Generate a '2 output instrument​' directive to IVI driver

Hi,
 I have a Tektronix AWG420 which I didn't find drivers for anywhere; however I did find an IVI driver for the AWG5x0 family in the NI drivers' zone.
As the command set for these instruments is almost identical I tried using it, and it works great with my applications for Channel1 if I turn of the 'ID query' at initialization.
However, as the driver doesn't recognize that I have a 2-output instrument I can't communicate with Channel2.
Does anyone know how can I give directives to the driver that this is a 2-output instrument?
Thank a lot,
   malosh

Unless you want to buy LabWindows/CVI and modify the driver (orf ind someone to do it for you), I think your only option is to use tkawg5x0 Write Instrument Data to send the unsupported commands. This (and a read function) are on the Utility Functions>Instrument I/O palette.
Since doing this makes your program instrument specific and you lose most of the reasons for using IVI, you could always write a native LabVIEW driver or use the Instrument I/O Assistant instead of the IVI driver.

  • XML Publisher Report not generating the PDF output.

    Hi,
    I am trying to develop a XML Publisher Report in R12 Vision Instance.
    I have developed the rdf report and concurrent program with XML as output format. Ran the concurrent program and I got the XML output. Based on XML output I have created the rtf template. Using both the template and xml output I have created in Data Definition and Template in XML Publisher Administrator Responsibility. Now I am comming to the concurrent program and running the program, here instead of generating the PDF output it is generating again the XML output and concurrent program completing with warning status.
    When I am trying to do the same in 11i Vision Instance, Concurrent Program completing with normal status and when trying to view the output it is saying "Unable to Publish output for the Processed Request".
    Kindly please help me out in this issue.
    Thanks,
    Manasa.

    Hi Mahesh,
    Here the concurrent programs are not erroring out. It is completing with Warning status and when we click on View Output the output is coming in XML format instead of PDF, this is in R12 Vision Instance.
    In 11i Vision Instance, concurrent program is completing with Normal Status but when we click on View Output it is saying "Unable to Publish output for specified request".

  • Using mathscript to generate multiple digital outputs for switch control

    Hello 
    I am new to this NI LV and a have kind of a basic question. I would like to use Mathscript to generate an array of bolean numbers which will be used to control the Digital I/O lines. I am using NI 6251 USB device and the Mathscript code runs well. But I have a problem using this array to control the Digital output. So I created a simple test programme where I set the DAQ assitant to generate 4 digital outputs(P0.0 ~ P0.3) and it gives error that  ".. number of channels in the data does not match the number of channels in the task..." (see attachment) . How can I solve this problem thank you.

  • How to generate multiple digital outputs (square waves delayed) at 50 kHz?

    I would like to generate 3 digital outputs like the picture attached at 50 kHz. Using the "digital pattern generator (marching values).vi", I can generate 3 digital square wave but without the delay time. How can I do that?
    I'm using the card PCI 6034E.
    Thank you

    Hi,
    the digital pattern generator (marching values) only shifts the binary value of the first signal and sample to the next signal/sample.
    Have you tried generating your waveforms via build waveform and use t0 terminal to change the lead delay?
    In general, this DAQmx example could be helpful which you can modify to your needs.

  • Using iDrum as a multi-output instrument

    Hi all-
    Maybe someone else uses iDrum as a drum sequencer/scratch drum instrument like me.
    I can't seem to instantiate iDrum as a multi output instrument...only stereo.
    I know how to do this well in PT, but it has eluded me so far in L8.
    I am:
    Creating a new instrument track, selectin the i/o as iDrum and there is no multi output option as there is in ultrabeat.
    It is probably something simple...usually is
    any help appreciated greatly!!

    AFAIK, there is no multi-output support for iDrum with Logic 8, although you could select a multi-channel option in LP7.
    What you can do is bounce pattern/song to separate .aiff files from the iDrum menu and reimport them on to audio tracks.

