1Introduction
This Quick Start/User Guide provides information using the GRL-PCIE-TX test solution to set up
and test an electrical transmitter (Tx) device for PCI Express (PCI-SIG SEG) certification.
The main body of this documentation describes how to configure the GRL-PCIE-TX solution to
capture and test waveforms in a PCIe 5.0 (or below) system (lane, data rate, preset), or
individual waveforms, and perform SigTest signal quality and de-emphasis compliance tests.
The test automation is carried out based on PCI-SIG-approved Methods of Implementation
(MOI’s) with high performance real-time oscilloscopes using existing PCI-SIG Compliance Base
Boards (CBB’s) and Compliance Load Boards (CLB’s).
The GRL-PCIE-TX solution consists of the GRL PCIe “GRL-P1” hardware controller and
automation software (GRL-PCIE-TX). The GRL-PCIE-TX software when run from the computer
or oscilloscope enables automation control to test the device under test (DUT) for Tx electrical
compliance. The GRL-P1 hardware controller is designed to work primarily with the software
to provide compliance toggle to control the state of the DUT. Alternatively, an arbitrary function
generator can also be used as a secondary option for compliance toggle control. The GRL test
solution also extends support for RF switch integration to automate switching or selection of
the lane under test.
The GRL automation control enabled PC or scope automates power and signal quality test
sequencing and processing of captured waveforms for the DUT at the selected PCIe data rate.
The Tx path is tested with worst case eye to ensure a Bit Error Ratio (BER) of less than 1E-12
can be achieved. When combined with a satisfactory level of interoperability testing, these tests
provide a reasonable level of confidence that the DUT’s will function properly in most PCIe
environments.
This documentation covers the following major components for PCIe Tx testing.
1. GRL-P1 hardware controller setup.
2. GRL-PCIE-TX software configuration and test setup.
Note: For manual test methodology, please refer to PCI-SIG SEG for approved vendor specific
Method of Implementation (MOI’s) as technical reference.

FIGURE 2. START PCIE TX TEST APPLICATION
3. To enable license, go to License→License Details.
FIGURE 3. SEE LICENSE DETAILS
a) Check the license status for the installed application.
FIGURE 4. CHECK LICENSE FOR INSTALLED APPLICATIONS
b) Activate a License:
•If you have an Activation Key, enter it in the field provided and select “Activate”.
•If you do not have an Activation Key, select “Close”to use a demo version of the software
over a free 10-day trial period.
Note: Once the 10-day trial period ends, you will need to request an Activation Key to continue
using the software on the same computer or oscilloscope. The demo software is also limited in its
capability, in that it will only calibrate the maximum frequency for each data rate. Thus, the demo
version cannot be used to fully calibrate and test a device. For Demo and Beta Customer License

automation control enabled Scope or PC.
10. On the Scope or PC, obtain the network address for the connected GRL-P1 from the device
settings. For example, if GRL-P1 is connected to the PC, open the Device Manager which
should detect the controller as a Controller Serial (COM) Port, e.g. “GRL PCIe34 P1
(COM10)”.
11. On the Equipment Setup page of the GRL PCIe Tx Test Application, type in the address of
each connected instrument into the “Address” field.
Then select the “lightning” button ( ) for each connected instrument.
The “lightning” button should turn green ( ) once the application has successfully
established connection with each instrument.

4Testing Using GRL-PCIE-TX
The GRL-PCIE-TX test solution supports automated Tx compliance testing using the SigTest
signal quality/de-emphasis and stress tolerance analysis application for PCIe system board and
add-in card DUT’s. In a typical test environment, the GRL-PCIE-TX automation software is run
from the PC/oscilloscope and communicates with the GRL-P1 hardware controller. This enables
automation control for the DUT’s power and signal quality test sequence, as well as waveform
acquisition (for PCIe Gen1, Gen2, Gen3, Gen4 and Gen5). Optionally an arbitrary function
generator can also be used as an alternative compliance toggle controller.
The GRL-P1 controller can be connected to either a PCI-SIG compliance load board (CLB) test
fixture for the system board DUT or compliance base board (CBB) test fixture for the add-in
card DUT. The GRL automation control enabled PC/Scope will send commands to GRL-P1 which
controls the power to the DUT and provides a compliance toggle signal to cause the DUT to
enter the next compliance state.
The DUT will transmit the test signal to the oscilloscope that is used to validate the test pattern
of the signal. The compliance signal will be captured and saved as a waveform file which is then
measured for stress tolerance and preset test compliance. In between, an optional RF switch
can be used and controlled by the GRL-PCIE-TX software to automate selection of the lane
under test. When testing is completed, the software will generate a test report detailing all
results from all lanes tested.
4.1 GRL-PCIE-TX Advantage
The GRL-PCIE-TX test solution provides a more efficient way to perform PCIe Tx compliance
testing rather than using traditional manually-driven methods that are generally both time-
consuming and error prone, tying up valuable equipment and resources.
To increase test efficiency, the GRL-P1 controller will first quickly capture waveforms on the
oscilloscope. Then using a separate computer, the GRL-PCIE-TX software will run PCIe
compliance tests for the waveforms, SigTest signal quality, and de-emphasis.
Through this offline processing of captured waveforms, the oscilloscope can be freed up for
other work. The test time can also be further reduced with the software’s multi-threading of
SigTest. Another advantage is that GRL-P1 can be programmed to automatically capture only
the waveforms for the test that the user wants to perform.
4.2 Set Up DUT Tx Test with Automation
Once pre-configuration has been completed from Section 3.3, continue with the test setup. The
following procedures show how to set up the test environment to perform automated Tx
compliance testing for both the System Board and Add-In Card DUT’s.
4.2.1 Connect Equipment for System Board DUT Test
The connection diagrams below show the recommended equipment setups to perform
waveform acquisition and analysis for the PCIe System Board DUT using a GRL automation
control enabled Scope and different test controller methods.
