Bad drift with USB-6259 devices and acquisition of data PCI-6259

We have both a USB-6259 and PCI-6259 installed on a single computer, linked to a SBC-68, with Matlab and Toolbox of data Acquisiution.

For the purposes of test base, I wrote a script that generates a sinusoidal signal output based MATLAB, for a single DAC output.  I wired this single DAC output to two channels of ADC of entry.  For each sample output DAC, the script also takes a sample entry of ADC on each channel.

--> Ideally, if everything works correctly, after you run the script, I see two channels of input ADC vector.  Tracing of each channel should give me a nice sine wave in Matlab.

--> When I made trace data, here's what I get (see attachment).

-->, I looked at the DAC output with an oscilloscope, and the DC offset is very close to 0 (this indicates to me that the part of output DAC works very well).

Why is there this negative DC drift on two entries?

Forgive my lack of knowledge - I know the difference between the DIFF and CSR connections, but I don't know where is the 'setting' for DIFF/CSR (what is a button/switch on the USB-6259 case?  Is it a software control in the code?)

  • Communication problem between LabView and acquisition of data USB 6259

    I want to monitor a data USB-6259 acquisition using LabVIEW 8.6. However, when you try to create an explicit task (using the DAQ assistant) in order to acquire a signal, I get the message asked supported device found¨. I can see the USB-6259 under ¨Devices and interfaces¨ to the MAX, but when I try to import the configuration data for NOR-DAQmx 8.7.2 in MAX, I get the message ¨Can´t import file configData.nce.  File not found¨. I use NEITHER-DAQmx 8.7.2.  Any suggestions?

    Hi, Corneliu,

    This question could be generated due to a corruption of database of MAX. Here is a link to restore the database to the MAX.

  • Difficulty to read the instrument of series and acquisition of data simultaneously.

    Greetings,

    I have some trouble getting my VI read from my data acquisition and instrument of the series at the same time.  If I run the Subvi simultaneously (i.e. subANG runs in a window and subVEL is running in a second window) both return the correct values and behave as I expect.  However, if I call the Subvi in a society mother VI and try to run them both in the same loop structure subANG gets stuck and won't be reprobed with a signal change.

    I also tried to use a stacked sequence or plate to separate the execution of subVEL and subANG, but I still get no response to subANG.

    The point is is that, if I run Parent.VI in a single window and then creates a copy of subANG (call it '--copy' or other) and run it in a second window, Parent.VI behaves properly and will update the readings as they appear in '--copy '.

    I enclose 3 files.

    (1) subANG.VI - this bed an an inclinometer RS232 signal.  The signal is refreshed every 10ms or more.

    (2) subVEL.VI - this bed raw tension of a channel on the acquisition of data, calculates the average then that converts into a pressure difference and finally a speed based on the pressure and temperature inputs.

    (3) ParentVI.VI - they simply call and displays the Subvi

    My guess is that it's a buffer problem, but I am confused.  Someone out there in Labview Earth knows why this might be happening?  Suggestions welcom.

    It is not an instrument of series.  It is a UEI PowerDAq with their typical A/D and the cable.

    I found away to make it work by placing subANG and subVEL in some time different loops side by side in ParentVI.

    Hello
    I have a lot of problems to install usb flash drives as pnp devices. It should install automatically as it did on my desktop and other mobile colleagues.

  • Interruption USB Raw: flow of data between USB Raw Device and Labview!

    I do the USB communication between device (Microcontroller) Labview and USB RAW. I did all the things like the raw driver OR USB and I am able to get the 8 bytes using getusbinterrupt.vi, but my application requires continuous data transfer between pc and microcontroller, inorder to achieve that I put continuous loop in the microcontroller, so it transfers the data of continuos on pc, (in this case e.g.0 to 255 and again from 0 to 255 and so on.) , but I'm not able to get increment of 1 as written in my program, instead of that I'm getting increment of 5 to 10... is it because Microcintroller is very fast as my pc? If so how can I get continuous data without breaks...

    I enclose... graphic instant with output vi this jump of the variable data... I run my vi continuously on mode...

    Like, I would also like to write to the device with labview, can you also suggest for this also? I read messages like:

    Run a quick code continuous mode is completely unnecessary.

    Laptop Dell Vostro 3700, Windows 7/32, Laserjet 4000, connected via the USB interface cable / parallel on USB001. Interface drivers and printer installed automatically after starting the update of Windows PC.

