PCI Express 3.0 Protocol Viewer Software
for Ininiium 90000 Oscilloscopes
Data Sheet
Simplify the validation of your PCI Express®
3.0 with the irst full capability protocol
viewer built into a digital oscilloscope.
Introduction
Keysight Technologies, Inc. N8816A Infiniium protocol viewer software for PCI
Express 3.0 enhances the industry’s first totally integrated oscilloscope-based
protocol analyzer technology providing time-correlated views of physical layer
and data link layer protocol. You get packet-level decode for PCI Express®
signals built into a real-time oscilloscope. This software provides you with
a fast, easy way to isolate signal integrity problems from logic-level coding
errors on bidirectional serial data streams. This capability allows you to test,
debug and characterize your designs to the logic and link layer. The N8816A
Infiniium protocol analyzer software has decode options for PCI Express Gen1
and Gen2 and Gen3 decode.
N8816A – Infiniium protocol viewer
PCIe™ Gen1, Gen2 and Gen3
E2688A SDA (prerequisite)
The N8816A Infiniium protocol viewer software is compatible
with Keysight 90000 Series Infiniium oscilloscopes.
Features
Comprehensive Decode Capability
The N8816A Infiniium protocol viewer software offers
several features to simplify the validation of your
PCI Express designs:
With the N8816A Infiniium PCI Express 3.0 protocol
analyzer software, you can use the same oscilloscope you
use for everyday debugging and signal quality testing to
perform protocol-level testing. The software automatically
decodes symbols, packets and ordered sets and provides
informative results. It includes decode of reserved bit
settings during training sequences and speed negotiation,
greatly simplifying debugging of link training failures.
– Setup wizard for quick setup, configuration and test
– Packet-level decode of ordered sets as well as link and
logical physical layers
– Serial data analysis with 128/130 bit streams (Gen3)
Some of the difficulties in validating PCI Express communication links are determining if link failures or instability
is due to electrical problems or logic-level problems. The
N8816A Infiniium PCI Express 3.0 protocol analyzer
software allows you to analyze the root cause of these
issues with a single piece of test equipment.
– Serial data analysis with 8B/10B symbols (Gen1, Gen2)
– Decode of scrambled and unscrambled symbols
– Bi-directional symbol and packet level decode
– Simultaneous display of packet/ symbol lists and
waveform overlay
– Capability to save symbol and packet data lists to .csv
and .txt files
– Packet decode details tab provides detailed information
on packets
– Channel information
– Listing index
– Link ordered set type
– Control symbols
– Reserved-bit settings
– Data payload popup
– CRC
– Packet length
– Payload display shows data payload
– Unique packet-waveform correlation marker “blue line”
makes it easy to scroll through waveforms to view
synchronized packet and symbol lists
– Comprehensive serial search capabilities
– Trigger and stop on search
– Primitive, control symbol and packet search capability

Easy Measurement Setup
The N8816A Infiniium PCI Express 3.0 protocol analyzer
software uses the Serial Data Wizard to simplify setup of
the clock recovery algorithm used to decode the various
speeds of serial traffic that it supports. The wizard guides
you quickly through the steps required to set up and
perform symbol and packet-level decode.
Figure 2. Next, the setup wizard asks you to enter the nominal
data rate.
If you use a PLL based clock recovery selection, setting
a higher loop bandwidth (ex: 40 Mhz) allows the clock
recovery software to sync with the serial data quickly and
decode more of the captured data.
Figure 1. To set up the decode, the wizard asks you to identify the
signal source and select the clock recovery algorithm (constant
frequency shown. 1st and 2nd order PLLs can also be selected).

Synchronized Analog and Digital
Display
In conjunction with the decode list, using the multi-grid
waveform display you can simultaneously display analog
bi-directional waveforms with corresponding decode
listings.
The N8816A Infiniium PCI Express 3.0 protocol analyzer
software provides the ability to perform 128/130 bit and
8b/10b based packet decoding via a patented (patent
pending) technique to capture and display serial data
synchronized with the analog view of traffic of a serial
data stream. Decode is displayed directly on the analog
waveform as well as in the decode list with associated
time and index displays.
Figure 4. Bi-directional waveform and packet list are displayed
simultaneously
The unique packet-waveform correlation marker “blue
line” (patent pending) allows for convenient and intuitive
correlation of analog and digital domains. You can easily
scroll to analog anomalies that are visually distinct, making
navigating and checking for errors easy, even for industryleading record depths.

the PCI Express signal

Comprehensive Search Capabilities
The expandable decode list provides an extendable
indexed view of packet decode for users who are more
accustomed to logic analyzer “vertical style” packet
decode traffic listings. The list includes color-coded packet
types for easier visual searching of traffic patterns as well
as a blue highlight that shows the packet that corresponds
to the “blue line” in the waveform view. The side bar also
shows how much of the waveform display is on the screen
by providing a gray background on the index field, as
shown in Figure 6.
The N8816A Infiniium PCI Express 3.0 protocol analyzer
software includes a powerful serial search tool which
allows you to search for a pattern that is a primitive,
control symbol or packet, depending on the version of the
PCI Express standard that is selected.

Figure 6. Expandable Decode List with correlation marker
(line index 14).
The search capability also includes a comprehensive
packet search and trigger capability that allows you to
specify search conditions like errors or data packets. This
allows you to specify desired trigger conditions and makes
finding errors or packet types easy by eliminating the need
to do manual searches of very long records.
Figure 8. Searching for PCI Express 3.0 errors quickly identifies
problems in the data stream.

Save Packet, Symbol and Waveform Data for Further Analysis
The N8816A Infiniium PCI Express 3.0 protocol analyzer software provides save capabilities for the symbol and packet lists
in easy-to-export .csv or .txt formats for analysis outside of the scope application. Since the packet decode is performed
on the real-time capture of the oscilloscope, the corresponding waveform can also be saved for future analysis in both the
oscilloscope and external tools.
