  • Example of reference for PCIe Data Streaming double 6537 s disc

    Hello world

    I have successfully changed the example of reference for streaming ( http://zone.ni.com/devzone/cda/epd/p/id/5315 ) for the card PCIe-6537 UNIQUE and able to write to the clock speed of 20 M (at end of initial test) without any error.

    However, I don't know how to view the *.bin file to check whether I wrote the right data. I saw an example VI called 'read the binary '. However, it is said "File already open" and gives a GPIB controller error (very odd). Should I try using MatLab? I doubt that this will help because it seems that the file write VI does not close the file correctly.

    I have attached the updated UNIQUE PCIe-6537 source code and the file with this post error. There are file support as well for writing file window live

    I'm the kind of new acquisition continuously and at high speed. Please let me know if I'm missing something. Thanks in advance.

    See you soon,.

    I have a few links you can go to more resources continuous here and here.

    The original question, you have posted using binary VI reading won't be able to because of the memory.  You can read more small segments of the file and keep the file intact.  There are a number entry that indicates the number of data items are returned by the function.  If you want to save multiple files, you can use any looping function to make it work, just set the condition to find out how much time and when to stop.  I don't know of a quick example that does this.  You read again all the data, but given that the readings are in small pieces, it will help the issue given that the data are not need a large space contiguous memory to reside in during playback.

    Data compression would be more than a post processing step rather than a step continuously, and it can slow down your stream if you were writing at the same time after your reading.  In producer/consumer architecture, you could read in the data and compress it before the record in a file, which would not affect the performance of your reading, it forms the data and create a file that is smaller and takes less space in memory.

  • T510 disabling client screensaver

    Hello

    I'm having a little problem, I have a T510 client that is supposed to display certain information, but without being interaction with users. However, it continues to go into screen saver mode. I tried to disable the screensaver via the Admin account, but it is not the effect it is connected on the user account. So it goes in screen saver after about 15 minutes.

    Is there a way to disable the screensaver for the user account?

    Thank you.

    Hello

    can you please indicate which operating system you use it the T510.

    The t510 may be provided with Smart/WES/ThinPro zero. Options depend on the operating system.

    A proposal, I think that you are talking about WES7.

    The screen saver is controlled by registry settings. You find many good references for the parameters of screensaver on the net, for example www.windows-commandline.com/disable-screensaver-registry-settings/

    While the parameter you need is "\Control Panel\Desktop\ScreenSaveActive", you need to change that to "User" account and not the administrator.

    Some steps below to change the settings for 'User' reg while signed in as 'administrator '.

    1: logon as administrator

    2: run Regedit

    3: put "HKEY_USERS" highlighted in the file menu, select Load registry. Point of "C:\users\user\ntuser.dat" give the key any name you like.

    4: Browse this registry hive newly added, find the key "\Control Panel\Desktop\ScreenSaveActive" and update the value as described above.

    5: select the name that you gave the new registry hive in step 3 and from the menu, select 'File' "Unload" click Yes to confirm the unloading.

    6: close regedit

    7: validate changes using the Green padlock next to the clock.

  • I can't understand the reasoning behind the tables to ID CS5. Can you help me?

    I can make tables ID CS5 works, but I do not understand how they work. I should mention that I am a heavy user of FrameMaker, so I'm sure I have some faulty assumptions.

    In FrameMaker, I'm used to the use of the table styles to automate the formatting of the table. All the table set in the form of information - for example, styles of text for titles table, headers, and body; rules; intercellular. etc. - is built in the style of table and applied with a single click. The text style information drawn from pre-existing paragraph styles that are associated with the table style. All very simple. But in InDesign, things seem much more complicated.

    InDesign a of table and Cell Styles. I'm not clear on the relationship between the two. You can specify to power and styles of shading in both. I don't understand this.

    I got more predictable results, with cell Styles, so I took most of my formatting information. But Cell Styles are not autonomous entities. Even if you create them, then add them to the Style Table, they must be associated with a pre-existing paragraph style. This looks like a duplication of efforts - two distinct styles (cell and paragraph) apply the same text formatting information. The cell Style includes power and info of the shading, but that shouldn't be necessary since that information can theoretically be entered in the Style of the Table.

    In addition, Cell Styles using limits you to the style of a paragraph per cell. In some cases, I need two - data or text, followed by a few chips. When this happens, that I had to remove the cell Style and directly apply a paragraph style. Looks funky.

    I don't want to get too deep into the weeds with specific puzzles I encountered; It is sufficient to say that I do not understand how the table and Cell Styles interact and how best to use them to create and format tables efficiently. Does anyone of you understand the reasoning behind the ID tables? Can you provide a source that explains it? There must be a system, a set of operating principles that are consistent, but I was not able to discern them.

    Sincere thanks,

    -Donna Reynolds

    Hi, Donna.

    I don't know a good reference for how table styles fit together, but I think that your problems would be solved more easily if you gave a specific example of what was confusing you.

    It is true that there is overlap between the table and cell styles. This is because they are modeled on the Table Options and Options of the cell, and there is an overlap. For example, the shot of the table and the outer race of the external cells are the same things.

    Most of the time, you can avoid this confusion - in the Style of your Table, do not define anything except for where you need to replace your cell style information, such as the outside of the table. You cannot set the padding on a style to a table in the table, because you cannot set the padding in the Table Options. Except for the stuff that relates to the entire table, such as the alternation of the contours of row/column.

    So set your fillings in cell styles and use this style in the Style of the Table.

