Bit Error Rate Tester Software

BERTScope® DPP Series Digital Pre-emphasis and LE Series Linear EqualizerCondition the test pattern signal by adding controllable amounts of pre-emphasis for use with a Bit Error Rate Tester. The deserializer takes in fast serial data and outputs slower parallel data, thus making it easier to acquire the parallel data (on a higher number of channels). Generated Sun, 02 Oct 2016 13:04:02 GMT by s_hv978 (squid/3.5.20)

The deserializer accepts the serial stimulus data and outputs the expected data. It's vague about what errors, but according to this post on Stackoverflow it does record CRC errors.

I am currently trying to test to see whether this software does what it actually is supposed to do, so that it can be used in some network simulations.

Step 5: In the acquisition session, the 'Fetch Relative To' property should be set to 'First sample', and also a Reference trigger should be configured, which is never sent to set

In order to determine the test time required, the number of bits to be tested is simply divided by the data rate ( ). Bit Error Rate Tester Agilent Here’s the page we think you wanted. The parallel data is then read in on the input pins on the NI PXI-6552 and compared with the expected data stored on the FIFO. What is the sh -c command?

Acceptable Bit Error Rate

Keysight offers the broadest portfolio with four BERT families that address a variety of speed classes, usability concepts, and flexibility as well as application specific stimulus and analysis tools. Skeletal formula for carbon with two double bonds Why did companions have such high social standing? Bit Error Rate Tester Software The first thing is to set up the Error Detector for your particular configuration. Bit Error Rate Pdf BERTScope BSA Series 8.5 - 28.6 Gb/s 1 Serial bus compliance, precise jitter tolerance for OIF-CEI, advanced BER-based analysis and optical datacom system test.

Step 1: To conduct the BERT test the acquisition and generation sessions on the digital board must be synchronized. click site Step 7: Once the set up is done, the NIHSDIO HWC Fetch Sample Errors can be used to fetch all the errors that occurred. Using the NI-HSDIO driver, data such as the error locations, number of errors, and total samples compared can be read back from the on board FPGA. Since this is a statistical process, the measured BER only approaches the actual BER as the number of bits tested approaches infinity. Bit Error Rate Calculator

For this BERT test, it is important to synchronize the generation and acquisition sessions because hardware compare is used to check for bit errors that occur on the expected data. The confidence level is the percentage of tests that the system’s true BER is less than the specified BER. share|improve this answer answered Jul 9 '13 at 19:06 LawrenceC 46.7k677144 add a comment| up vote 0 down vote I'm not certain it will give you what you need, but the http://sovidi.com/bit-error/bit-error-measurement-rate.php 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.

Results of the BER reading are displayed on the graph on the front-panel.

Please try the request again.

Conclusion National Instruments high speed devices are ideally suited for applications such as BERT. I think the best you can do is test an Ethernet circuit using software and then check for interface error stats, drop/ooo packet counters and so on. See search results instead: United States United States 中国 日本 台灣 한국 Россия Brasil Canada (English) Canada (Français) Deutschland France India Malaysia United Kingdom more... Bit Error Rate Example Step 9: The calculation of Distribution of errors is done in software.

Resulting in the equation:At a standard 95% confidence level, we can substitute .95 in for CL and obtain a very usable function:A table of test times at 95% confidence level is According to our calculations above in Table 1, we would need to measure zero errors for ~2 mins at this data rate to ensure a BER of less than 10-11.

First, the Digital Waveform Editor (DWE) must be used to create the stimulus data. PatternPro PPG Series 12.5 - 40 Gb/s 1, 2, 4 High speed, multi-lane/multi-level patten generation for advanced component characterization and optical datacom system test.

Wireshark will give you the same information, but you typically have to work harder to get it. Just trying to save you some time. –boot13 Aug 22 '11 at 19:19 Okay, I'll take a look at it. The system returned: (22) Invalid argument The remote host or network may be down. The number of bits required to accomplish this will only depend on the required confidence level and BER threshold.

Back to Top 6. This may include Differential/Normal transmission and/or clock data recovery.

Looking at the link it just seems like an alternative. –rhololkeolke Aug 22 '11 at 16:29 Mainly it's easier to use. An example of a semiconductor device for which a BERT test would be useful is a deserializer or SerDes. An external connection also needs to be made between the lines PFI1 and PFI2 on the DDC. 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.

Using the NI-HSDIO driver API for LabVIEW, the high speed digital board can be programmed to utilize the hardware-compare feature for BERT. Overview This document discusses the details of Bit Error Rate Testing (BERT) testing using National Instruments hardware and software. This allows for real time hardware comparison, which is not possible if data is transferred back to the host computer. Deserializers take in serial digital data and output parallel data based on the serial input.
