As you can see in Figure 2, we injected an Error at time 4 seconds by hitting the “Error Add” button. Obviously this is not going to work for a lot of packets so we need software that can detect errors on the bit level and give us statistics based on them. Do you know of an easy way to get the bit error rate using Capsa? –rhololkeolke Aug 23 '11 at 1:30 add a comment| up vote 0 down vote You need This location array is then passed to a General Histrogram.vi subVI which builds the graph to be displayed on the front panel.

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. Fortunately, in most cases we need only to test that the BER is less than a predefined threshold. Please try the request again. 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.

Please explain the local library system in London, England What type of sequences are escape sequences starting with "\033]" Did Donald Trump call Alicia Machado "Miss Piggy" and "Miss Housekeeping"? Is this safe to display MySQL query error in webpage if something went wrong? The number of bits required to accomplish this will only depend on the required confidence level and BER threshold. On the generation side the sample clock must be exported to the ClkOut pin on the Digital Data and Control Connector (DDC) by connecting the ClkOut pin on the Digital Data

Using nested for loops, the locations of the errors are checked and stored in the shift registers. On the high speed digital board, channel '0' can be configured for output. As seen in the image below, the stimulus data is loaded onto the onboard memory to be generated. Bit Error Rate Testing Then the appropriate Hierarchical Waveform Storage (HWS) file containing the stimulus data is chosen on the front panel of the attached LabVIEW virtual instrument (VI).

What is the sh -c command? Step 3: The trigger is accepted in the acquisition session by using the PFI 2 line for triggering the start trigger. Back to Top 5. Step 2: A trigger will have to be shared between the generation and acquisition sessions for complete synchronization.

Back to Top 4. The DWE offers a configurable software environment for creating digital vectors. One of the most important ways to determine the quality of a digital transmission system is to measure its Bit Error Ratio (BER). navigate to this website 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

Software Setup The software used in this system is architected using NI LabVIEW and the NI Digital Waveform Editor. Figure 2 – Hardware Set up The stimulus data that can be seen in the diagram above can be created programmatically in a language such as NI LabVIEW, or an easy 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.

The deserializer accepts the serial stimulus data and outputs the expected data. Just trying to save you some time. –boot13 Aug 22 '11 at 19:19 Okay, I'll take a look at it. First, the Digital Waveform Editor (DWE) must be used to create the stimulus data. Rosa Parks is a [symbol?] for the civil rights movement?

The confidence level is the percentage of tests that the system’s true BER is less than the specified BER. Your cache administrator is webmaster. The calculated result is the ratio of errored bits to the total number of transmitted bits usually shown in an exponential form, such as 2^B, where B is the BER ratio. share|improve this answer answered Aug 19 '11 at 18:49 charlesbridge 921611 This is interesting and potentially useful, however, the errors are at a packet level and I need something
