It would have helped if you would have stated that this was for a Tektronix 7000 series scope.
I see two possible issues here:
1) The scope never sees the trigger and therefore never sees a waveform to capture
2) The scope is setup to continuously capture waveforms. Since the scope isn't stopping, it won't report being complete.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Timeout error in Wait for Operation Complete VI for TEKDPO4054 scope driver

Hi,
I keep getting a timeout error (-1073807339) when I run the "wait for operation complete" sub-VI that comes with the tektronix DPO4000 series oscilloscope driver. I'm using a DPO4054 scope. The error out source is the VISA Read STB command, but I can't figure out what's wrong. Has anyone else encountered this error? Please help!
Thanks for your time!
I've attached the sub-VI where I'm having this problem.

MS2026 -anvna Wait for Acquisition Complete -ERROR

Hi Everyone,
I wrote a labview program (LV 7.1) with instrument MS2026A VNA (Anritsu) and it was working fine.
However the original equipmet stopped working last week and we have received a loaner (until our is fixed), same model, but does not work with my labview program. I even try running this equipment with the sample program provided by NI: "anvna Acquire Trace Example" and it gives me an error -please refer to attached pictures.
The error is in the "anvna Wait for Acquisition Complete.vi." I think it has to do with timeout (256). I have added delays all over but nothing helps. I used to have this same problem on the first instrument but it disappear "mysteriously."
Could somebody point me to way to fix this issue? Thanks very much,
Frank

Hi Fvalenzu,
I have a few questions about your application.
Is the replacement instrument the same revision of the instrument you sent to get repaired?
Is the device at the same address?
Are you able to successfully communicate with the instrument in max using GPIB commands?
You might want to verify the program is calling the instrument by the correct alias or address and you are calling the device correctly. Also, I would check and see if there is a newer version of the IVI driver for your instrument. IVI drivers can be found at the link below.

Pourquoi une erreur s'affiche t-elle toujours dans le VI "wait for operation complete" ?

Bonjour,
J'ai un programme avec lequel je relève la courbe présente sur deux oscilloscopes et qui permet de surveiller l'état du trigger de ces appareils et d'enregistrer des fichiers de mesure. Cependant en utilisant le vi "Read multiple waveforms" il y a une erreur qui apparait dans le VI "wait for operation complete" et je n'arrive pas à trouver la cause de cette erreur ! Pouvez-vous m'apporter votre aide sur ce point ?

Bonjour ttom972,
Je ne trouve pas de driver s'intitulant Tektronix 7000 series sur notre site. Avez vous un lien ?
Les drivers d'instruments disponible sur notre site ne sont pas développés ni supportés par NI. Je peux essayer de regarder d'ou provient l'erreur, mais le mieux serait de recoder en utilisant des fonctions bas niveau VISA.

Wait for move complete not waiting for timeout

Hi,
I am running a small rotary stage with a 7358 motion controller. Occasionally when I command a new position, the "wait for move complete" seems to get triggered almost immediately even though the move is not complete. Since I have put in a "halt" downstream of this to cover the case where the move times out, the move stops immediately. The problems seems interrmittent but I haven't discovered a pattern yet except that is happens for more often when making a reverse move, i.e. I go to 1000 counts as a forward move and then back to 800 as a reverse.
Has anyone seen something similar?
Thanks,
Dave

oops syntax error! I put waitComplete, but it's supposed to be moveComplete as the last argument for flex_wait_for_move_complete. Just want to let you guys know that. Thanks!

Waiting for Task Completion from multiple users

iam using Weblogic8.1 Integration BPM to design a worklist application. I need
to create a number of Tasks(number know only at runtime), assign to users and
wait for the completion of each of these task. I've tried using the Task Control
factory to accomplish this. But iam not able to hold the process instance execution
till each of these task is completed. The control gets released from the TaskControlFactory_onTaskCompleted
as soon as one of the above created task is completed.
Pls. let me know if there is a way to achieve this.
Regards
Raja V.

