Signal express tektronix

I'm using Labview signal express tektronix edition and connecting my tektronix tds3054B to it by ethernet. When I typed in my oscilloscope ip address to the program, it can't acquire for the signal. I think I have all the required driver and VISA. Here is the error that it gave when I tried to connect:
Error -1073807298 occurred at Property Node (arg 1) in tek_subTek3kScopeInitializeData.vi->tek_Tek3kScopeInvokeCommand.vi:1
Possible reason(s):
Primary Error: (Hex 0xBFFF003E) Could not perform operation because of I/O error.
Elaboration: Attribute: TKDS30XX_ATTR_SLEW_DELTA_TIME
Any idea how to solve this error?
Thanks,

Hi,
I can see my instrument listed under MAX so that means I can communicate successfully. However, when I ran the Signal Express Tektronix edition, I cannot see the signal on my computer. I have posted screenshots I think they might be useful. When I clicked run, the program is just "waiting for trigger" but I can't see anything on dataview. Maybe I set up the trigger wrong? Please let me know if there is anything I should try.

Journal d'enregistrement avec Signal Express et oscillo Tektronix MSO4034 : les 4 voies dans un même fichier?

Bonjour,
Je réalise des enregistrements des 4 voies analogiques d'un d'un oscillo Tektronix MSO4034 avec Signal Express 2.5. Les données sont bien enregistrées dans des fichiers TDMS et txt, mais il y a 1 fichier par voie.
J'aurai préféré avoir les données des 4 voies dans un seul et même fichier, mais je ne trouve pas l'option qui permet cela : est-ce possible?
Merci d'avance pour vos réponses.

Bonjour,
Merci pour votre réponse rapide.
Afin de contourner le problème, j'ai téléchargé le driver suivant:
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=6E23DB10D9FC2B05E04400144FB7D2...
Ca marche plutot bien, avec un vi d'exemple fournis j'arrive à faire l'acquisition d'une voie de mon oscillo. A priori, il ne resterai plus qu'à enregistrer les données de la waveform dans un fichier txt comme je le souhaite.
Seulement, après un essai du vi d'exemple permettant d'acquérir plusieurs voies, les voies sont visiblement acquises l'une après l'autre. En cablant la voie 1 et la voie 2 de mon oscillo sur un meme signal de sortie d'un GBF, les signaux acquis sont décalés temporellement (décalés sur mon graphe Labview, pas à l'écran de mon oscillo). Est-il possible d'acquérir simultanément (j'entend par simultanément 1 valeur par voie à chaque n*dt) les 4 voies de l'oscillo?
Merci d'avance.

Interface to HP34970A with Signal Express

Hello,
I am trying to interface an Agilent HP 34970A using a demo version of Signal Express 1.2. I installed the ivi-com driver version 1.0.0.4 from Agilent. When I go through "add step/IVI DMM Acquire" there is no instrument driver available in the pull down menu. Is there something I should do in MAX ? I have the same issue with a scope TDS 7104 using Tektronix ivi driver 2.5.
Thanks for your help.
Rob

Rob,
Thank you for contacting National Instruments.
It sounds like there is a problem with the installation of the instrument drivers. There is a knowledgebase that walks you through the installation of IVI drivers with SignalExpress. Also National Instruments provides instrument drivers for Tektronix TDS 7104 and Agilent Technologies 34970A.
The drivers that you have currently installed should work, but the National Instruments instrument drivers for the two devices could be more likely to install properly. Also please step through the associated knowledgebase.
I hope this helps. Please let me know if you still are having the same issue. Have a great day!

