The deserializer accepts the serial stimulus data and outputs the expected data. Copyright © 2012 Published by Elsevier B.V.

That would make more sense to me. BER vs.
Please try the request again. The DWE offers a configurable software environment for creating digital vectors. Your cache administrator is webmaster. Bit Error Rate Test Equipment The NI PXI-6552, which is used for this demo, has features such as Hardware Compare, which perform on board comparisons between generated signals and acquired signals.

If this property is set to "Stimulus and Expected Response" or "Expected Response Only", the generation engine sends the expected data to the FIFO, to be compared with the acquired data. Synchronization For most digital tests performed on semiconductors, synchronization is a requirement, whether it is between the board and the DUT or even between generation and acquisition sessions.
Conclusion National Instruments high speed devices are ideally suited for applications such as BERT. Bit Error Rate Test Set Generated Sun, 02 Oct 2016 13:05:24 GMT by s_hv902 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.7/ Connection The hardware compare feature enables the device to utilize the on board FPGA for comparison of data. Deserializers take in serial digital data and output parallel data based on the serial input.
Hardware Setup This reference architecture uses the NI PXI-6552 to conduct the BERT test. This allows for real time hardware comparison, which is not possible if data is transferred back to the host computer. Bit Error Rate Tester Agilent Generated Sun, 02 Oct 2016 13:05:24 GMT by s_hv902 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.5/ Connection Bert Bit Error Rate Tester Testing for BERT requires a bit generator or a test pattern generator, and a receiver, which is used to compare that pattern.
Amaral et al. Step 9: The calculation of Distribution of errors is done in software. Proceedings TWEPP 2009. navigate here The Expected Data is also loaded into the on board FIFO, which will later be compared (on the FPGA, real time) to the data that is read in.
Step 4: To set up hardware compare on the digital board, property nodes are used for both the acquisition and generation sessions. Stratix II GX EP2SGX90 Transceiver signal integrity development board: reference manual. As seen in the image below, the stimulus data is loaded onto the onboard memory to be generated.
Based on the number of parallel channels that the deserializer outputs on, input channels will be configured appropriately on the high speed digital board. Some external connections need to be made to synchronize the generation and acquisition sessions. Results of the BER reading are displayed on the graph on the front-panel. Back to Top 6.
Figure 5: Front Panel of Hardware Compare BERT VI NOTE: By default the attached LabVIEW VI is set to run as a loop back test. The system returned: (22) Invalid argument The remote host or network may be down.

Step 6: For the generation session the NIHSDIO Configure generation repeat VI is used to continuously generate data. The hardware-compare feature on the NI PXI-6552 is uniquely suited for BERT testing as it provides the ability to perform digital comparisons of data on device itself. Back to Top 4. The diagram below shows the external connections that are required.
