Default sampling frequency NI9235/9236 equipment in scan mode.

Hello

I am currently using NI9235 with cRIO under scan mode, which allows sample rates up to 500 Hz. I realize that the card module has 12.8 MHz internal and under mode FPGA software and hardware time base combined anti-aliasing filter will be adjusted automatically depending on the installer of data rate, which is a set of values from 10 kHz to 794 Hz. Unfortunately, I do not have the FPGA package for now.

My question is that what will be the flow of material data, if NI9235 the samples at 500 Hz in the scan mode. The anti-aliasing filter still works just below half the data rate material?

Hello Marco,.

When it is used in scan mode the 9235 and 9236 are configured to sample at 10 KHz.  Unfortunately, this parameter is not configurable in scan mode.

Let me know if you have any other questions.

  • Change the frequency AO AO DC voltage scanning scan?

    Hi all

    I am very new to labview, but find the forums and examples extremely helpful. I probably spend 50 + hours to familiarize myself with tutorials and general information, but I am at a point where I need your help.

    I'm unable to change the example "AO frequency sweep" found here (see custom_sweep_1.VI) to allow me to sweep the voltage.  My instinct is that I don't need of the ' waveform buffer generation VI ' and that I should be able to remove the associated entries since I'm only interested in a sweep of DC voltage. It is also called create_log_frequencies.VI, and I'm fairly certain that I can use it as written and simply change "frequency", "tension". My work of the custom_sweep_1 changes are attached as custom_sweep_Voltage.

    The problems I am having with the edition of custom_sweep_1 are:

    (1) I don't think I understand very well how or if the parameters associated with waveform buffer generation VI relate to a sweep of DC voltage.

    (2) an extension of 1): the loop depends on the samples and Cycles by buffer and I don't know how / whether to replace these values

    (3) the .VI DAQmx Timing (sample clock) receives its sampling frequency of output waveform buffer generation VI, but I think I can use 1/scan time to replace this (?)

    (4) the DAQmx Write.VI gets waveform buffer generation data, but if I can get around this VI and AO tension of wire directly to write DAQmx then I think I can use minimum voltage as my entry of data (?)

    (5) after the implementation of these changes, the custom_sweep_Voltage runs, but I get error 200609:

    "The possible reasons:

    Generation cannot be started because the size of the selected buffer is too small.

    Increase the size of the buffer.

    Choose the size of the buffer: 1
    Minimum required buffer size: 2

    "Task name: _unnamedTask<3A>"

    I also note that I tried other ways to create the sweep of voltage DC VI:

    (1) I have tried change the tracer IV example (found here), but it's much more confused than change the frequency sweep.

    ( This tutorial and sample 2) block diagram looks like straighforward, and I also work on understanding what Assistants DAQ 1,2, 3.

    Any return would be great. I think it is clear that at the very least, my poor understanding of 'buffer' is if the cause of my confusion about the change of frequency scan, please do not hesitate to share any information you have.

    Thank you very much for the help,

    Additional information on my project/progress using labview follows below:

    My final goal is to determine whether or not the resistivity of a sample of organic driver changes over time. For this I want to compose a VI simultaneously sweeping the output voltage DC-5 to 5V periodically during 24 hours and measure the voltage drops to my load resistance (to determine the current in the circuit) and the sample. I use a USB 6259 DAQmx and that you have correctly configured my circuit. I work two screws that I created with the DAQ assistant and by changing some of the examples, I found online. Output voltage (of an AO) but I have to manually select the voltage value. The second reads voltages in three samples of interest and writes the data to a PDM file. If you've read this extreme sensation and still make a contribution, my next goal after finding how to sweep the voltage is to combine this with my VI measure VI. I think it will be relatively simple, but still, I rejoice in all your comments!

    I solved this problem. I have changed my approach to be similar to the last link in my post. AO frequency scan approach is much more complicated that I need. Thanks for the help.

  • High speed continuous measurement of encoder with sampling frequency of 1 kHz

    I am able at all times the position of a linear encoder using a PCI-6602 counter card, and I need to know how to set up so that the counter rotating at high speed, but the data is inserted into the buffer at a frequency of 1 kHz.  I am able suddenly to a hydraulic cylinder, and I am not concerned about the event recording to high frequency except to the extent where they throw off the number considerably if the equipment does not run fast enough to detect all the impulses of the encoder.

