19 | Keysight | N5393D PCI Express® 3.0 (Gen3) Software for Infiniium Oscilloscopes - Data Sheet
Measurement Requirements
The PCI Express electrical performance
validation and compliance software
requires the E2688A high-speed serial
data analysis software, one of the PCI-SIG
approved compliance test fixtures (CBB
or CLB), and at least two SMA cables or
InfiniiMax active differential probes. The
N5393D optionally requires the InfiniiSim
waveform transformation toolset to enable
to de-embedding or de-convolving of
test fixture and cable losses based on
user supplied S-parameter descriptions

of these structures. Some of the
measurements cannot be made with the
PCI-SIG compliance test fixtures and may
require you to build or acquire a custom
test board, assembly, or other test fixture.
To purchase the PCI Express compliance
test fixtures, consult the PCI-SIG Web
site and select the PCI-SIG specification

Bandwidth requirements for PCI
Express
PCI Express operates at 2.5 GT/s, 5 GT/s
and 8 GT/s. Below are two tables that
provide guidelines on the minimum
bandwidth and sample rate required for
PCI Express Transmitter measurements.
In addition to transmitter measurements,
phase jitter measurements of the PCIe
100 MHz reference clock also call for a
minimum sample rate used to measure
the clock as is also shown below. Use
this information to help you select the
proper oscilloscope for your specific
requirements.