    In your cell styles, do not specify a paragraph style. Use (ignore). It is important that a cell should dictate a particular paragraph style, then use it. But it's probably him better not reach otherwise.

    Is it that help at all?

  • Oscilloscope for the acquisition of data from the usb-6009 or - example of temporal division for 5 seconds, 10 seconds

    Hey Hey everyone

    I was looking for an example for two-channel oscilloscope virtual using e/s all-in-one of the 14 bits of NI DAQ USB 6009. I tried to research for example BOF time division or s/div for 1 second, 5 seconds, 10 seconds.  but was shocked to find that there is no reference for it. The range of oscilloscoper virtual

    Minimum - 10 micro s / div maximum -10milli second div but there is no example for 1 second / div or 5 seconds / div...  If anyone can guide me. I'm new to labview environment.

    This is the oscilloscope two sample obtained from google search. is there material limitations. ?

    I'm working on continuous 4-channel data acquisition data acquisition using niusb 6009

    The sampling frequency is sufficient for any desired s/div. The sample rate is 12 ksamples / s per channel, so if that meets the Nyquist criteria for the input signal, you can capture it. The number of samples has no effect on that with the exception of the amount of the signal you acquire. Your chart is not stable, if you do not trigger the acquisition. Even as real significance, therefore your emulation seems actually successful.

  • Sample clock dependence with small signals data acquisition

    Hi all

    I use a NOR-9205 on a NOR-cDAQ-9184 and noticing some interesting dependencies of waveform on my sampling rate selected. It seems that small changes in the sample clock frequency have a significant impact on the measured waveform.

    Quick background, I am in a position a signal with a ripple of mV ~ 10 with V 1.6 bias. I'm not interested in DC, only the AC signal but the NOR-9205 has only DC coupling. The application is a circuit where I expect simulations noise past the circuit must be greater than the higher noise frequencies. In the waveforms attached the background plot is the applied signal, and the top graph is the signal arising after that the signal was mostly annihilated. The two waveforms are measured with the NOR-9205.

    I am aware that this measure is less than the precision of the NOR-9205, which has a maximum precision of ~ 3 mV in his +/-5V range. However, if I can't at least on the basis of shape which is good enough for me. I'm also now pretty curious that data acquisition is actually to create this

    My best idea, is that it is a product of internal multiplexing of the 9205 with the DAC.

    The first plot shows the waveform at 20 000 Hz, which is what I expected:

    The second shows the waveform at 20 001 Hz, which seems to be modulated with a backup sawtooth:

    The waveform looks as expected for 20 000, 20003, 20004, 20005, 20008, 20009, 20010 and Hz 20011. The waveform looks like modulated to 20001, 20002, 20006 and Hz 20007.

    Ideally, I would like to understand this problem so that I can configure the measure in a stable way that I can count on the basic shape of the wave. Has anyone seen something similar?


  • Sampling frequency for the output of an acquisition of data USB-6211 card?

    Hello-

    I use a CGI CMOS FireWire camera to read an interference figure, then using a transformed of Fourier transform spectral interferometery (FTSI) phase recovery simple algorithm to detect the relative phase between the successive shots.  My camera has a linear 28 kHz scan rate, and I programmed my phase retrieval algorithm take ms ~0.7 (of a trigger of camera at the exit of the phase). I use the live signal to control a piezoelectric stack, by sending a voltage single sample to the analog output of a data USB-6211 acquisition card.

    Send this output voltage increases the time of my loop 4 m, I would really like to achieve a 1 kHz or better sampling rate. Is the problem with my DAQ card or with the processor in my computer? The DAQ cards of NOR can support these speeds?

    Thank you

    -Mike Chini

    Hey Mike,

    With USB, your loop rate will be around or under 1 kHz, even on the best of the systems. USB has a higher latency and less determism PCI and PCIe. You can get rates AO one much better sample on a PCI card, potentially a PCI-6221. We have a few HAVE points of reference for targets of RT for PCI, / AO in a loop, you should be able to get similar performance in Windows, but if you do a lot other treatments may suffer from your local loop rates.

    Hope this helps,

  • acquisition of data with different sampling rates high

    I have a few questions on the use of the OMB-DAQ-3005 with different sampling rates high.

    For our application, we have 8 analog inputs. Which two are a quick response and should be sampled frequently.  We have an encoder quadrature (CPR 1000 running at 1800 rpm).  We plan to sample X 4 encoder.  For the analog inputs for the quick response, we want to trigger a sample of each pulse or each a few pulses, thus creating a timestamp with the position of the encoder with respect to position index as well as two fast analog inputs.  We have data correlating the analog inputs with the position of the encoder.   Other analog inputs, we want to measure relatively slowly (for example once every 5 dry or similar).

    How can I go on the configuration of the two (or more) sampling rates different wherein I can taste entered at different frequencies?  Also, is there a way to reset the encoder count after outbreak of the index as I have the position of the encoder with respect to the index?

    Maybe you'll find someone here who uses the OMB-DAQ-3005, but this forum is really more designed for LabVIEW programming issues.

    I've never used the OMB-DAQ-3005, but out of curiosity, I took a glance at the Manual of OMB-DAQ-3005.  The answer to both your questions are:

    1. you cannot run a hardware DQA Multiplex (like this one) at independent rates by channel.

    2. the OMB-DAQ-3005 supports an Index Z feature to reset the counter - look for documentation on how to configure any software interface you are using.  If you get stuck, you can try to discover media appropriate for instrument channel.

    Best regards