    Now, I think is that the external sample clock signal control (routed internal pulse output counter) time rate whereby the equipment detects the impulses of the encoder and the rate at which it inserts data into the buffer.  With a pulse 100 per inch encoder and a sampling frequency of 1 kHz, the extended final position of the cylinder is turned off by +/-0.15 inches, which is unacceptable.

    I need calculate a speed of this information, so I prefer not to use software timed sampling to control this (it's more difficult programming for other reasons as well - several asynchronous measures).  Any ideas on how to configure the hardware to count faster than the speed at which she inserts counties in the buffer?

    OK, you're clearly on the right track here, so I will focus on some details.

    1. How do you know that the +/-0.15 "differences are * measurement error rather than * error of movement?  Why wouldn't be an accurate measure and a proposal which can vary slightly from the nominal value?

    2. I wonder some all electric noise and defects that may produce false edges.  The fact that the behavior was better by using a sampling rate limited (200 kHz) in the digital inputs may be that some of these flaws were so short that they were never captured.

    I did a ton of work with the Commission to 6602 encoder and I can certainly confirm that count equipment is sensitive to the edges in a few tens of MHz.  (I know its 80 MHz for edge counting, but I think I remember that it can be of the order of 20 to 40 MHz to accommodate the time of signal propagation extra of the quadrature decoding circuit).

    A small point of clarification.  You're talking about the speed at which the meter "works to.  The value of count is a register whose value is changed completely by the circuit, * independent * of the sampling frequency.  If you enjoy with material-clocked County in memory buffer or interrogation of software without buffer not a bit for circuits that increments / decrements the value of the counter register.  (In other words, I am completely convinced that you would get commensurate with position end even if you took only 1 sample software-polled after the end of the move instead of sampling at 1 kHz all the way through.)

    So, if the value of the counter is disabled, it is because the circuit detects producers of County of the edges that shouldn't be there.  Something you can try is to set up digital debounce filter for input lines of the PFI corresponding to the encoder Source inputs and to the.

  • DAQmx task Read DAQmx with sampling frequency of 10 Hz produced much too much data

    I have a simple configuration with a strain of channel 4 OR-9237 amp holds a carrier of series C of WLS - 9163 (wired ethernet mode) - Details probably does not matter.

    I used MAX to create a DAQmx task associated with which all four gauges samples.  The calendar setting is "Scan Loads" is continuous sampling, 2 k buffer (read samples) and 10 Hz rate.  I guess that this task would generate 40 data values per second - 10 for each channel.

    I have a simple loop of reading using DAQmx Read.vi that works always (without any stimulation time).  Playback is set to read all available data and then pump it into a table.
    In the attached example, I also added a few words of debugging to stop the loop after N iterations.

    As the loop is programmed with a 0.2 second period, I expect each pass of the loop to read about 8 samples or 2 samples per sensor.  Instead, I get hundreds each passage.  It's like reading has substituted the sampling frequency specified in the task of the unit.  I absolutely need data to be material to the rhythm.

    Where have I lost?

    Thanks Adnan,

    I changed your example I selected 'Strain gage' entry analog and then lowered the minimum and maximum thresholds to +-1-2.  What happens is that each other in the loop, I 2048 samples or zero samples.  The display flashes a whole line and then it clears any other past.

    In response to your second post, I understand that the loop cannot run quite right that I select.  I think that, but at a sampling frequency of 10 Hz, I have to sleep on the software side for nearly a minute before I built 2 K samples.

    I played with the frequency of sampling, assigning to various values from 0.1 to 10000Hz.  The behavior is the same until I approach the high rates where available samples remains to 2048-4096 sometimes, the display becomes continuous.

    Ahhh, Darn.  Yet another search was this link that points to the root of my confusion.  The 9237 can taste arbitrary rates using its internal clock.  Duoh!  I wish that the pilots are smart enough to warn you if there is a discrepancy between the selected sampling rate and capabilities of the device

  • HAVE sampling frequency is divided by the number of channels + 1 for simulated ENET-9213, WLS-9213 and USB-9213

    Hello

    In the code in the example attached, I create a task with a single channel of AI.

    I get the maximum sampling frequency using DAQmxGetDevAIMaxSingleChanRate (or DAQmxGetDevAIMaxMultiChanRate), both return the same value of 1351 s/s.

