Preface
This user guide describes the SerialXpress application. This application can emulate all forms of channel impairments
and can pre-compensate for losses in the overall test setup and cabling. It eliminates the need for expensive and
difficult-to-obtain cable emulators.

Inter-symbol interference (ISI) creation: SerialXpress allows you to create ISI by entering it directly or from an
S-parameter file captured from a Tektronix sampling oscilloscope or a Vector Network Analyzer. The S-parameter can
be direct
effects of the channel can be de-embedded from the system. The ISI within the S-parameter can be scaled upward or
downward, easily altering the characteristics of the channel.
Base pattern: SerialXpress is bundled with several sample patterns for various standards like SATA, Display Port, SAS,

idth expansion filter: The bandwidth of an arbitrary waveform generator can be expanded further by applying
Bandw
the bandwidth expansion filter which compensates for DAC roll-off. For example, when used with an AWG7122B with
option 06, the bandwidth expansion filter compensates for the DAC roll-off at higher frequencies, thereby extending the
idth up to 9.6 GHz. This helps in improving the rise time.

Batc
multiple waveforms with a combination of random and sinusoidal jitter and a maximum of four different frequencies.
Overview window: All jitter parameters can be switched on or switched off from the overview window.
Cascading S-Parameters: SerialXpress allows you to cascade up to six Touchstone files of the same format to emulate a
cascaded channel.
Sequencing: SerialXpress supports sequencing of several base pattern types. You can specify several base pattern files,
different types of jitter to each base pattern, and compile them simultaneously. These waveforms are automatically

transferred to the AWG sequencer at the end of compilation.
Presets: SerialXpress provides pre-created setup files for standards such as SATA, USB 3.0, DisplayPort, and HDMI.
Selecting a preset loads the appropriate setup into SerialXpress.

Application Examples
Enabling Predistortion Through Digital Filters for Bandwidth Enhancement
This example shows how the frequency response of the system can be enhanced by applying bandwidth enhancement
digital filters. Using these filters, the frequency response can be whitened (flattened). You can apply these filters when a
sharp rise time or fall time is required. The example shows how to use a bandwidth enhancement fi lter.
You will need the following equipment:
A Tektronix DPO oscilloscope (for example, DPO71604) with a bandwidth greater than 16 GHz and capable of measuring
rise and fall time of the order of 50 picoseconds.
A Tektronix Arbitrary Waveform Generator AWG7102 with Option 06 with SerialXpress installed and running on it.
An external hardware filter (from RLC Electronics, Inc., part number: F-30-10.0.R) with the following specifications:

Characterizing the Receiver Using Spread Spectrum Clocking
The example shows how to characterize your receiver using spread spectrum clocking (SSC) modulation with and without
setting the df/dt parameters.
When df/dt is set to 0, the period and frequency time trend waveform will be exactly the same as the shape selected
(Sine or Triangle) in the SSC group.
When df/dt parameters are set, there will be a deviation in the period and frequency time trend waveforms at the specified
location, df/dt, and duration.
