Tek TDS3052 driver vi runs into timeout

Hello,
it's me again with a problem concerning the Tek TDS3052 scope.
I tried to read a measurement from it using the "tkds30xx read measurement.vi" (to be more exact, I wanted to read a voltage average value from Channel 1).
Most of the aquisition parameters were set by hand an the oscilloscope. By software, cursor gating was turned on using the "tkds30xx configure measurement.vi", and the scope was set to "continuous aquisition" using "tkds30xx configure initiate continuous.vi". (I intend to collect this average value for each trigger event received by the oscilloscope).
If I call the "tkds30xx read waveform measurement.vi", the function waits until its predefined timeout (5000 ms) and then returns a timeout error,
although the scope display shows it's being triggered and acquires data (at a rate of 20 Hz). Running the corresponding "tkds30xx fetch waveform measurement" returns the value I want from the last aquisition, but, of course, doesn't wait for a trigger event.
Does someone of you know how to employ the readout function correctly to aquire a value?
Thanks in advance for your help.
Best regards
Kristian Laß

Hello,
unfortunately the same problem occurs if I try to employ the example application that came with the driver VIs - this produces a timeout as well.
Nevertheless, I tried to employ the trigger configuration VIs in my application - without success. (I didn't consider it necessary at first because I set most of the settings on the oscilloscope's front panel)
I'll post an example of what I worked out for myself along with this posting.
Thanks for your help!
Best regards
Kristian Laß

  • What if computer run into "Bootmgr is missing" or "Hard Drive Failure"

    Most of us have the experience of computer run into error,such as bootmgr is missing. The most common reasons for BOOTMGR errors include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose hard drive interface cables. Hard drive failure is another frequent error,it is arouse by physical damage or logical error. Once this problem occurs to you, any data stores in it would be in danger.  If you want to Fix Bootmgr Error by yourself. These following steps may be available for you to deal with the problem. Step one. Burn a rescue boot disc or USB drive. You need to download Fix Genius and install it  into a computer ,then insert the CD/USB and run the program to burn it . Step two. boot your computer from CD/USB Enter into the BIOS and change the Boot Device Priority ,then save the changes and exit. Step three.Fix "Bootmgr is missing" or "Hard Drive Failure" Insert the CD/USB then you will enter into the WinPE system, and click the Fix Genius icon there on the desktop. After run up the program, config the parameter according to your problem. This rescuing process would last within minutes. It is the best one I can find among the solutions. As the time past, it is a time information refresh very quickly, Maybe there is a better one for you to fix bootmgr is corrupted and Hard drive failure if you have time to search online. please let me know if you find it, I will be glad with you.

    There are some caveats to be aware of when replacing the hard drive! While in theory any SATA drive is compatible, I have experienced problems with a Seagate Momentus 5400.6 500GB and a Western Digital Scorpio Blue 640GB recently.
    With my WD drive I have had to adjust the power management settings (using a command line tool called "hdapm") to prevent it from spinning up and down every 20 to 30 seconds, and which was also leading to momentary freeze ups. While this may kill my battery a bit quicker, I'm hoping the drive will at least live an average lifetime. (Batteries may be more expensive, but they're a lot quicker to replace than a hard drive).
    My Seagate drive has exhibited far less frequent problems but the occasional noises it made have never sounded healthy and after 6 months is now being replaced under warranty. There were also a number of days where I would get excessive beachballing for no reason I could identify, and that I concluded must be hard disk related. I couldn't find anything here or elsewhere on the internet to indicate what the cause of that might be.
    So my limited experience of hard disk replacement hasn't been a great success and I'm beginning to wonder if getting an official replacement from Apple might be a safer option in the long run, despite it being more expensive. I read somewhere that the hard disks supplied by Apple have custom firmware that works better with Apple's own power management strategies.

  • How do I control the TEK TDS3052 by LABVIEW installed in a PC?

    I used the "crossover" cable directly connect the PC and the TEK TDS3052(with a ethernet port).What I have done is that I configured the ethernet parameters( the IP adress, the net mask etc.). And when I apply the "Ping" command in the "run" window of the windows 98, there is a correct return.So the ethernet network is well done.Now I want to use the LABVIEW to control the oscilloscope. But I don't know then.Who can tell me the detail steps which I can take next, thanks a lot.