Try to put the onTaskCompleted Control Receive in a loop which counts how
many of these
callbacks have already arrived, and the loop exit condition would be that
the count is equal
to the number of the created tasks.

Iphone 4S stuck during restore, waiting for iPhone message error 9

yesterday morning when I woke up to check my Emails on my iphone 4S, my phone was complete dead. I thought battery died so plugged into charger. but even after couple of hours it didnt turned up. So I started force starting by pressing power button several times but nothing happened.
Then I pressed both home and power button for several minutes, nothing.....
Finally I connected my iphone to itunes thru my Mac air and to my surprise it said my phone is in recovery mode and needs to be restored. I pressed ok, it extracted software and then said waiting for iphone. and I was happy to see apple logo on my phone with a progress bar. I waited for almost 12 hrs but nothing moved in the progress bar. seems like it frozen. I tried disconnecting and reconnecting to itunes but everytime same error. whenever i plugeed out my phone from itunes, it errored out no. 9.
Also it is not showing any s/n for my iphone in itunes. I am very confused and frustated, read many forums and also updated my itunes, updated my software and turned on the firewall too. NOTHING HELPED.
Does anyone have any solutions to share?
Thanks

"Insufficient access privileges for operation" Export Error

I have been working on a very important project in iMovie 09 and I went to go export it into quicktime format, and I get an error that says "The movie could not be exported because an error occurred. (Insufficient access privileges for operation )"
I have the video files on an external drive, and I know based on the error message that it has something to do with the privileges of the video files. I just don't know how to fix it. Hopefully you can help!
Thanks

This may not be your problem, but you may want to check. By default, permissions are ignored on external volumes. Select the external volume with your video files on it and go to File --> Get Info. At the bottom of that window, make sure that "Ignore ownership on this volume" is checked. If it is not, check it. (You may have to click the "lock" and supply your administrator password first.)
If it is checked, then the conflict is with some other file(s), in which case, someone else will have to help you with that.

Why Waiting for App Store to download Mac OS X Server Add On. stopping Lion download?

I just purchased Mac os x lion and this message is popping up : Waiting for App Store to download Mac OS X Server Add On.
Help! How do i get it to install?

Ran into this myself on a new MacMini Server. I renamed the ServerVersion.plist file in /System/Library/CoreServices/. That allowed the install to start. Unfortunately it seems the installer is setup to install that at the same time. I renamed the file back before the restart and it complained on restart that the server install wasn't found.
So I thought I would try downloading it on another computer with Lion. That didn't work either. As soon as it finished download it installed and deleted the installer.
What a pain.
If you can start from scratch, you should be able to rename the file, do the Lion install then after the Lion install rename it back. Then do the server install. I'm not sure what that will do to existing server configs though. There must be some reason Apple set up the Lion installer this way.
Oh, now I can't reboot into my existing OS. It keeps rebooting into the installer. Tried the option key and both options are named something like base os. Neither boots my existing Snow Leopard. Gonna have to get an external DVD drive and install from scratch I think. Luckily this is a new server not in production, so not a big deal. I hope people with production machines read the boards and tread carefully.

Flex wait for move complete

Hi,
I am currently programming a 7344 motion control board in Visual C++.
Right now I am using the function flex_wait_for_move_complete function but it causes an exception error when passing the pointer, moveComplete, into the function ( it is the last argument).
According to the prototype, u16* waitComplete is a returned pointer the function returns. 1 if move is complete, 0 if move is not. Maybe I am referencing it and using it the wrong way.
In my function
void moveSingleAxis(..)
u16* moveComplete = (u16*)1;
//some code
status = flex_wait_for_move_complete(boardid, NIMC_AXIS1, NIMC_AXIS_CTRL, 10000, 20, waitComplete);
//status is used for error checking, but irrelevant to my problem
If I make the pointer to 0 or NULL, flex will error and say pass in null pointer . If I make the pointer to any other number it causes null reference exception error. Any help? thanks!
-Mike