Signal express LE on host machine

Hi,
I'm having a problem with an application I built.
I want to control my tektronix power supply with Signalexpress LE on a host machine.
LabVIEW is not installed on this machine but I have installed LabVIEW run-time.
All others application I built work fine on my host machine.
I barely can't control my power supply on this host machine...
My application is fine because it's working on my development machine.
Is there any software to install on a host machione to make my application work?
Thank you!
Nicocmd

Hi nicocmd,
Just to make sure I understand the case. You built a project that communicates with a Tektronix power supply in Signal Express. Now you want to deploy that project to another computer that only has the run-time engine installed? What do you mean by barely can control?
Best Regards,

PWS4000 and Signal Express

Hi,
I recently get a PWS4305 power supply, I installed SignalExpress as recommended.
I just want to generate a signal and control the PWS with labview.
So I selected 'add step' ->'tektronix'->'generate a signal' -> 'tektronik power supply'.
Here, a display shows two line, one for the voltage, another one for the current.
I can find my PWS in the VISA Ressource. But how can I generate a signal ?
Thank you

egfrgr,
I believe you may need to download and install the following SignalExpress step before using your PWS4305:
LabVIEW SignalExpress Step for PWS4000 V2.0.0
Please read through the release notes for installation and usage instructions, copied here for reference.
Steps for using the Steps:
1. Run the setup.exe provided as part of Step Installer.
2. Open the LabVIEW SignalExpress Tektronix Edition software.
3. Click "Add Step" in the LabVIEW SignalExpress Tektronix Edition main menu and select Tektronix-> Generate Signals -> select your instrument series.
4. The Step appears in the Project View of Signal Express and is ready to be used.
5. Connect the instrument to your PC.
Note: You can check the connection to your Instrument using the Measurement & Automation Explorer or the TekVISA OpenChoice Instrument Manager.
6. Next, select the device in the LabVIEW SignalExpress step by selecting the "VISA Resource" tab and selecting the device in the "VISA Resource Name" drop down list. At this point, the interface is ready for use.

VIプログラム上でsignal expressの信号が読み取れず.エラーコード(0)が出てくる

横浜国立大学　山本研の仲丸と申します。
私は添付のプログラムでオシロスコープTDS2004Cから波形データを読み取りそれをエクセルファイルにするというプログラムを作成したのですが、プログラムを回す時にsignal expressからの信号が来ずエラーが出てしまいます。
signal expressを軌道して波形データを読み取る際には波形を見る事は出来るのですがプログラムを回す時にsignal expressからの信号が来ないためか困っています。
どのようにすればいいのか済みませんが教えていただけないでしょうか？
ちなみにlabviewは2009年度版を用いています。
PCとオシロスコープとの接続にはUSBを用いています。
追記
依然、色々いじっていたらプログラムを回すことはたまに出来たのですが何でできたのかその理由がわかっていない状況です。

Signal Express自体からはデータが読めているのでしょうか？
Signal Expressのツール⇒コード生成⇒LabVIEWダイアグラム　からVIを作成したものに
問題が発生しているということになりますでしょうか？

TDS2024B Signal Express 2.5 problem

Hello.
I have a problem with SignalExpress 2.5, I have installed SignalExpress 2.5 to use it with my Tektronix TDS2024B, but it does not detect the scope in all...
I have install the package tktds1k2k_setup.exe too... but no way... in "add step" i can not see the Tektronix Label as in my old SignalExpress Tektronix edition (installed in other PC)
How can i add the scope to be able to acquire signals?
Thank you!

Report generation toolkit and signal express user step : problem of closing reference in "Stop" event

Hi all,
I'm trying to make a package of Vis to easily make Excel reports with Signal Express. I'm working on LabVIEW 8.2.1.
I'm using the report generation toolkit, so I build a .llb from my project which contains all the hierarchy of my steps, but also the hierarchy of dynamic VIs called.
I have made some steps, like "Open Workbook", "Write Data", etc.
My steps run well, excepts one step : "Close Workbook".
If my "Close Workbook" step is firing on "Run" Signal Express event, I have no error, so my reference is properly closed.
But if my "Close Workbook" step is firing on "Stop" Signal Express event, I have an error "1", from "Generate Report Objectrepository.vi".
I feel that I'm trying to use a reference which has been killed in the "Stop" step...
I would like to know what exactly do Signal Express on "Stop" event and why my close function does'nt run well.
Thanks,
Callahan