    Kevin,
    Which version of LabVIEW do you have?
    There are two ways of controlling your oscilloscope from LabVIEW, one is using the VISA functions (instrument i/o palette in LabVIEW)and another one is using an already built instrument driver, which you can download by going to zone.ni.com, and then click on "resource library" at your left... then click in "instrument drivers", and then in "downloads" and then type in the "additional keywords" box type "tds 3052" and click SEEK... you will find a link for your instrument there... you can download that instrument driver and it fully functional with LabVIEW, now... the truth is that I have always used this drivers with a GPIB interface in the computer, in this case is only going to be by TCP/IP... so you can try to adapt the addresses instead of using an instrument type address, use the TCP/IP instrument type address and give it a try to see if it works. The address type for TCP/IP is stated below.
    First you need to have the latest version of NI-VISA installed, 2.5.2, which is shipped with LabVIEW 6i (version 2.5.0 and then download a patch for 2.5.2).
    Our solution for controlling instruments with Ethernet ports is NI-VISA.There are two possible situations:
    1) Instrument supports the VXI-11 protocol.
    The VXI-11 protocol was created to control instruments over Ethernet using the GPIB style. It has nothing to do with VXI, but it was there were it got approved.
    NI-VISA supports VXI-11 instruments, to the point that the only change in the instrument driver written with VISA is the identification string. Instead of using GPIB::1::INSTR, you can use TCPIP::ip address::instrument name::INSTR. (For example, with the Tek TDS 3054, the string would be: TCPIP::130.130.130.1::gpib0,1::INSTR). (Note that 'gpib0,1' has nothing to do GPIB..its just a name given to the instrument..it could have been just 'tds3054' also if the instrument vendor chose to do so).
    2) Instrument DOES NOT support the VXI-11 protocol.
    In this case, you can still use NI-VISA to talk to the instrument using the NI-VISA Ethernet Sockets functions. However, you would have to take care of the specifics of the protocol used for the instrument. The instrument manufacturer should provide you with the details on how to control the instrument (commands, parsing, etc.).
    *** Tek's Scopes ***
    Tek introduced an ethernet interface for some of their scopes. We have a TDS3054 scope from Tek that is VXI-11 compliant. Since the TDS3054 is VXI-11 compliant, we used it at NIWeek to show how you could control it using the same code written for the instrument with the GPIB interface, by just changing the identification string.
    NI-VISA 2.5.2
    NI-VISA 2.5.0 introduced the support for instruments with Ethernet ports. Notice that LabVIEW 6i ships with the older 2.5.0 version. The patch to upgrade it to 2.5.2 is called NiViEnet.dll and is located in the ftp site at:
    ftp://ftp.natinst.com/support/visa/drivers/win32/2.5/patch/
    So you can try this Kevin and see if it works for you, contact us back (www.ni.com/ask) if you need further assistance.
    Good luck!...

  • Admin server running into issues in SOA.

    Hi All,
    Can anyone help me.
    I have recently  installed Oracle SOA suite on Linux box. While I was running the Admin Server I am running into Some issues. Though Admin Server is running fine but all that I am running out of memory because of the Logs. Can anyone help me find the issue and solve. I can do some other arrangements to save memory. IF you could help me for any issue I would be so happy. One more thing SOA suite installed on Admin server instead soa_server1 or soa_server2. I still need to SOA-infra setup onto soa_server1 or soa_server2(on different remote machines) [if this info could help also.]

    Thank you all.