Patched Deployments issue: "waiting for another installation to complete"

I have some percent of computers which runs into above state in monthly patch deployments. I could minimal information from execmgmr, udpatesdeployment.log,
CliSpy and Client Center etc tools but that doesn’t offer much help to nail down the issue completely. Have any of you dealt to resolve such issue successfully ? Is there any efficient way to handle this ?
It seems I have
DeploymentA, waiting for the completion of DeploymentB, which in turn waiting for the completion of
DeploymentC. Is there any better approach I could take to nail down and resolve the issue. One of my finding is, KB articles installs (SCCM R3, SCCM Asset Intelligence) causes these issue as they restart (upgrade sort of execution) the
agent during the execution, I need to confirm these
Vasu

Hi Vasu,
This issue can be caused by a deployment was previously deployed and was now deleted. This was because the clients finished installation
and wanted to notify the Server that it is done, but since the deployment was deleted, it couldn’t Notify its progress to the site server and the CCM_DeploymentTaskEx1 got stuck.
Please use the following scripts to delete the instance to test this issue.
strService = "CcmExec"
strComputer = "."
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\CCM\SoftwareUpdates\DeploymentAgent")
Set colWMISettings = objWMIService.ExecQuery("Select * from CCM_DeploymentTaskEx1")
For Each objWMISetting in colWMISettings
objWMISetting.AssignmentId = ""
objWMISetting.JobId = "{00000000-0000-0000-0000-000000000000}"
objWMISetting.Put_
Next
'Stop service
Set objWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objService = objWMI.Get("Win32_Service.Name='" & strService & "'")
objService.StopService()
WScript.Sleep 10000 ' Pause to allow service to stop
'Start service
Set objService = objWMI.Get("Win32_Service.Name='" & strService & "'")

Hp34970a read vi doesnot wait for scan to finish

hi all.... i am facing problem ..im tryin to read DC current values from two channels.. i modified the advanced scan vi example..
the read
vi is not waiting for the scan to finish.... i used trigger vi outside
a for loop and i want the readings to be taken for a number of times
which is equal to the trigger count.... i even placed a time delay
between the standard event vi and the read vi....the standard event
register vi has been set for operation complete bit. Yet the read vi is
not waiting.
so can anyone let me knw if the delay helps in waiting the read vi to finish the scan??
will the read vi give out the readings for each scan or will it just display random values??
im
posting the vi here... i kept the scan count to be 15 and scan-scan
interval as 1sec. ( so it implies that im using a timer source for
triggering) I used a time delay of 0.9secs in between standard event
register vi and the read vi.
i used a for loop insted of
a while loop coz i need the number of readings = scan count. i placed
the trigger vi outside the for loop.
can anyone have a look over this vi and help me out?

Now I placed a while loop around the standard event register vi and i am running it till i get a true in the bits set output. this time i checked the parameter'operation complete bit' instead of setting it. Only then i can see true value on the bit set output or else false.
The bit 1 is true after some time (after scanning is done), but the instrument is showing -410 error. This error actually says ' a command was received which sends data to the output buffer, but the ouput buffer contained data from previous command(previous data is not overwritten).The output buffer is cleared when power has been off or after a bus Device Clear.'
What should i do? Can you tell whether what i did is right? I atached the vi which has while loop around the standard event register vi.

Some more details will probably be required. The OS X version will help, as a start.
If you have the diagnostics DVD disk, boot that and see if there are any errors logged.
If this is OS X that's installed on a MacBook Air that you're using, then some of the usual triggers and approaches for resolving the still waiting for root device errors are discussed here. Have a look at that, and see if something in that sequence looks familiar, whether the PRAM reset or the safe boot helps or works here.
If there's any anti-malware, I/O accellerator, antivirus tools or similar installed, get rid of it. At least for testing.
There's a mention of "other OS" in your footer. If not OS X, what is the operating system in use here? If this is some other hardware or software involved, then the triggers for this error can vary. Widely.

Why "wait for operation complete" error ?
