Preface
List of Terms
The following table lists terms that appear in this manual. For a more extensive list
of PCI Express-specific terms, refer to the latest PCI Express Base Specification
document.
Table i: Terms used in this document
Term Description
Link A connection between two PCI Express devices. A link consists of
a number of lanes. A link described as by-N (or xN) consists of a
number (N) lanes.
Differential Pair A set of two signals, positive and negative, transmitting data from
one device to another.
Lane A single differential pair (two signals) that transmit data in one
direction of a PCI Express Link. A unidirectional lane.
Root complex A device (or other element) (typically a controller hub) that is located
closest to the connection between the I/O system, the CPU and
memory.
Upstream Relative device location:
The relative position of a device (or other element) in a system
where the device is closer (topologically) to the root complex.
Examples: The port on a switch that is closest to the root complex is
the upstream port. The port on an endpoint or bridge component
is an upstream port. The upstream component on a link is the
component closer to the root complex.
Relative direction of data flow:
The direction of data flow where data is flowing towards the root
complex.
Downstream Relative device location:
The relative position of a device (or other element) in a system
where the device is farther (topologically) from the root complex.
Examples: The port on a switch that is farther from the root complex
is the downstream port. The upstream component on a link is the
component closer to the root complex.
Relative direction of data flow:
The direction of data flow where data is flowing away from the root
complex.

Introduction
The TLA7S08 & TLA7S16 Serial Analyzer modules are tools used to acquire and
analyze data traveling on a PCI Express (PCIe) Gen1 or Gen2 serial bus. The
serial analyzer modules can be installed in either a Tektronix portable or benchtop
logic analyzer mainframe. Specially designed probes connect from the module to
a circuit board in your system under test (SUT), or to a PCI Express card device.
Figure 1: TLA7S16 Module and P6716 midbus probe
Product Description
Tektronix provides two different serial analyzer modules. Both modules can
acquire PCIe Gen 1 and Gen 2 data. They provide packet-level triggering,
sequence triggering, and error triggering. The modules can acquire up to
32 million 8b/10b symbols. The main difference between the modules re the
number of input channels.
TLA7S16 16-Channel Serial
Analyzer Module
The TLA7S16 Serial Analyzer Module supports x1, x4, and x8 bidirectional
PCIe links and x16 unidirectional links.
TLA7S08 8-Channel Serial
Analyzer Module
The TLA7S08 Serial Analyzer Module supports x1 and x4 bidirectional PCIe
links and x8 unidirectional links.

Introduction
Front Panel The front panel provides indicators for checking the basic status of the serial
analyzer, four probe connectors, two probe power connectors, and four connectors
for a reference clock. (See Figure 3 on page 4.) A description of the indicators
and connectors is provided. (See Table 1 on page 3.)

Introduction
Table 1: Front panel indicators and connectors
Item
number Indicator or connector Description
1 READY indicator The READY indicator lights continuously after the serial analyzer module successfully
completes the power-on process. If the indicator fails to light within five seconds of
power-on, an internal module failure may be present.
2ACCESSED indicator The ACCESSED indicator lights anytime the controller accesses the serial analyzer
module.
3 ARM’D indicator The ARM’D indicator lights when the serial analyzer module is armed during an acquisition.
4TRIG’D indicator The TRIG’D indicator lights when the serial analyzer module triggers and stays on until
the module finishes acquiring data.
5Probe connectors Four connectors in the module accept the probe(s). Each connector is labeled A, B, C, or
D. The letters correspond to the graphic display in the Setup window.
6Reference Clock Input
connectors
Two SMA connectors (labeled + and –) provide clock input connections from the SUT
or from another module.
7Reference Clock Output
connectors
Two SMA connectors (labeled + and –) provide clock output connections to another
module.
8 Probe Power connectors The probe power connectors provide power to the probes.
Rear Panel The serial analyzer rear panel provides rear-panel connectors to connect the
module to the mainframe. The rear panel also includes two logical address
switches. Tektonix recommends that you leave the switches at the default switch
setting of FF (Dynamic Auto Configuration). When the switches are set to FF, the
instrument automatically sets the address to an unused value.
NOTE. Do not set any module to logical address 00. Logical address 00 is
reserved exclusively for the controller.