    Hi Ravi,
    You are much appreciated for your valuable time and knowledge..
    Then delete old domain. Its corrupted. You can clean it by manually updating jdbc datasource files under config/jdbc folder. But I will NOT recommend this. Just delete this domain folder and from user_projects/appliations also delete the folder with same domain name.
    Create a brand new domain using config wizard. Select SOA or BPM whichever you want, and also Enterprise Manager. Then at database, carefully select 11.7 Schemas that you created earlier.
    Though I have not created a new domain. (still Ravi is correct)
    Issues were resolved by updating the new RCU schema with latest version of RCU 11.1.1.7.
    Here What I did is ran the rcu.bat on my local and connected to remote DB.created new schema for each components namely soa-infra,orabam,owsm,MDS. with a new prefix.
    I did not drop the previous schema for SOA.
    went to  *Domain-home*/config/jdbc/
    took the back up for all the *.xml files excluding read.xml(anyway its just an info file).
    Now edited the schema component. Someone might change their schema component password. but my suggestion is not to give any new passwords to the schema components while creating new RCU schema for SOA.
    What I did is changed the component passwords (I know how to mess up and also know how to fix if it's messed up) and ended up with errors.
    So I have now started the server with the command
    ./startWebLogic.sh -Dweblogic.configuration.schemaValidationEnabled=false
    Still I had errors coming up. But I least bothered about the errors because these errors can be solved once get to know what you are doing.
    My server started. Happy then
    Went to admin-url:port/console
    then  Home>Summary of JDBC Data Sources
    next lock & edit
    select each jdbc component and changed the password and confirm password for each
    then save each time for each  next  activate the changes.
    (as I changed all components passwords like <password-encrypted>asdl;lasdfadf=<password-encrypted/>   to <password>welcome1=<password/> in each *.xml file at *domain-home/config/jdbc*)
    I have restarted the Admin server from Command prompt. Expecting that I was doing correct.
    Succeeded. I did not believe that I have seen not even a single error.
    My sincere request that don't mess up with any *.xml file if you are not sure and make sure to take a back up
    Thank you.
    Thanks a lot.

  • Can I create MacOS on flash drive to run broken Imac?

    So I've got an Imac that's all brokedy. Won't start up. I tried reinstalling Snow Leopard 10.6.7 on it from a boot disk, but got referred to Disk Utility. Disk Utility told me that the GB 500 drive was so fricked up that Disk Utility can't do a thing with it, I have to take it to a repair shop. But the Apple MacIntosh HD that's INSIDE the GB500 drive checks out OK according to Disk Utility.
    It occurred to me that I could maybe install the Snow Leopard software into a flash drive and run the computer off of it, accessing the data and software on the MacIntosh HD via the flash drive, and at least being able to salvage important files that way. I'll need at least a 16 Gig flahs drive for that, no biggie, but my question is: is this feasible or some mad fantasy I've created out of an absurd desire not to get my wallet hijacked by Apple?

    I think you'll find that your Hard Drive is failing, I hope you have some form of backup.
    Your idea of creating a bootable flash drive could work but it will be useless if your HDD fails which according to your SMART status could happen soon.
    I would make a full backup of your hard drive onto an external hard drive using Time Machine or another preferred backup method.
    Then I would look into replacing the drive by myself or taking it to an Apple Store.
    Good Luck!

  • I currently have a MAC Mini, which has 1 Firewire 800 port.  I have a 1TB external hard disk that runs at Firewire 400.  Can I insert another external hard drive that runs at Firewire 800?

    Here's the deal.  Currently running SL 10.6.8 on a MAC Mini.  Planning for eventual upgrade to ML.  Have a 1TB external hard drive partitioned into two volumes, one volume for Time Machine and one volume for SL which I periodically update using Superduper.  Thus I always have a point-in-time bootable backup on the external hard drive.
    The MAC Mini supports Firewire 800.  However, booting from my current external hard disk is pretty slow, since it only supports Firewire 400.  I am considering buying an Iomega MiniMax which supports Firewire 800.  Then, I would use the MiniMax as my bootable backup volume, and relegate the older hard drive to Time Machine. 
    So, question #1 is, can I daisychain the new MiniMax between the MAC Mini and my existing external hard drive?  My expectation is that the new Mini Max would run using Firewire 800 and that the existing hard drive would run at Firewire 400 speed as it does today.  If it doesn't (e.g., daisychaining in the Firewire 400 external disk with the MiniMax Firewire 800 external disk ends up running the whole leg at 400), my resolution will be to run the existing hard disk off an available USB port and have just the MiniMax running at Firewire 800.
    Why am I going to all this trouble?  That's question #2.  I don't trust upgrades; they always break something.  When I upgraded from 10.5.x to 10.6.x, the web directories got renamed, and all of my web apps 403'd until I figured out what happened.  Plus, I have accounts for other family members, and in order to ensure their ability to use the computer during my upgrade process, I need to have the ability to fall-back quickly to a known-stable version of OSX.  So what I'm trying to do is insulate myself from problems by partitioning the MiniMax into two volumes, taking a Superduper image of my current installation on the Mac Mini to MiniMax external drive volume 1, then upgrading to ML on the MAC Mini, and take a SuperDuper image of that to MiniMax external drive volume 2.  Then, if the upgrade results in problems I can't resolve immediately, I can simply reimage the MAC Mini from MiniMax volume 1.  BUT ...
    ... I've read that the ML installation creates a "service and support" partition that is different than the startup disk.  I'm concerned that I won't be able to reimage the hard disk in the MAC Mini once I upgrade it to ML because of the partitioning changes it introduces on the startup disk.  Theoretically, I +should+ be able to use the disk utility on my SL system to repartition the disk in the MAC Mini prior to reimaging it from my backup, but I'm considering the possibility that the new partition may be of a type that the SL disk utility cannot identify, and might therefore be unable to delete or even detect.  So I'm hoping someone else has been down this road and can advise me.  Even at Firewire 800 speeds, booting from an external disk is still going to be slow, so I want to be able to restore my SL image to the MAC Mini hard disk.
    A little background on me.  I work for a major disaster recovery provider.  I used to have a Mac PRO G5, which I got used, and the first thing I did with it was install a second hard disk, SuperDupe an image from the first disk to the second, and made sure I could boot from the second.  THEN I started using and customizing the MAC.  I really feel vulnerable with the MAC Mini, since it only has the single internal hard drive - sort of like going out in public dressed only in a long T-shirt.  So my whole thing is, I ABSOLUTELY MUST BE ABLE TO PUT THINGS BACK THE WAY THEY WERE before I do the migration to ML.
    Obsessive-cumpulsive?  Yep.  Anal?  You got it.  That's why I'm in the DR business.

