• Acquiring bipolar signals NI DAQ USB 6009

  Hello

  The NI DAQ USB 6009 case is capable of acquiring biploar waveform?  I have a signal generator that provides a 0.5V wave triangular amplitude in the NI DAQ USB 6009.  The NOR-DAQ is connected to LABView and acquire signals using the LabVIEW express vi. The waveform that appears is unipolar.  Terminal configuration is set to differential. Is the waveform which is seen. Thank you. Mary

  Hi Tupaj,

  See a voltage floating as this can sometimes be the result of a measure badly grounded.  It would be useful, like Dennis, to know how you have this wired up.  Please take a look at this guide to make sure that the device is properly connected to Earth:

  Field wiring and analog noise - http://www.ni.com/white-paper/3344/en

  In addition, information about the configuration of your software are also important.  Here's an example of how implementing a fundamental mission of analog input for your 6009:

  Video installation instructions - http://www.ni.com/swf/devzone/ai/

  The example Finder has also several screws that already do it for you.  If you work in 2012 before LabVIEW, look for Acq Cont & chart voltage-Int of the Clk.vi in the Finder of the example.  LabVIEW 2012 will have a similar named VI voltage - Software-Timed Input.vi.

• BSOD when base closing program NI DAQ USB-6009

  So, as the title suggests, I get the BSOD error code: MULTIPLE_IRP_COMPLETE_REQUESTS when I close the basic example of the analog input for NI USB-6009. Someone at - he lived this before? My specs are:

  -LV version 15.0 32 bits (developing 64-bit installation to solve a problem without a report, do not know if this will help here as well)

  -Win7 Ultimate x 64 (SP1)

  -Alienware M17x R3

  -Core i7-2860QM

  -12 GB OF DDR3 RAM

  Any ideas on what could be the cause?

  Does happen with particular vi or exe or anyone, including max and daq assistant? If it was built on this machine? Try to force recompile all (Ctrl + Shift + click the button run.

  I can hardly imagine what can be encoded in simple artificial intelligence causes of BSOD. I'd say it's machine problem. Something is not installed correctly. Is - this change help USB? Card mother does a USB 2.0?

• Using the DAQ USB-6009 meter and an analog input voltage at the same time.

  Hello

  Currently, I'm reading the two channels of voltage with the USB-6009. It happens that one of the channels is the output of a digital coder, and it would be much easier to use it directly to the PFIO entry that is defined as a counter. The problem I am facing right now, it's that I can't use the DAQ Assistant to use the analog voltage to a channel and the digital channel counter at the same time. Once I put the DAQ Assistant to read the input from analogue voltage, I won't be able to add analog inputs. And as I put the DAQ Assistant to use the PFIO as a counter, I can add more entries to read analog voltage is.

  I wonder if it is possible to solve this problem using the lower level data blocks? Another solution would be to read two channels in analog input voltage and that the use of Matlab to process data resulting from it, since I was not able to do the counting to work simultaneously with the acquisition in Labview to impulses.

  Hope you guys can help out me.

  Thanks in advance.

  Using a simple wizard of DAQ is incorrect. You need one to acquire analog inputs and one for the meter.

• 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.

• Port USB USB-6009 bug

  Hello

  I would ask for advice. This is the scenario in a few words:

  We have a new project already written in LabView to control a mass of a machine from K - Ar spectrometer and record two analog channels of an NI USB-6009 device data. Rate is the maximum: 24 kHz per channel.

  After deployment, we started to get a DAQmx driver strange error, but only when we used a certain port on a DELL laptop (this port was a 2.0, the other SS 3.0). USB ports did not create this error. After several days, when we realized, the error is not in our LabView code, we found this conversation in the forum:

  http://forums.NI.com/T5/Multifunction-DAQ/USB-6009-overflow-error-on-continuous-mode-after-restart-o...

  We believe that it would be strange to tell the client that "Please do not use this device ON this port, because it's a little bug...". ", then

  We were very happy, because this DAQmx property through the property node solved the error of USB port (see attachment file).

  However, a few days ago, we got an unexpected behavior: our program during a mode over DAQ completed the acquisition of a few seconds earlier, then he should have done. There was no signal error, but only this strange behavior, like in the "task done? VI DAQmx reported "too early."

  Since this 'error', we could not reproduce it yet (so far), we have used the program several times without problems via this "slow" USB 2.0 laptop port.

  Well, I'm always interested in a definitive solution of OR to fix this in their products and in the DAQmx driver. I heard many colleagues that they run into this bug of USB port several times when they use NI HWs, and this problem is very annoying. I know that the solution usually easy: plug the device into a different port. But I think that these materials should run flawlessly on the USB ports on all THE...

  Hi man,

  If you found your own workaround by plugging the USB module to another USB port.

  You said the accures only mistake on the special USB computer ports. This can be caused by an internal hub used in the computer. USB hubs may cause difficulties with hardware OR.

  Do you have other questions?

• Why LabVIEW 2012 does not support USB-6009?

  Hi all

  I recently installed LabVIEW 2012 and DAQmx 9.6 (and also tried with latest version) in my PC with Windows 7. I have the version of Explorer 5.4 measure and automation. I'm working with hardware DAQ USB 6009. Everything seems compatible, but when I try to post data acquisition, it fails. However, I used to use this device (since I bought it last year) with the other PC that has the Windows XP operating system and the older version of LabVIEW 8.5.

