Features
The PCI Express electrical test software
PCI Express compliance testing
offers several features to simplify the
validation of PCI Express designs:
– PCIe 3.0 measurements for
uncorrelated TJ, DJ, and PWJ, pseudo
package loss, and preset de-emphasis
and preshoot.
– Automated 1.6 M Unit Interval (or
greater) testing for highest accuracy
when embedding PCIe reference
channel and package model losses
– Results consistent with PCI-SIG
SigTest software utility
To pass signal quality testing at a PCI-SIG-sponsored compliance workshop, your
product must successfully pass “Gold Suite” testing, based on the PCI-SIG SigTest
application. The SigTest application tests your device against the minimum signal-quality
performance requirements for PCI. If you are developing receivers and transmitters for
add-in boards and system motherboards, the PCI Express electrical test software helps
you execute the SigTest tests and additional oscilloscope already completed tests. See
the list of tests in Table 3 on page 16 (for 1.1 test coverage).
While SigTest tests provide a good overview of PCI Express electrical signal quality,
they address only a small subset of the electrical compliance measurements specified
in the PCI-SIG specification. The SigTest application also provides minimal reporting
capability with pass/fail indication and measurement values, and has limited debugging
capabilities to decipher eye mask violations or excessive jitter.
– Support for de-embedding of test
fixtures and cables 1
– Test setup wizard for ease-of-use
– Wide range of electrical transmitter
and reference clock tests
– PCI-SIG SigTest clock recovery
algorithm
– Optional integrated receiver test

For PCI Express 3.0 measurements, the software automatically calculates uncorrelated
total jitter, uncorrelated deterministic jitter, uncorrelated PWJ necessary for validating
new PCIe 3.0 compliant chipsets. For versions of devices compliant with PCI Express 2.0
or earlier, random jitter is also reported for completeness and a voltage margin “eye”
diagram is included in the final HTML report. DJ and TJ values are specified in the PCIe
2.0 specification and are required for compliance verification.
– Automated scope measurement
setup
– Test results report generation
– Pass/fail margin analysis
– Reference clock phase jitter analysis
– Two-port (explicit clock and data)
supported for motherboard signal
quality testing
– Support for both full-swing and
low-power, half-swing devices.
With the PCI Express electrical test
software, you can use the same
oscilloscope you use for everyday
debugging to perform automated testing
and margin analysis based on the PCI-
SIG-specified tests.
Figure 1. PCI Express 2.0 supports data rates up to 5.0 GT/s as shown above (–3.5 dB
de-emphasis).
1. Requires the purchase of the optional Keysight
InfiniiSim Waveform Transformation Toolset
for Infiniium Oscilloscopes.
2. Requires the purchase of N5393D-4FP
software license. Receiver test hardware and
fixtures not included and must be purchased
separately.