    What kind of trouble I may run into?
    Where are the hidden catches?
    What can go wrong, and how can i undo any mistake?
    I also have an iTunes Match acccount.

    HI
    Read this user tip Make and keep a backup of your iTunes library, and only stream from the cloud.
    Problems? No hidden catches. Whilst streaming using match, you will need a wifi connection. You main worry is that if your NAS drives fails, you need to redownload your music from match but this could take time depending on how large your collection is. Personally I keep an additional backup of all my music as a matter of course.

  • When I am re-installing the Mac OSX snow leopard onto an older Mac I run into the window that says select the disk where you want to install Mac OSX but nothing is there to select

    I am trying to re-install the Mac OSX snow leopard onto an older I mac with a new hard drive.  I run into the "select the disk "where you want to install Mac OSX but there is nothing in the window to select. Any advice?

    After you install a new hard drive, you need to boot to another drive to initialize it to MAC OS Extended (journaled) format and create the partition(s) on the drive. You do this using Disk Utility. Otherwise, the mac operating install process doesn't see a formatted disk to install to.

  • How can I boot my (OS Lion) Macbook (using external drive) to run Leopard

       I have recently installed Lion on my macbook. Previously, I had Snow Leopard.  During that time, I used an external hard drive to boot into Leopard to run some programs that didn't run on SL (Spring Cleaning, for example).
       Today is the first time I tried to boot from the hard drive with Leopard on it since upgrading to Lion. Hitting Option during startup doesn't even show the external drive, and using the System Preferences/ Startup Disk method is equally useless.
       I like Lion and don't feel like doing a total re-install just to have occasional access to an older OS, but I'd sure like to have it all!
      Any ideas for a workaround?

    Verify that your external drive was formatted as GUID, it won't be bootable otherwise.

  • Suddenly, I can't boot from my alternate drive (which runs 10.4.11)

    I run OS 10.6.8 on a Mac Pro 2.66 Ghz Dual Core. On a separate drive, I run OS 10.4.11 (for some older software).
    That setup has worked for years. But today, I can't start up from the 10.4 drive. When I go into System Preferences: Startup Disk, the 10.4 drive shows as an option. So I select it, and click Restart. The Mac then takes a long time, as though it can't find the 10.4 drive, and finally restarts from the 10.6 drive.
    The only clue I can think of is that I used Disk Utility yesterday to repair permissions on the 10.6 drive. I MAY have used Disk Utility also on the 10.4 drive, though the only options are verify disk and repair disk--and I don't think I did any repair.
    Disk Utility says the 10.4 volume appears to be OK.
    Can anybody help me? Thanks in advance!

