• Difficult to use the outputs analog to generate a predetermined file

  Hey all,.

  I tried to produce a file predetermined to a 1 kHz on my USB 6343 Multifunction DAQ analog output channel.

  Here are the questions I have am experiencing:

  1: output file so fast my o'scope cannot even pick it up.

  2: when you try to stop the output it almost freezes.

  3: my graphical waveform data and the plot does not update with the data that have been read.

  If someone wants to tackle one or more of these questions, I would be very appreciatve.

  Thank you

  I tried to adjust the "DAQmx Configure Ouput buffer" but it really doesn't seem to have much effect. Do you think I should try a loop For to pick an amount predetermined points then output them quickly?

  It's weird.  So I don't generally need to use the function of output buffer configuration you have.  If you look at using the Subvi DAQmx Timing just after it, you will see the samples per channel will help determine the size of the buffer.  You might want to try do not use the function of buffer output set at all, not that I don't know if that will fix it or not.

• Integrate the outputs analog with analog inputs

  I have a program that displays 2 analog output waves and a separate program that captures the analog data through several materials of NEITHER. I need to integrate the program outputs analog in my analog input program.

  The program of analog output is fixed as "AO_Triggers_LowLevel.vi" and the analog input is fixed as "ExperimentDAQ.vi". When I try and integrate these programs I get 'error-200560 occurred at DAQmx waiting until the Done.vi' to my function to wait until it makes my task of analog input (background of the program). I think it is my mistake in the order that I'm wiring to the top of my son of error but I'm not sure. I watched several tutorials (Timing and synchronization features of DAQmx) but I'm totally stuck.

  Any suggestions are greatly appreciated. Thank you!

  I think I've fixed this problem. I extended my flat sequence structure to include the lines of task and error of my task outputs analog and things seem to work.  I'm still not sure about what caused my error and why it has solved the problem...

• can I connect the outputs analog of a DAQ configuration in series to have the highest voltage source?

  Hello guys,.

  My question is provided in the topic, you have an idea about that? your help is appreciated.

  ELA

  Hi Ela,

  For almost all devices supported by DAQmx, you can't. When all AO channels have the same motive, connecting them in series would be short the output channel on the ground, which is bad.

  However, there is one exception: the SCXI-1124 module has channel-to-channel isolation, which allows channels to be cascaded to output voltages: I can cascading the output voltage of an SCXI-1124 module?

  With channel-to-Earth isolated peripheral (such as NI 926 x or NI 623 x), you can cascade multiple devices together, but not multiple channels on the same device.

• Output analog, the USB-6009 case - can I use DAQmxWriteAnalogScalarF64?

  I just got a NI USB-6009 and I try to use the outputs analog simple.

  I'm running on a Mac, so I'll try to use the API OR-DAQmx Base 3.2 C (downloaded from here: http://joule.ni.com/nidu/cds/view/p/id/1078/lang/en).  This is the most recent version of NOR-DAQmxBase, I could find.

  I try to do continuous analog output on the 6009, which does not have a built-in clock.   I was hoping to do the sync software and just new output values when I want to.

  I can't get an output of database to work.  Other messages and the example of Windows files, (e.g., National Instruments/NOR-DAQmx Base/examples/ao/MultVoltUpates-SWTimed.c) it seems that the best thing to do would be to use the DAQmxWriteAnalogScalarF64 function.

  However, this is not in the Mac version of the C API of NIDAQmxBase.  There is actually an entry for this in the NIDAQmxBase.h file, but it is commented out.  Anyone know why?  Is it possible to use this function for the analog output on request on Mac?

  Thank you.

  I have NEITHER-DAQmx Base installed 3.2 on a 10.4.11 system.  One of the examples files 'genVoltage.c' calls DAQmxBaseWriteAnalogF64.  I was able to compile and run this example with a USB-6009.

  The DAQmxBaseWriteAnalogF64 function would work for you?

  My guess is that, since you can write a scalar value with DAQmxBaseWriteAnalogF64, DAQmxBaseWriteAnalogScalarF64 becomes superfluous.  The example provided with the installation shows how to write a unique value (i.e. scalar.).  I pasted the code of OR below.

  int main (int argc, char * argv [])

  {

  Task settings

  Int32 error = 0;

  TaskHandle taskHandle = 0;

  char errBuff [2048] = {'\0'};

  Channel settings

  Char [] = "Dev1/ao0" chan

  float64 min = 0.0;

  float64 max = 5.0;

  Sync settings

  uInt64 samplesPerChan = 1;

  Writing data parameters

  float64 data = 3.25;

  pointsWritten of Int32;

  float64 timeout = 10.0;

  DAQmxErrChk (DAQmxBaseCreateTask("",&taskHandle));

  DAQmxErrChk (DAQmxBaseCreateAOVoltageChan(taskHandle,chan,"",min,max,DAQmx_Val_Volts,));

  DAQmxErrChk (DAQmxBaseStartTask (taskHandle));

  DAQmxErrChk (DAQmxBaseWriteAnalogF64(taskHandle,samplesPerChan,0,timeout,DAQmx_Val_GroupByChannel,&data,&pointsWritten,));

  Error:

  If (DAQmxFailed (error))

  DAQmxBaseGetExtendedErrorInfo (errBuff, 2048);

  If (taskHandle! = 0) {}

  DAQmxBaseStopTask (taskHandle);

  DAQmxBaseClearTask (taskHandle);

  }

  If (DAQmxFailed (error))

  printf ("error in DAQmxBase: %s\n",errBuff); ")

  return 0;

  }

  Hope this helps!