    When I try to configure the sample calendar using DAQmxCfgSampClkTiming at the maximum sampling frequency clock he does not accept the rate and returns the following error. Note that the error message shows 2 channels, even if only a channel has been added.

    OUTPUT:
    DAQmx error:
    Sampling frequency is greater than the maximum sampling frequency for the number of specified channels.
    Reduce the sampling frequency or the number of channels. The increase in the conversion rate or
    reduce the time of the sample can also mitigate the problem, if you define one of them.
    Number of channels: 2
    Sampling rate: 1.351351e3
    Maximum sampling frequency: 675.675676

    Why the device driver thinks I have 2 channels in the task, when a channel has been added?

    The MathWorks

    Hello w,

    By default, the ENET/WLS/USB-9213 in NOR-DAQmx module has the AI. AutoZeroMode the value of the DAQmx_Val_EverySample property. This causes NOR-DAQmx acquire the channel of the internal path of the unit (_aignd_vs_aignd) on each sample to return more specific measures, even if the operating temperature of the device moves over time. If you need the sampling frequencies higher than this allows, you can call DAQmxSetAIAutoZeroMode(..., DAQmx_Val_Once) (who acquires the formatting string when you start the task) or DAQmxSetAIAutoZeroMode(..., DAQmx_Val_None) (which disables the setting entirely).

    Note that for measures by thermocouple with cold junction compensation sensor of the 9213 NOR, NOR-DAQmx acquires channel built-in CJC (_cjtemp) on each sample as well, for the same reason.

  • buterworth sampling frequency filter

    Dear friends, hope it's a good day

    I was wondering what is the best sampling frequency if the buterworth filter configured to. I know that some of you suggest trying different values from 1000, but I ask just for the guys in your experience.

    Thank you very much.

    Bill David,

    It must be set to the sample rate of the data that you are breast-feeding to the filter. If you buy data from an analog to digital converter, use the sampling frequency of the converter.

    I think that the default is to assume that each element of the input array is acquired to 1 second after the previous element.

  • Audition 3.0 how to disable ASIO and the default Sample Rate recording?

    Hi people,

    New here, but I hope someone can help me with a few questions, I'll have with Audition 3.

    Firstly, some background questions.

    I use hearing parallel to a broadcast audio broadcast program called SpotOn,

    This software requires that I run the sound card, a RME Madiface XT in 48 k mode, and that all the outputs that it uses are defined as WDM Windows so that the windows kernel mixer can control them.

    This means that when I use the hearing at the same time, I have to configure it to use the "Audition 3.0 Windows Audio" driver to stop him from taking control of the sound card directly and change setting which prevent SpotOn to see its output.

    The problems I encounter are that hearing itself seems to randomly change mode in the edit window ASIO driver, I suspect that this happens when I import audio data from a key which is from 44.1 to modify for use in SpotOn. This often seems to not only make the outputs of the card its invisible to the windows kernel mixer but also change the sampling frequency of 44.1 sound card and stops work SpotOn.

    The second question I have is that the sampling frequency of default record when I record in edit mode is always 44.1 and if used it again change the map sound 44.1 and causes the same problems, I'd be very keen to know how to change this default to be 48 k if possible.

    Then.

    What I ultimatly looking is...

    1. a way to disable the ASIO drivers in hearing so that it is not only this option is available, and cannot use the Audition 3.0 Windows Sound Drivers.

    2. a way to make the sampling rate 48 k to stop people choosing 44.1 mistakenly when saving default record.

    Any help or advice that anyone can give would be much appreciated.

    Thanks in advance for your comments

    What other pilots ASIO sees your installation of 3 AA? If it's the Madiface one and you use only WDM drivers you can just uninstall the ASIO RME driver?

  • Sampling frequency do not match

    I'm incredibly confused and a little frustrated, I hope someone can help me.

    Somehow, I got it work before. 192000 Hz at the hearing. No amount of fiddling with settings, reboot, or others can get me higher than 96000. 96000 works that if I go down the Apple Midi configuration to 96000, which makes sense, as suggests the error message it must be the same as Apple Midi. How is it, I can't Audition to save to 192000 when I put in configuration 192000 noon Apple?

    If I uncheck "attempt to force material to document sampling frequency" "Sampling rate" menu does not go higher than 96000, same Apple Midi Setup is set to 1920000. For fun here's a screenshot of the Audio channel mapping.