    I'm not entirely certain of this, but I don't think you need the BR2032. The CR2032 is what OWC sells for Mac Pros. They're very cheap there, but you'd have to pay for shipping and then wait. You can easily find a CR2032 for around $5 or less at a Radio Shack or even a CVS or any chain like that.
    So what's the difference between a CR2032 and a BR2032?
    Most lithium cells have a nominal terminal potential of 3 volts. Like other types of primary (i.e., non-rechargeable) cells, however, their voltage isn't perfectly uniform over time and use. Because of somewhat different composition, the BR-type cells yield more uniform voltage over most of their useful life, but near end of life, their terminal voltage falls fairly rapidly. Because of that, they are often called constant-voltage lithium cells. CR-type cells, on the other hand, exhibit a more gradual decline in voltage over most of the discharge period, and thus they may give somewhat longer service in circuits designed to tolerate a wider range of terminal voltage, and they tolerate higher continuous load currents. In addition to typically having somewhat higher rated capacities, they also tend to cost less than their BR-type counterparts, which largely accounts for their greater popularity.

    I wouldn't use a tweezers. Could cause a short in the PRAM circuit and really ruin your day. Maybe a strip of non-skid rubber to grip it and slide it out carefully with your fingers. But do be certain to ground yourself before doing this, in case of any static electricity buildup. Might even get a wrist strap (I got one from RS, but that was years ago. Don't know if they still sell them). Then again, if you're in the US, it's probably humid enough right now where you are not to have to worry about static electricity buildup and discharge wrecking a tender chip. Something more to be concerned about during dry winter days. Just ground yourself first on a radiator pipe and then momentarily grip the Mac Pro chassis while you are engaging any of the components.
    I would definitely change the battery. 7 years is about the limit for one of those lithium coin cell batteries.

    No obstacles.  After he rips the CDs into audio files, copy the audio files from his PC to a flash drive or an external hard drive.  From there, add them to your iTunes library on your Mac.
    As long as he uses one of the "taggable" audio formats -- MP3, AAC, AIFF, or Apple Lossless -- they will come up correctly on your Mac.  Just make sure he avoids WAV format.

  • HD failed on iMac 7.1. How do I use external drive to run computer?

    I have an iMac made in mid 2007. It is an Intel Duo Core processor. The hard drive has failed. Apple says I can use an external drive to run it. I have a installation disk for Snow Leopard. How can I install Snow Leopard onto the external disk given that the computer is unusable?

    If no way to have an internal hard drive installed into your iMac, then you will need to purchase two good quality, large capacity FireWire 800 (fast data transfer connection) external hard drives.
    FIreWire 800 drives will give you an operational speed close to the same speed as your iMac's internal hard drive.
    One external hard drive will be used as your iMac's main working drive. The other drive is to be used to create either cloned, bootable backup drive or to be used with OS X Time Machine backup app.
    To install OS X Snow Leopard onto an external hard drive, if your iMac's optical drive is still working, power up your iMac holding down the C key on the keyboard and immediately insert the install disc into the optical drive slot on the side of your iMac.
    Your iMac should boot up to the system that is on the install disc.
    Once you are in the Installer app, go up to the main menu bar and quit the installer.
    Then on the main menu bar launch the Disk Utility app and format the external drive for Mac OS X Extended ( journaled ) format with a GUID partition scheme.
    You can decide if you want one larger partition on break the drive down into more than one partition for data storage purposes or not.
    Once the drive is formatted, quit Disk Utility, relaunch the OS X installer app and proceed, following the instructions to install OS X Snow Leopard onto your external drive.
    Once installed, you'll be prompted to restart your iMac and it should automatically find where OS X is installed and boot up your Mac to OS X.
    From there, you can go into OS X Preferences Panel and select the software update feature of OS X to update your OS X version to OS X 10.6.8 and all of your Apple installed apps.
    In OS X System Prefrences panel under Startup disc icon, click the icon and set the startup disc for the external hard drive that shows your currently installed OS X system.
    This OS X will know where OS X is always launched from and won't have to hunt for it when you always startup your Mac.
    You will have to reinstall all your third party applications, too.
    Good Luck!

  • Does anyone else run into Robohelp 11 hanging on startup?

    I've tried three installations.  I'm running RH 11 as Administrator, on Windows 7.  It hangs on the splash graphic, during "initializing user data".  It eventually does arrive at the workspace, it just takes quite a long time.  Maybe that's normal, I don't know Anyone else run into this?

    I would try uninstalling using Revo Uninstaller Free Version if this is a 32 bit version. I don't think there is a free edition of the 64 bit version. Then reinstall.
    Was Rh was installed to C drive program files in the normal way?