  • Error when generating waveform analog output on NI 6704 card

    Hi, I am trying to understand why NI 6704 card appears to be incompatible with what I'm trying to do. 
    I want to use a waveform to generate an analog output voltage on a NI 6704. 
    I have a vi in the style of the waveform buffer generator in this example:
    http://zone.ni.com/devzone/cda/epd/p/id/4837
    which creates the waveform. In my main routine I attempt to create and write a DAQmx ao task using the waveform information, but get this error: 
    Possible reason(s):
    Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
    Property: SampTimingType
    Requested Value: Sample Clock
    You Can Select: On Demand
    Task Name: _unnamedTask<7D>
    According to documentation the 6704 has no onboard memory... but it's not clear to me how the DAQmx functions are actually sending the data to the card, i.e. if they are attempting to read and store the waveform buffer on to the card, it the lack of memory on the card could be my problem. Is is correct that that is part of my problem? Or since the error has to do with the sample timing clock, is my problem that the 6704  uses software timing? 
    I've run my program successfully on an NI 6225 card... are there any work arounds for generating such an output on a 6704? 
    Thanks in advance!

    The error has everything to do with software timing. Your device does not have a hardware clock so you get an error when you try to configure it. To output a waveform, you have to do out one point at a time. You can only do this at a low frequency and it will have considerable jitter.

  • Generating 508 compliant output for access via SharePoint

    In order to make our WebHelp application accessible via a Sharepoint folder, our team lead was able to move all output files (from the ISSL/WebHelp folder) to a single folder then move the files from the resource, whdata, whgdata and whxdata folders to the same [new] location so that all files associated with the RoboHelp WebHelp project are in the same area.  Next, he edited the whproj.xml file and changed the datapath from "whxdata" to " " (null). This works fine for primary layout output that isn't 508 compliant, so I duplicated the same steps after generating 508 compliant output to see if I'd get the same results.  After moving all files to a single folder and uploading to a test server (not Sharepoint), the table of contents page [frame] "can't be found".  I know that the toc tag in the whtoc.xml file has a root attribute that points to "whtdata0.xml".  This file is in the same folder as everything else.  So why does it not show the TOC?
    Thanks,
    Developer2000

    Perhaps the best way to answer this is to ask what your response would be if your support people came along to you saying a customer didn't like the structure of the folders in your application so they had rearranged them and now it would no longer work, what should they do?
    Perhaps best not to post the reply here.
    The folders and files that RoboHelp generates have many inter-dependencies and it could be some are in files you cannot edit. Who knows? It is not something Adobe would document and I have not seen anyone post anything that would help you.

  • Third party muti-output instrument

    Hi,
    I am attempting to make use of the multi output facilty in NI's Battery 3 in the same manner you would with Ultrabeat when you selct it as a Multi-Output Instrument. Battery has the same facilty but I cannot seem to figure out how to utilize it in Logic!
    Thank you, thank you.

    NI and Logic now seem to work a little different than in 7 ( or maybe its NI in version 3) at any rate before you were able to just select multi instrument and add channels as you went. Very elegant. Now you have to select from a predefined list of mono/stereo configurations. To do so now, choose a configuration of mono and stereo channels. Now add aux channels from the mixer (option/create new auxiliary channel strips) now just select the appropriate battery channel for the input.
    hope this helps

  • LabVIEW 2-output instrument into Multisim

    Hi, buddys!
    I'm trying to bring two waveforms into Multisim by means of project provided by Patrick Noonan here:
    http://forums.ni.com/t5/Circuit-Design-Suite-Multisim/Create-a-LabVIEW-Based-Virtual-Instrument-for-...
    I added in Patrick's Simple Output Instrument.vit another waveform and connected it to one more terminal added. The project builds and the new instrument adds to Multisim just fine.
    The thing is that only one waveform is "working" while the other one (another output) is always zero in multisim. Though both are non-zero in correspondance with front panel.
    How to make one more waveform "work"?
