering parameters can be directly convolved with the base pattern to recreate the
channel charact eristics. S-Parameters can be entered directly from an S-Parameter file captured from
a Tektronix sa
de-embedded from the circuit. Cascading S-Parameters allows you to cascade up to six Touchstone
files of the same format to emulate a cascaded channel.
Noise: Vertical noise can be added at both near and far ends of the channel.
mpling oscilloscope. By applying an inverse filter, the effects of the channel can be
Idle State:
burst. You can directly create this idle state without using additional power dividers. Noise can also be
added to these idle state waveforms.
Batch Processing: When more than one pattern needs to be s ynthesized, you can use batch processing
to create multiple waveforms with a combination of one random and maximum of 2 sinusoidal jitter
Sequencing: You can add compiled waveforms directly to existing sequences or create sequences
using the Batch Compile feature.
Marker outputs: Marker outputs can be configured to be the same as the input base pattern or to
generate clocks at a user-defined frequency. You can also set the marker output to all high, all low,
or trigger.
Pre/de-emphasis and Preshoot: Provides flexibility to program the Pre/De-emphasis and Preshoot
sample by sample. The preview feature facilitates you to arrive at the most optimized Pre/de-emphasis
for a particular channel quickly.
Scrambling and 8b10b encoding: The input data pattern can be scrambled by defining a polynomial.
You can also encode using the 8b10b encoding option. 8b10b encoding works with D and K symbol
pattern only.
NRZ, NRZ-I, PAM, and PWM: Allows you to define the pattern duty cycle using the Pulse Width
Modulation (PWM), and alternatively encode the bit stream to 4- 8- 16-PAM, NRZ, or NRZ-I.
Gray Coding: Enables you to select a file to provide Binary to Gray code conversion for the PAM
signaling scheme.
Standards like SATA call for OOB signaling which requires an idle state followed by a