• How can I change the configuration for the output channels analog on a PXI-6704?

  I can't seem to understand how to access the configuration of the channels to the outputs analog (channel 33 and 35) for PXI-6704.

  This piece of test equipment is out of tolerance and must be calibrated.

  I have followed the procedure of calibration http://www.ni.com/pdf/manuals/374081b.pdf, but am getting hung up on step 8, where it is said to repeat steps 4-7 when changing the _cal_ao_current_offset. I can't figure out how to open this channel because it is not listed as a physical channel for step 5.

  I'm using Labview 7.1

  Thank you

  Hello! What you need to do is to add 'Internal channels' to your list of channels, so you can choose the _cal_ao_current_offset or _cal_ao_voltage_offset.  This is done through the drop-down list channel right click and select "I/o name of screening...". ».  There will be a check box that says 'Internal channels' and will provide you with all available internal channels to enter your vi Create Channel.  I have attached some photos illustrating how to do. See you soon!

• How to synchronize the analog input and the output of two different USB data acquisition boards

  Hi all

  I have two tips very different USB NI USB 6008 case, which I use to acquire the data (analog input) and a USB of NI 9263 is a output analog only site I use to route a signal (in this case a square pulse). The reason why I use the outputs analog 6008 is because I need to deliver negative tension and need the full +/-10 v range.

  Looking at similar positions, I'm pretty sure that I can't use an external trigger or a common clock, I also tried to use the timed synchronization of the structures but no cigar.

  I'm including a quick vi I whipped showing how the jitters because of the lack of synchronization signal. The OD of the 9263 connects to AI in the 6008 in this example.

  I talked to a specialist in the phone and tols me that's not possible.

• How to control the two analog outputs at a time

  I'm new to LabVIEW and have some problems in DAQmx with control outputs analog multiple.

  I want to set up a platform using BNC-2110 and PCIe6363 to control two rotating mirrors. The problem that I can only give an output (AO0 or AO1) at a time and I really have no idea how revise my LabVIEW diagram to control two outputs at the same time I met. I tried to change the outputs and it keeps a mirror turning instead of the old. Could someone help me with my problem and I would really appreciate. This is my blocked diagram and front.

  

  

  Hi zrmaker,

  As mentioned by RavensFan, you should not create 2 analog outputs different tasks if you use AO0 AO1. To your façade > physical control or the channels > select the drop-down list of the control channel physical (s) > Browse > hold down the CTRL + select the AO0 and AO1 > Select OK. Once this is done, you will see that your control or the physical channels has the following input values: "Dev1 / ao0:1" which means that you will access to AO0 AO1.

  In regards to writing DAQmx, simply select Analog > multiple channels > samples multiple > 1 waveform (you should get the following: 1 d Analog Waveform NChan NSamp). Once done, you can just use table build to combine 2 different waveforms and plug in this table to DAQmx writing output. The first index will be the output for AO0 value and the other will be for AO1.

  You can check this link on how to read or write from several channels: http://digital.ni.com/public.nsf/allkb/0C1ADEF06A54AB2D862575040066FD51

• read the output of a path of analog output current voltage

  In DAQmx if you are unsure of the status of a digital output port, you can take a reading on this subject.  When I try this on an analog output, I get an error.  Is it possible to query the status of the output of an analog output?  I realize that I could follow the State with a variable, but a direct reading would be really handy.

  Hello, GIS.

  There is no way to read the output in the AO modules without wiring physically the signal to a module to HAVE.  You are able to use a variable to read the current value of the output, as you mentioned earlier.

  Channels AO multifunction boards, however, can be read through tasks of entry by rounting in-house channel to read ao vs aoground.

• Negative outputs analog of the PCI-6229

  I appreciate this question may seem a little primary for some of you, but I spent hours looking for an answer with no luck.

  I have a card from e/s NI PCI-6229 M series I want to use to order a proportional hydraulic valve. The valve in question takes input in the range from - 10v to + 10v, which fortunately is the flow of the IO card range.

  My question is this; in order to generate a negative voltage (-) through the valve, what I need to connect to the two terminals (AO0 and AO1) AO or can I connect to a single AO (AO0) and the ground terminal (ALWAYS)? Or to say it another way, can the material generate a lower voltage to ground thus creating a negative through the valve potential difference if one is ALWAYS used?

  Thank you very much.

  Hi James,

  My mistake because I thought you were using LabVIEW. In theory, you should still be able to set the output programmatically.

  This link from the site Web of The MathWorks shows how to vary the values of your analog output when someone was using a PCI device , so it can be useful.

  I think the block National Instruments analog output is likely to be also useful.

  Having not used the xPC Target before, it's hard to be sure if. I highly recommend using LabVIEW next time

  And yes I count not that you went on your wiring in the correct manner.

  Kind regards

• How stable is the long term outputs analog USB-6008?

  The USB-6008 datasheet do not specify the stability long term of the analog inputs and outputs.

  I'm looking for stability compared to the ambient temperature and time (several months to a year), mainly for the outputs or the D/A reference voltage.

  Is there any information available?

  Thank you.

  The precision specification takes into account the evolution both because of the temperature and duration (stable).  Thus, for the period of a year that we guarantee these specifications, which list you is correct.  However, apart from the period of one year since the calibration, this specification may be is more inaccurate.
