PCIe PLL BW Transmitter Test Application Help 6
Welcome
The PCIe PLL BW Rx application performs the test as per the PCI Express Base Specification Revision 5.0.
Welcome
Figure 1: TekRxTest - PCIe PLL BW Rx application
PCIe PLL Bandwidth and Peaking test is accomplished by connecting the output of BERT PPG (which can produce specific PCIe PLL
BW test patterns) to the input of the DUT through a specialized set of fixtures and cables. The BERT can be programmed to add different
amounts of sinusoidal jitter at the configured SJ tones to a reference clock waveform. Output of the DUT is connected to the RT Scope to
measure how much SJ passes through the DUT's Tx PLL for a certain SJ tone. Upon performing the process across multiple tones gives
us the PLL frequency response indicating the PLL Bandwidth and peaking.
Key features and benefits
• SJ Amplitude Calibration and PLL BW test comes as a part of the receiver solution.
• Jointly with Anritsu BERT MP1900A series, the solution provides the tools and flexibility required to observe real-time performance for
PLL BW devices for PCIe Gen3, Gen4, and Gen5
• Reliable and accurate results reduce the test execution time and minimize the skillset required to perform calibration and testing.
• Detailed reports are at one’s disposal for the calibration and test modules.

Operating basics
Operating basics
Launch the application
To launch the PCIe PLL BW TekRxTest application, click the shortcut icon TekRxTest on the desktop and select PCIe PLL BW Test in the
application window.
Close the application
To exit the application, click on the application title bar. Follow on-screen instructions to save the unsaved session or test setup.
Note: Using other methods to exit the application may result in abnormal termination of the application.
Launch Real-Time Oscilloscope
The TekVISA Socket Server application on the oscilloscope provides the necessary connectivity between the TekRxTest application
and scope. Although it is launched in the background when the scope boots up and the socket is initialized for communication, it is
recommended to verify the status by clicking on the Desktop Tray ―› TekVISA LAN Server Control as shown in the image below. If it is
ready to exchange data, then a wizard would appear as in the below image.
Figure 2: Launch Real-Time Oscilloscope
In the unlikely event when the socket is not initialized, the process can be started by clicking on “Start Socket Server” which
Note:
gets enabled during such a scenario.