    Single document print OK.

    Document of several pages: printer data LED flashes then REMAINS ON permanently. Printed front page sometimes, sometimes not.

    After some time, box status Control Panel/print poster printer fault and a yellow exclamation point appears on the printer icon.

    Same printer connected via a parallel cable that is normal for old PC Windows 2000 print OK.

    Help, please!

    SOLUTION FOUND!

    A SOLUTION THAT WORKS: add only DC powered USB hub and connect the printer to one of the ports of the hub-s. Let Windows install the drivers for the USB cable and printer and printing is perfect!

    It is that the laptop USB ports do not have enough current or voltage, especially if some other USB devices are connected to the laptop...

  • No sound from Internet Explorer / Sound of ok media with USB speakers player and without.

    Please can someone help... I am running Vista Home premium on a Toshiba Satellite Pro A200 series. I ran diagnostics and any other thing, I see... I can get good sound play anything through Media Player... But no Internet Explorer sounds... makes no difference with or without USB speakers. Have upgraded to IE 8 to IE 7 - not make a difference.

    I just encountered this problem but luckily managed to solve it easily. I got guitar pro running playing sound normally and IE wasn't when you run simultaneously. I closed gp and IE worked as usual. I didn't know this before with these two programs, but I would say that if you have this problem try closing unnecessary programs and restart ie.

  • Sensor with Signal conditioner for the acquisition of data NI 6009 force

    Hello

    I currently lead a unique test by using a pendulum. Currently, there is a rotary potentiometer measures the rotation of the shaft and a force sensor to measure the impact. The Rotary potentiometer and data acquisition work like a charm in SignalExpress but I currently have problems with the force sensor.

    The installation program:

    Sensor Signal conditioner box-->--> DAQ (analog input 1 & corresponding to the ground) by force.

    In Signal Express, when I "Add Step" process - should I choose "Acquire signals--> DAQmx Acquire--> analog input--> [voltage? The force? Custom?]

    Thank you 1 million,

    AW (big noob)

    Hi a_wishart,

    I don't think that the evaluation of Signal Express version is the reason for which you get this error, see the related document, there are several possible causes of this error.

  • Difference between DAQ and DAQmx for acquisition of data PCI 6534

    Hello

    I use the PCI DAQ 6534 card for my digital I/o transfer. I am beginner in the labview.

    I want to store the data coming in memory and the reading of the data at the level of the trigger.

    I have seen the examples in the labview. Some have used DAQmx and DAQmx read write that screws and some have used the confg DIO port and all...

    So I want to know the difference between these two. For my application that I use?

    Hey Bo,

    First of all, I would recommend that you discover the NI 6533/6534 for NOR-DAQmx help. You may be able to find some of your answers in this help document. Now for what you try to do in your application, it looks like you are only buying data. If this is the case, with the 6534, the device acquires data in memory shipped as soon as the DAQmx series start task VI, as long as you don't start hardware triggers have in place. If you have a trigger of starting material, then will make the purchase of the aircraft after the DAQmx start task VI and only after you receive this material trigger. If you call not the DAQmx Read VI, then the data will be stored in the memory board for you, as the driver manages this data in the on-board memory storage, until reading DAQmx VI is called, which at that time, data is transferred to the Board of Directors in the memory of the computer. Once you get it in the computer's memory, you can do whatever you want with these data, as this graph or treat. If you look at the sample programs (which have been mentioned on how to find those in a previous post), you can find an example that little shows you how it works. One of the examples that you can check is called reading Dig Port-Ext Clk.VI. In this example, it sets up to read a finite number of samples and then starts the task. If you set a breakpoint on the line of the error after the VI begin, the data will be acquired in the amount of on-board memory. Then when you cancel the break of the VI, data will be extracted from the amount memory embedded in the memory system with the reading VI DAQmx. Again, the pilot takes care to put the data in the memory board for you once you start the task.

    I hope this helps. Please let us know if you have any questions or concerns about this issue. Also, certainly, discover and try to run all the programs related to the 6534 examples so that you can learn how the equipment works and how to use features to do what you want your program to do. Also, be sure to read through the help on the 6534, as well as the help of VI documentation to learn what makes each function. Thank you and have a nice day.

    Kind regards
