Incorrect value for analog output USB-6008. Cannot not out more than 3V

• Rate analog output USB-6008

  Hello

  I just started using an NI USB-6008 box. At this point, I don't need to fill all the specific tasks other than learning to use the device. I used a fair bit of LabVIEW but never with this kind of material, and I would like to help to understand it please.

  In particular, I have attached a VI in which I try to get an analog signal through the USB-6008 and read again (also with the USB-6008 - I wired the pins together). However, I do not understand what is happening when I run this VI. I expect the output a sine signal of 10 Hz for 1 second, 0.1 seconds record and see 1 full cycle of the sine wave. In practice, I read about 10 cycles and constant tension then. Presummably, this means that either the reading continues for more than 0.1 second, otherwise the output signal is more than 10 Hz.

  I also tried to use the related calendar DAQmx screws with the output pin to try to adjust the output rate (samples/s) but everything that I've tried return errors. I also tried to open some examples NOR, but these errors returned as well and I still just try things on mine.

  Did I miss something obvious here, but any help would be appreciated!

  Edit: I had to update this post & attached VI I had made mistakes. The default values on the front panel show what I see after the execution of the VI.

  Orbital Hi,

  As far as I know, you will need to use the DAQmx Read and VIs write in loops and functions of synchronization to determine data rates you want.

  I also did a quick search and found a white paper which you may find useful: http://www.ni.com/white-paper/9541/en/

• Input/output USB 6008 test failure

  OK I am posting this for the third time, but whenever I go back to the home page of the forum, I'm not able to find my post. If by chance I created duplicates than apologies.

  IAM in train to test the USB-6008 case I just got and decided to hang the analog of the analog inputs and see using labview VI.the wiring was done as:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/USB%206008%20wiring_zpss2b7hql9.jpg

  the problem is that the labview VI did nothing, so I go to NI Max and try to see in test panels. But I get 1.4V constantly my same analog input value when I'm changing my analog value:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AIO%20screenshot_zps9beiimbj.PNG

  the analog output works very well since I plugged it to my multimeter and I can see the tension that I see on this Panel of test:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/AO0%20screenshot_zpsqpei37bw.PNG

  I created an entry/exit of the tasks; screenshots of them are:

  http://i284.Photobucket.com/albums/ll5/bigdawg6/task_ao_zpsykmvczew.PNG

  http://i284.Photobucket.com/albums/ll5/bigdawg6/task_ai_zpsix5se9yg.PNG

  I am quite frustrated with all this since I'm unable to access my actaul draft. I know that 1.4 V value is from the device itself; as in the manual it says 'internal resistance divider can cause the Terminal to float at about 1.4 V when the analog input terminal is configured as a CSR', but the funny thing is that I use it in differential mode so I don't know what to do and any help is appreciated.

  BTW, I did a google search and there are other tutorials onlune who seem to do exactly what I do and they seem to work very well; so I don't know what else to do.

  Please don't host images on some odd third-party site. Attach them to your message.

  I don't understand what you've done. The 6009 can produce only a signal of CSR in order to set up the differential input makes no sense. If you want to measure something different, try a simple battery.

• AO. MaxRate, AO. MinRate, AO. Properties of voltage. RNGs for hardware DAQ USB-6008

  Hello

  in one of my report, I use the AO. Property of Voltage.Rngs to see if the selected DAQ card takes in charge the application voltage range. This works very well for my PCMCIA card as well as a PCI card. Now run the same VI with a USB-6008 device, this property gives all the return values. In addition, the report of AO.max.rate and AO.min.rate of the '0', the output is-200197 error properties. I use DAQmx as it is supposed to support the same functions for all DAQmx devices. Can someone please tell me what wrong here and how can I get around this?

  Best regards

  Gabs

  AO.min.rate and AO.max.rate are 0 and error-200197 back because the USB-6008 case supports the outputs analog hardware timed.  The description of error is "device does not support this property."  There is an entrance to the knowledge base for this question.

  By selecting 'Use Waveform' uses the synchronization of the sample clock.  The waveform data type specifies a delta t, which is used to set the sample clock frequency.  It is not supported on the box USB-6008.  You shouldn't set your calendar of sample type or explicitly assign the "On Demand".

  The DAQmx driver supports hundreds of different devices.  Not all combinations of properties are valid for all devices.

• Simple examples of analog output USB-6343

  I've tried passing by 'find' examples and does not know how to find what I want.

  I'm doing a simple analog output on a USB-6343.  Examples of waveforms say they work with the USB-6343, but I really don't want a waveform, just analog of output does not exceed 10 Hz speed of renewal.  Some of the more simple examples show that they work with the pcie-6343 but do not list USB-6343.

  I worked with USB-6009 in the past, but when I try to use an analog output task that uses 1 sample on request, I get the error "not buffered operations clocked by the hardware are not supported for device and channel type.»  Set the size of greater than 0 buffer, do not set up the timing of the sample clock or the value Type of sample On Demand time"

  I tried samples N, 100 samples to write to 10 Hz - the same error.  Samples of continuous - same error.  1-sample - timed HW - same error.

  There is a series of examples of I/O for the X series?  Is it possible to search the device examples rather than go through all the examples and by checking the list of devices individually?

  Is 'size of the buffer' the 'writing samples"in MAX?