    No problem.  Let's take a step back and go through some basics.

    digital recording of sampling rate determines the highest frequency that can be reproduced.  A 44 100 sampling rate corresponds to a higher frequency of 22 050 Hz which is comfortably above the highest frequency even the best human ear can capture.  (Theorem of Nyquist Google if you are interested to know why.  This frequency is also higher than what most of the microphones can pick up and most of the speakers can reproduce.

    There are some who claim they can hear the difference in the higher sampling rates but certainly, I don't pretend to be one of them - and I have yet to see a blind man good test that could confirm.  In addition, some say that some special effects would be preferable to a larger "resolution."  Again, I'm skeptical, but maybe there could be some 3rd party plug-ins designed to work that way.

    That said, if it's for the video, you can work at 48, 000Hz, not for the quality but because it's a video standard.  FYI, it's to do with pair it with some video frequencies,

    Then, little depth.  This determines the available dynamic range.  24-bit has become somewhat of a standard record in common in the distribution of 16 bits.  For simple voice, you don't need 24 bits of dynamic range, but if you can't set to 16 bits is not a problem.  Hearing (and many other editors to work internally to the point 32, but floating because it protects you from distortion if you leave the creep too high levels when editing.  However, hearing handles it for you, and you only need to set your inputs and outputs according to the needs. In your case, that this is starting to sound like 48 000 / 24, but as you will be video and.what your default mic.

  • How to acquire with NiScope at different sampling frequencies and lengths Records?

    I need to acquire the data of 2 channels of the NI PXI-5114 map two different sampling frequencies high, at the same time. Also, I put 2 different record length. Is this possible?

    I understand that 'Vertical' settings can be configured for individual chains because the function 'Vertical niScope Configure' has 'channels of entry with which we can assign the desired channel. But for horizontal settings such as "min sampling rate" and the record min length, I could not find such an option to specify the channel. Would it not common to both channels?

    I hope that the device is capable of simultaneous sampling and therefore channels can be configured individually to different sampling rate.

    Hi AJ_CS,

    Why do you have to be distinct from sampling frequencies on channels separated from the digitizer even?  What different sampling rate do you want?

    But for horizontal settings such as "min sampling rate" and the record min length, I could not find such an option to specify the channel. Would it not common to both channels?

    You do not have an option to configure the settings of hoirizontal on a channel by channel basis because this concept does not exist in the traditional sense of the use of a scope.  Compatible with the concept of IVI, an oscilloscope traditional benchtop will have only a button or a set of buttons for setting the parameters of synchronization of the unit.  There is therefore no horizontal configuration to separate channels on the scanners NOR.

    I hope that the device is capable of simultaneous sampling and therefore channels can be configured individually to different sampling rate.

    Similar to a traditional benchtop oscilloscpe, the device is capable of simultaneous sampling.  But as mentioned above, the channels can not be configured for different sampling frequencies high.

    However, you can ignore data that you think is not relevant.  For example, if you assign 100MS/s CH0 and CH1 to 50 MS/s, then you throw all other samples.

    Alternatively, you can use separate scanners (a channel on each digitizer) and configure them to taste at different rates.  You can set frequencies of sampling on scanners NOR separated and even synchronize them with TClk.

  • How to acquire the signal to very high sampling frequency

    Hello world

    My name is Luke Ho. I am trying to acquire the signal with Labview (Sthelescope). The signal comes from sensor acoustics, then filters and amplifiers to adapt to ADC rank (0 - 5V). Thus, the maximum frequency of the signal is 40 kHz.

    According to the Nyquist theorem, I sampled at least 80 Khz signal.

    Is there a sampling frequency devices like that? or y at - it another way of better? I used the Arduino before, but it was about 10 kHz.

    I need your advice.
    Thank you all and have a nice day.

  • AI PXI-6255 sampling frequency

    Hello

    We use a simulated PXI-6255 device and with the LabVIEW example, apparently, that we can achieve a sampling rate of 20 kHz to 50 channels without warnings or errors.

    The spec is the number max of 20 kHz channels must be approximately 38 channels (750000 / 20000).








     

    1.25 single channel of MECH. / s
    multi-channel of 750 ksps / s (aggregation)

    The simulation cannot not representative of the unit or the real PXI-6255 does support a higher rate that we expect?