  What can I do with LabVIEW 2012 is a message "a 88302 error has occurred." and "This could be an internal error."

  If someone has an idea to solve the problem, please let me know.

  devkotaj

  Hi devkotaj,

  The USB-6009 device should work perfectly on Windows 7 with the software you have listed. This looks like a problem of configuraiton of material for me.

  What are you trying to do when you receive the error 88302? This error usually indicates a corrupt DAQmx driver, which may result from the installation of several DAQmx versions on the same machine. Have you tried repairing your installation DAQmx? I could uninstall DAQmx from the Control Panel before installing the latest driver. You can see our procedure to reinstall or uninstall recommenedd here.

  I hope this helps!

  I use a card DAQ USB-6009 to read the signal from 3 channels. at the same time, I want to read a TTL trigger and genearte a TTL trigger or a waveform square with a delay of 4 seconds.

  I'm reading the trigger and then write with "wait" function in my loop. but I find that there is a bug with the writing of the matrix. I can read the writing the trigger with single channel, but not with multiple channels.

  Here's the EIS. Please help me with the file of multiple channels to see why it does not work.

• Simulate signals wired to the DAQ assistant for USB-6009 device

  Hello

  I'm trying to send a signal to the DAQ Assistant Express VI.  I watched the movie "Generating a Signal" on the Web site of NOR (www.ni.com/academic/students/learnlabview/generate.htm) and I have my Signal simulate connected directly on the DAQ Assistant, as shown in this film.  In my case, the DAQ Assistant sends the signal to a device USB-6009.

  However, I received this message:

  Error-200077 occurred to the DAQ Assistant
  Possible reasons:

  Requested value is not supported for this property value. The value of the property may be invalid because it is in conflict with another property.

  Property: SampTimingType
  asked the value: Sample clock
  You select: On-demand

  If I select 'On Demand' in my DAQ assistant and run the vi everything works beautifully.  However, I need my DAQ assistant to be configured to generate a waveform AC continuous, not output a single alternating current rippling.

  What happens here?  I did not have this problem before on other devices of NOR. I am using LABView 2010.

  Please answer.

  Thank you.

• OR USB-6009 daq sample following loss, while the loop iteration

  Hello

  I am trying to acquire and display data measured from a DAQ NI USB-6009 material using Labview 2015. I am using the wizard daq defined for the differential mode and n samples with the sample rate and the total number of samples registration by the user. My problem is that when the specified amount of samples is acquired and the while loop continues to the next iteration, some samples are removed (I know because I tested it acquire a wave of fishing and there is a noticeable artifact in the signal at times where the while loops - I downloaded a file showing this artifact in a wave of fishing that was recorded with a sample rate of 1000 Hz 500 samples of recording each) iteration which means that the artifact occurs every half second).

  I think that this can be corrected by simply taking off the while loop daq assistant and specifying the number of samples you want the entire test to acquire. However, I would like to see the signal in a graph as its achievements and the daq can acquire data indefinitely until the user presses the stop which, to my knowledge, it would take a while looping. I downloaded my vi for reference, and any help would be greatly appreciated!

  Set your Acqisition Mode on "samples continues."

  N samples: reads the desired number of samples and stops.  Will read once again what DAQ Assistant is represented.  In other words, that there is a gap of time between readings.

  Continuous samples: data acquisition just constantly reads the data.  The DAQ Assistant just gets the number of requested samples and data acquisition keeps just read and store it in the buffer.

• About precision of analog input of acquisition of data USB-6009

  Hello

  I have a problem where I'm reading a temperature signal (10mV / ° c) using the USB-6009 case, but a problem of accuracy of the input signal of the DAQ hardware.  The temperature at room temperature reads at a constant 230mV (23degC) using a multimeter device, but with the DAQ hardware, I see the signal bouncing around to 25mV, + effects greatly my work.

  I was hoping someone might have a solution to this as my brief search forums nothing have mounted.  Is there a way to average this broad band to the extent of the input signal or from resovle anyway?

• USB-6009 vs Non-traditional (e.g. 6001, 6002) Multifunction DAQ

  I use a USB-6009 in my console application and when I went to buy another, I noticed that it is classified as a "Legacy" product Nobody knows how it's performace compares with the non-traditional low-cost multifunction Renault. as the 6001 or 6002? In particular, I'm more interested and noise, as well as the overall accuracy of the analog inputs.

  As an aside, the 6001 or 6002 allows you to adjust the range of entries analog to nothing else than the full scale +/-10V? The 6009 allows you to go up to +/-1V to achieve the best accuracy that I find useful.

  I would be happy to compare me the specs, but sheets of these parts are not very complete.

  Thank you.

  Just go through the specifications in the product pages and you will get the answers you want.  If you need more information, go dig in the specification documents, which are related in the product pages.

  I'm not in the specification of precision, but the Renault 'basic' have only the 1 range.

• Typical values for the external resistance of pull-up on a line of output digital NI USB 6009?

  Hi all

  I use a digital line on a USB-6009 to control a SSR by the attached diagram (in the manual USB 6009).  I don't have access to a variable resistor or box of 10 years, so I'm hoping to get a good approximate estimate for the value of Re.  When I connect the CRDD at a 5V supply, it shoots 8.2mADC when closed.

  Any suggestions?  Is there any other information I can post for help with the guestimations?

  Thank you!

  I have found an old box of decade Heathkit and understand the degree of correct resistance 100 ohms.
