This example demonstrates how to perform an eye scan on the Xilinx GTH transceivers on the PXIe-6593, and the Xilinx GTY transceivers on the PXIe-6594. This can be used to aid in debugging issues with the high-speed serial channels on these devices.
This example is built on top of the PXIe-6593/PXIe-6594 Aurora Streaming examples installed with the FlexRIO driver. The original versions of those examples can be found in the LabVIEW Example Finder.
Hardware and Software Requirements
LabVIEW 2020 or newer

PXIe-6593 or PXIe-6594
How to Use
Open the Acquire Eye Scan (Host).vi
Select your device under FPGA Resource
Select the path to the bitfile you want to use
A precompiled version of the FPGA VI is included with the example
Select which QSFP port and the lane on that port you would like to run the eye scan on
Adjust the Bit Error Ratio Floor and Step Size as desired
Run the VI