    Hi jharris66,

    It is not a limitation of the driver to the sampling frequency, so a simulated device reports any error in this case.

    In this example, I think that the limit of 750 kHz comes to the multiplexer.  I don't expect to see the same error messages with the real device, but your accuracy will probably not to spec because not allowing enough time settling between the channels.

    The limit of 1.25 MHz is the maximum ADC sampling frequency.  You can probably exceed this number somewhat, but once you go too far beyond 1.25 MHz you will eventually receive a synchronization from the hardware error when the ADC cannot follow.

    Thus, the specification is still technically 750 kHz for channels multiple acquisitions.  You can probably run at a higher rate than this (even on real hardware), but I wouldn't say that it is supported.

    Best regards

  • Xincrement is not agree with sampling frequency

    I use two PXI-5114 scanners that are being synchronized. I am taking 5 seconds worth of data.  I have = 1e3 sample rate and record length = 5e3. I get only about 1.3 seconds worth of data.  I looked at the actual length of the record and the actual sampling frequency outputs and they said the same thing as the façade made. I looked at and then the info out of the Cluster.vi of Fetch NiScope Multi Wfm and he had the same record length, but the value of Xincrement is 262e-6. This fits with what I get.  Any ideas?

    Thanks in advance.

    Hi AT1,.

    Thanks for posting. What you see, this due to the fact that the minimum sampling rate of the PXI-5114 is 3.81 kech. / s. The digitizer will force any value less than 3.81 kech. / s up to this value, so a record of 5000 samples take 1.31 seconds to acquire. If you are looking to acquire 5 seconds worth of data, I recommend to increase the length of record about 19 050 samples, which should be about 5 seconds worth of data. Let me know if this would work for your application.

  • limited on PCI-6052E sampling frequency

    I'm trying to measure with two channels with a PC containing a NI PCI-6052E card that is capable of 333KS/s on LabView 8.2. With two channels each channel must be able to 333KS/s / 2 = 166.5KS / s. everytime I try to set the sampling frequency above 94339 Hz I the following warning and the vi no longer works.

    WARNING 200012 occurred DAQmx start Task.vi:1
    Possible reasons:
    Clock speed specified is greater than the maximum ADC conversion rate. ADC invaded errors are likely.

    If I place a similar task in the Measument and Automation Explorer and I can easily make two channels measures to 160kHz without error. Above 166kHz I start getting the same caveat (200012). The code that I use calls first DAQmx create Channel.vi, then DAQmx Timing.vi and finally DAQmx start Task.vi. Everything works fine and I did measuements, but I can't rise above 94339 Hz sampling rate even if it should be possible.

    I just looked and I can't understand the issue here.

    Dear Voyn,

    I thank very you much for your message on our forum. If you create a task for a single channel, you can get a higher sampling rate? Are you able to reproduce the same problem with an example from the finder example? Go to hardware to go end tab selected and output-DAQmx online-online-online-online Acq Cont voltage analog measures & chart voltage-Int Clk.vi

    You will need to provide the model of your device. You can also look in the sheet/manual to see what the real supported sampling rates. Some devices have limited rates.

  • How to specify the sampling frequency? Must use "measurement &amp; Automation Explorer '?

    I use to measure the input current analog OR cDAQ-9171 (chassis only location USB) and NOR-9207. I have 2010 NOR-installed DAQmx and LabVIEW.

    How can I specify the sampling frequency?

    If I use M & A Explorer to create the task, I can specify the flow rate (Hz) on the Configuration tab-> sync settings.

    For the acquisition of data NOR, it is mandatory to use M & A exploring?

    If I don't want to use M & A Explorer, how can I specify the rate (Hz)?

    Hello

    You can specify the sampling frequency with "DAQmx Timing.vi" located in the function palette DAQmx (read context-sensitive help on how to use wisely).

    You do not have to use M & A exploring (MAX) to create a task.

    A simple and quick way is to use DAQ Assistant (same configuration as in MAX) to configure your measurement.

    Another is to use blocks of DAQmx function to manually build your application code.

    In my experience Assistant DAQ is ideal for simple tasks (one measure), with regard to the more complex measures (synchronized the analog and digital inputs).

    I tend to use function blocks because they give you more freedom about code execution.

    Note: You can also build DAQmx code from a wizard configured DAQ task.