Hi Callahan,
SignalExpress (SE for short) does the following on the Stop event:
1. Takes the list of parameters that SE found on your VI's connector pane, and sets the values that the user set from the "Run LabVIEW VI" configuration page, if any.
2. Then tells the VI that SE is running the Stop event by setting the Enum found on your VI's front panel. This in turn should produce some boolean values telling your VI to execute the Stop case.
3. The VI is then run, with those values and states.
4. SE checks to see if any errors where returned.
5. Since this is the Stop event, SE releases the reference to the VI which it possesses.
Questions for you would be, is the reference to your Workbook linked to a control on your connector pane, or held in a uninitialized Shift Register. If it's held in a Shift Register, SE would not be aware of it, and would not be able to affect that reference.
Hope that helps. Feel free to post your LLB if it doesn't.

Can I save data in a snapshot from signal express 2013 LE?

Can I save data (in txt or excel format) from a snapshot from signal express 2013 LE? My data buffer is too larege to export to excel. When I try to take a snapshot, I do not see any data. Are snapshots supported in the LE mode? This is the free version that comes with the USB 6009 ADC.

Yes, the snapshot function is available for SignalExpress 2013 LE. Does the snapshot function as intended when you try other projects?

How do I get channel names written into a logged ascii file in Signal Express

Hi there,
This maybe a rookie question but I am a relative rookie to this software, and I hope it has an easy fix!
Background:
Take a load of analogue inputs from a DAQ device into Signal Express, first thing that hits me is that unlike labVIEW you cannot right click in the channel configuration window and change the name from say... Dev2_ai0 to Air Pressure? I feel that if this was possible then I would overcome my problem? anyway I can't so onwards...
I goto the DAQmx Acquire window on the top left and can right click and rename the channel, which is great... however this does not translate to the logged data as I get the ai0 channel names across the top of the columns and not the names that I have put in.
Is there anyway of getting data like the attached snippet?
Many thanks for your help in advance.

Channel names.gif ‏4 KB

Hi Dan,
Thanks for the reply, that has certainly fixed my issue as I wasn't expanding the channel and selecting the channel that I had renamed.
One last thing though:
I now not only get the individual channel name but the prefix for the DAQmx Aquire, for instance I get the Input of Braketest and then the channels under the input data.
It looks a bit like this....
Braketest - Front Pres
Braketest - Rear Pres
Braketest - FR Temp
Braketest - FL Temp
etc etc...
Now all of the channel names at the top of the columns have this long name. Can this be rectified? can I remove the "Braketest" bit?
By the way I am saving it as an ASCII so that I can read it in excel.
Many thanks, Neil.

Using Signal Express VI for DAQmx, timing & file size issues

I am using a Signal Express VI with my DAQmx. Long story short, my DAQmx VI's don't work in LV 8.6 (possibly IT installation error). I have a few issues (I'm a beginner so be easy).
First, I'm confused on how to get the timing correct. I am trying to read a 100 samples (2 channels) average them and repeat this at 30Hz and record this data.
Second, everytime I open the Signal Express VI (in my block diagram) and change sampling for example, click OK, then save my VI before running my program. I noticed the file on disk increased in size by the megabytes! All I changed were the sampling settings.
I appreciate any input, thanks in advance!

To your first concern, it sounds like DAQmx was installed before LabVIEW. Just reinstall DAQmx and it will work fine in LabVIEW.
For you second concern. To get 100 Samples at 30 Hz, you will need to change your channel setup in signal express. You will need Continuous Aquisition, with 100 Samples to Read at 3000 Hz. Then you code should work as expected.

Populating the Signal Express Category on the Functions Palette

LV Functions Palette.PNG ‏14 KB

Hi Ewan,
Uninstalling and reinstalling in the right order would ensure that everything was properly associated. However, I don't think that should be necessary yet in your situation. Please go to Control Panel > Programs and Features > National Instruments Software to see the full list of National Instruments software you have installed. From here you should be able to select any individual installation from the list and select "Repair". Instead of just seeing that something is already installed and exiting, this should go through the installation and check for corruption. As well, this should add the correct associations if they were currently missed due to the order of installation.
Please try running a repair of SignalExpress 2013 and restarting your computer, then check to see if the functions palette in LabVIEW is fully populated.
Thanks!