  After contacting the support I was provided with the names of the more simple examples for analog i/o:

  Analog output-Gen power Update.vi

  Analog Input-Acq & chart voltage-Int Clk.vi

  They are found in the getting started screen of

  Click 'Find examples' near the lower right corner

  Filter the results to material by clicking on the menu drop down for the material in the lower left corner and selecting USB-6343 (only connected equipment will be displayed)

  Don't forget to check the box "limit results to material" below.

  In the center pane, double-click 'Material Input and Output'

  Double-click DAQmx

  Path for the analog input - double-click Acq & chart analog measures - double click on tension - tension-Int Clk.vi

  Double click on analog generation - double click on Power - Gen Update.vi of analog channel output voltage

  The examples are for the single data point.  Samples and exit multiples are produced by putting the writing or reading VI inside a loop.  The beginning and the clear functions should be out of the loop.

  Additional information, I need technical support was how material-filter results and identification of more simple examples which were not obvious from the examples of names.

• Population of list for the NI USB-6008 channel

  Hello

  I use labview version 2011. I have worked with USB 6008 for two months, but I encountered an error constantly even if I restart or shutdown of the PC for a while. I connected to my channel 6008 AI0 asensor and DAQ Assistant is not populating the available analog channels. Please someone help. Since it worked fine for a month, but not today.

  History was end I solved my problem after seeing the "Error in the knowledge base" pecautions on the site of NOR. Now the help data acquisition work.

  But I wonder how MAX data are linked with these DAQ contest. Some can clear me how MAX is related with all these functions of time real Labview.

  By the way, I'm using labview for two months.

  Thank you very much.

• How to structure the DMA buffer for SMU 6341 DAQ card for analog output with different frequencies on each channel

  I use the outgoing/incoming analog DDK with the DAQ 6341 SMU map.

  The examples, for example aoex5, show a single timer (method outTimerHelper::loadUI), but the example shows the DMA loaded with same size of vector data.

  There is a comment in the outTimerHelper:call rogramUpdateCount, which implies that memory sizes different pad per channel can be used.

  (the comment is: switching between the sizes of the various buffers is not used)

  Nobody knows what should be the format the DMA buffer for data from multiple channels with different frequencies?

  For example, we want a0 with a sinusoid at 1 kHz and a1 with a sine wave of 1.5 Khz.  What looks like the DMA buffer?

  With the same frequency for each channel, the data are interleaved, for example (ao0 #0, ao1 #0; ao0 ao1 #1, #1,...), but when the frequencies for each channel is different, what the stamp looks like?

  Hello Kenstern,

  Data are always intertwined since each card has only a single timing for each subsystem engine.

  To AO, you must specify the number of samples that will be released to the AO. You also specify the number of channels. Because he didn't is that a single engine timing for AO, each AO will be channel will be updated at the same time to update clock tick. Data will be interlaced exactly as shown in the example because each channel AO needs output at each tick of the clock to update. The data itself can change depending on the frequency you want to copy.

  In your example, you must come with an update rate that works for the two waveforms (sine waves of 1 and 1.5 KHz). To get a good representation of a sine wave, you need to update more than 10 x faster than your fastest frequency... I would recommend x 100 if possible.

  Update frequency: 150 KHz

  Channels: 2

  Then create you stamps that include complete cycles of each wave you want to produce based on the frequency of update. These buffers must also be of the same size.

  Buffer 1: Contains data for the sine wave of 1 KHz, 300 points 2 cycles of sine wave

  Buffer 2: Contains data for the sine wave of 1.5 KHz, 300 points, 3 cycles of sine wave

  You can Interleave them as before. When the data are performed through the ADC, they are out different sine waves, even if the AO channels are updated at the same speed.

• Amplification of Type K Thermocouple for playback with USB 6008 at high temperature

  I'm looking to amplify a K type thermocouple, so that the signal can be read with a bit of precision by a USB-6008. I watched the AD595 chip, but it indicates a maximum useful temperature of 100 ° C and I'll need to read up to 700 C.

  Is there another amplifier chip that would work up to this temperature, or should I resign me to use the unamplified signal and get a very inaccurate (~ 30/division) the temperature reading?

  The AD595 has a range of-200 C to 1250 C, here is the data sheet:

• Issues of analog input DAQ-6008, voltage not zero to pin when you are offline

  I use the 6008 NOR-DAQ to produce a series of tensions and then read a sense resistor using the analog input (CSR). I noticed that my analog input gives me 1.3 V, when I probe it (compared to the mass of the device), when it is completely disconnected. This changes the reading to give me a different measure of sense than expected resistance.

  Why is my pin for analog input non-zero? Any help would be appreciated. Thank you!

  The 1.3 V is expected. The USB-6008-and-6009 case have the strangest input of the world circuit. The input impedance is approximately 144000 ohms terminated in 1.4 V. check the document User Guide and specifications.

• Predefined values for LOADING, DONE, XMLHttpRequest etc. appear not defined under the ripple

  I use XMLHttpRequest to call a REST services.

  When the test is under Mozilla and Chrome, everything works fine.

  Although, when I activated the ripple under Chrome it has stopped working. After some debugging I discovered that in the switch/case statement, where I do something like...

  switch (this.readyState) {
   case XMLHttpRequest.DONE: ... some code here ... break;
  }
  

  ... the 'case' did not get fired.

  Further examination has determined that all the XMLHttpRequest.* values are undefined is the reason why my code no longer works.

  Q: why the values if readyState XMLHttpRequest, not well-defined, becomes indefinite under ripple?

  Are there solutions to this problem, other than the use of simple numbers like 1, 2, 3, 4 or set values for myself.

  Please try with 0.9.4, which is what I am running.
