• 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!

• 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!

• 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...

• Outputs analog USB-6211 won't go below 3.375V

  I use a 6211 to pulse output 0 - 5V outputs analog using an external clock as a trigger, and after successfully using the system for a while I finished with a question where none of the channels AO out lower voltages at 3.375V. My current theory is that I can have exceeded the current 2mA max output, but I don't know how, which would result in what seems to be a permanent tension.

  I have reset the device and tried using other computers, but the problem remains. I ran the diagnostic utility and it fails part AO when it tries to output 0V and reads the 3V but he gave no further information. All other parts of the diagnosis are very good.

  Any help would be appreciated, I'm a little stuck on my diagnosis.

• rate real output analog OR-6351

  Hello

  I am trying to create a generator of arbitrary signals on both channels DAC on a NOR-6351.

  Everything works fine - with the exception of the fact that I'm not sure what is the real rate of analog output.

  This is quite crucial for me, I have calculate my wave based on Fourier transformation fast discrete - to get the correct frequency, so it is important to know the rate of real output.

  The card has a rate of update AO 2.86MS / s,. The property timing - real sample clock frequency product also these 2.86 MHz.

  When I then try to use the same frequency to generate two analog outputs, it always tells me that it uses 2, 86 MHz, even though the notebook loads says only he can produce 2 ms/s when using two channels.

  So my question is, how to determine the actual flow of outputs analog?

  And what is the rate of real output of the DAC?

  Concerning

  Jørgen

  I just had a scope attached, while generating a sine function at 300 kHz, the rate of 2.86MS / s.

  The scope read 300 kHz, which must mean that the DAC will actually to 2.86MS / s, otherwise the resulting waveform would have been to close to 200 kHz.

  I have this will mark it as resolved, although I have not yet crazy understand why it is able to output at this frequency.

• Producer consumer with inputs and outputs analog and digital

  Hello world

• How to trigger and outputs analog and digital Outout tasks begins on a counter to start?

  Hello

• FPGA output analog fastest? (RIO 9641)

  Hello world!

  I read only analog output have about 38 tics. clock 40 MHz (RIO 9641)
  My RIO gives me tics 107 = 112 - 5 analog outputs for the 1 iteration. If DAC cycle... The entire cycle takes (112 * 160 * 25th-9) for DAC 107 * 160 * 25th-9 = 428e-3 s always takes DAC, and I need more quickly.
  How to set up outputs analog faster or rebuild program?

  I need the fastest analog output, is it possible?

  Thanks for the help!

  

  

  Hi togoto,.

  Please let me know if I'm struggling to understand what you're trying to do, but the fastest, the analog output of the 9641 can update is 120 ticks by update.  Which is based on the specification of the material on page 44 of the User Guide and the restriction that you touch.  Therefore, I don't think you'll be able to get it down to 40 ticks.

• 6361 versatile usb data acquisition does not automatically detect the SCXI chassis/accessories

  versatile usb data acquisition 6361 will detect automatically SCXI chassis and accessories?

  Hello kdCMC,

  As far as I know that the SCXI-1600 USB Module is able to auto-detect SCXI Modules.
  This is also mentioned on page 11 and 12 of the following SCXI to start document:
  http://www.NI.com/PDF/manuals/373236m.PDF

  All data (including USB-variants such as the NI USB-6361) have only a 68 pin shielded cable (IO) between the DAQ hardware and the SCXI chassis.
  This cable does not auto-detect opportunities since it basically just "transfers analog and digital signals" between SCXI chassis and DAQ hardware.

  Is there a specific document that created the confusion on this subject?

  Hi the prey,

  ·         What is the brand and model of the computer?

  You should check the settings of the computer BIOS (Basic Input\Output System) to boot from the CD/DVD. Check the manual or the support of the computer Web site for the same.

  Note: Be careful when you change the BIOS settings. The BIOS interface is designed for advanced users, and it is possible to change a setting that can prevent your computer from starting properly.

  Installation steps:

  APEX 5.0.1.00.06

  @apxrtins.sql SYSAUX SYSAUX TEMP/i /;

  First of all what you have installed 'Runtime Environment' for Oracle APEX 5.0 and 'Runtime Environment' has no GUI as in "Development Environment". 'Runtime environment' has GUI access only for applications deployed in it.

  Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/overview.htm#HTMIG366

  You need to convert "Runtime Environment" to "Development Environment".

  Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/listener.htm#HTMIG29457

  Are you using the correct installation procedure Oracle APEX and configuration ADR?

  Reference: https://docs.oracle.com/cd/E59726_01/install.50/e39144/listener.htm#HTMIG29143

  Second thing : when you use Oracle REST Data Services like Web listener option, there is no /apex but /ords. So, your connection APEX links will be:

  • http://localhost: 8080/ADR / (APEX development)
  • http://localhost: 8080/ADR/apex_admin (APEX Instance Administration)

  Third thing : on 404 - when setting up ADR 3.0 have you skipped configuration "PL/SQL gateway '? (This step refers to the configuration of Oracle APEX with ADR (APEX_PUBLIC_USER configuration) which is required for the operation of Oracle APEX with ADR)?

  Otherwise, you will run into the following error message:

  • Re: Re: ADR 3 404 error
  • Re: problem with ADR 3.0

  Also open your "ords.3.0.1.177.18.02" folder and run the "readme.html" file in a browser and go to the section "404 errors when Oracle configuration REMAINS Data Services" on the causes of 404.

  Finally , go through the following threads on the Oracle APEX installation and configuration ADR where talked to errors of detail in the course of setting up ADR and the means to solve them:

  • Installation of ADR after 5 APEX
  • Can't 5 Apex to work...