LEGO Mindstorms 2.0 crashes at startup when LabView Signal Express is installed first

When NI Circuit Design Suite Education Edition is installed first in a computer and the LEGO Mindstorms software second, the LEGO Mindstorms software doesn't work, it reports the following:
Error: A required file is broken
Possible Solutions: Reinstall the LEGO Mindstorms NXT Driver (tried but doesn't work)
Error code: 1003
Ordinal not found
The ordinal 18 could not be located in the dynamic link library NIVISV32.dll
Error loading "fantom.dll"
The operating system can not run %1
On other computers the LEGO software starts running, it displays part of the initial screen and then a small window opens saying that the Mindstorms software has has an error and that it will close. The previous report doesn't show.
If LabView Signal Express is uninstalled and then the LEGO software reinstalled, the LEGO software works.
I've dowloaded and installed new and old versions of the NIVISV32.dll and this doesn't correct the problem. I went as far as version 4.20 of the dll because it is dated in 2007 and the dll file installed by the LEGO software when it works is also dated 2007, but if I install the dll without uninstalling LabView Signal Express, the LEGO software continues not working.
Please advice how to correct this problem without having to uninstall LabView Signal Express first. If the LEGO software is installed first, is LabView Signal Express going to use and not to replace the old 2007 version of the dll installed by the LEGO software? Is there any LEGO software update that corrects this problem?
I repeat: I know a solution is to uninstall LabView Signal Express, install LEGO Mindstorms and then reinstall LabView Signal Express but I have 60 computers already cloned and deployed with this problem, so I don't want to go to this long process to fix the problem. The computers are using Windows 7 and problems happen on both the 32 and 64 bits versions of Windows 7.
Any ideas???
Solved!
Go to Solution.

I couldn't reproduce the error either, but in our x86 computers this problem appeared after several months; we used LEGO Mindstorms last time in Summer 2011 without any problems and just three weeks ago when we were checking the computer for our Summer 2012 classes if when we noticed the problem. I’m still going to try to reproduce the error in an x64 computer where the problem appeared immediately.
Anyway, I’m attaching a word file with images of captured screens where you can see the error reports generated by LEGO Mindstorms and a series of steps uninstalling and reinstalling these program plus LabVIEW, until LEGO Mindstorms finally works after having uninstalled all traces of LabVIEW.
Images can be expanded and zoomed in to a better view of the details and if I can reproduce the problem in an x64 computer I’ll let you know.
Please see if you can find out something based on the images I’m sending.
Thank you.

Export to Excel problem in Signal Express 2012

Equipment used: PXIE-8102 CELERON T3100 1.9GHZ Controller Windows 7, PXIE-1071 4 Slot Chassis, PXIE-4140 4-Channel SMU 1.7.5 version.
I am using Signal Express 2012 and the SMU to plot the I/V characteristics of FET and other active devices. I am able to obtain the anticipated curve traced results but I am not able to Export the data to Excel directly from the Data View using the Microsoft Excel option. The error message is: Data could not be sent to Microsoft Excel. Please ensure you have a properly licensed version of Microsoft Excel. See attachment.
We have checked our version of Microsoft Office, it is Professional Plus and has the correct volume license so it does not revert to a home or student version.
I have been able to use the Export to Excel function directly from the Dataview when I was using one of the waveform tutorials supplied with Signal Express so I suspect it is a function of the SMU.
In conversations with an NI support engineer he felt it may be a problem with "an active x call is just not seeing the license for some reason", his suggestion is to drag the data into Excel rather than use the Data view tab. Because the SMU is being used in a production environment it is not really appropriate to have the operator work at this level so I would rather figure a way to have the data exported using the Data View tab.
Anyway please can you let me know if there are any known work around for this issue.
Thank you
