Oscilloscope tektronix - ethernet

Bonjour,
je souhaite récupérer des fichiers de mesures depuis un oscilloscope tektronix vers un PC branché avec un câble ethernet avec Labview.
Je voudrais qu'à chaque fois que l'oscilloscope "trigge", mon PC enregistre le fichier de mesure.
Je vois deux moyens :
1) quand l'oscillo trigge il envoi le fichier mesure au PC par ethernet automatiquement (via réglage de l'oscillo);
2) l'oscillo envoie un signal au PC par ethernet indiquant qu'il a "triggé", Labview le capte et récupère le fichier par ethernet avec la fonction Read waveform faite pour ça.
Est-ce qu'un de ces deux moyens est réalisable?
Merci.

OK, j'ai mis en pièce jointe le VI tree du driver de mon oscillo.
J'ai regardé mais je ne pense pas que mon oscillo puisse renvoyer un signal de trig...
EDIT: autant pour moi
mon problème n'a pas lieu d'être puisque en réalité j'ai une autre info qui arrive sur mon PC via un autre équipement qui me permet de savoir ce que je cherche. Désolé du déragement.

I have a digital storage oscilloscope tektronix 2430,and an old style GPIB card (8 bit, ISA). How can I work with labVIEW?

My GPIB card is NI one, but it is 8 bit-ISA. I have LabVIEW (4.,5.1 and 6i version). I want to work with my digital storage oscilloscope Tektronix 2430. I need your experiences.

Hi there,
My suggestion is start try with "MAX" to communicate with your scope,
Download the driver for the scope from NI.com. And from there you can get started.
Good Luck and if you need any help, just post in this forum.

Want to get a hardcopy from the oscilloscope tds3034b through ethernet

i'd like to use labview to get a hardcopy from my oscilloscope tds3034b through ethernet,but after I sent out "hardcopy start" i can't receive any data from oscilloscope.I found some other people also have this issue,I don't know how to close it.wish you give me some suggestions.Thanks.

You are telling the hardcopy to go to a printer. See here for the code I used to get the screen shot and save it to a file on my computer instead of on the scope: http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/Screen-capture-of-Tektronix-MSO4104B-using-La...

Tektronix oscilloscope how to capture signal?

I have a Tektronix TDS 3014 oscilloscope. I connected the RS232 to a USB converter. Now I have it plugged into my laptop. How can I capture the signal of the oscillscope so I can analyze for future project?

Just some details to add to the check list
1) Have you turned the computer on
2) I suppose you want to use Labview. Have you installed that on your computer. And actually started the development environment.
Labview is like all software development system. It do have have what is called a learning curve. That mean you can not just install Labview and hope it will work like a magic wand. They have been fewer but some Labview sales people(with a used car salesman attitude) still like to tell the lie that you can take anybody directly from the street. And they will in 30 minutes understand how to create advanced Labview application. That is wrong. You actually have use Labview as a development system. In order to create working program. Also good questions draw good answers. So why do you not tell us what you have done so far, and why and how you struggle. As a start.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Strange behavior when using Labview to collect data from Tektronix tds8200 oscilloscope

I have hit a wall in trying to figure this one out. The problem I am having is that my program does not start the oscilloscope when it should.
I am using a Tektronix TDS8200 oscilloscope. My goal is to collect waveform data from the oscilloscope using Labview. My program first initializes and configures the oscilloscope; this part of the program runs fine.
The second part of the program begins the data aquisition using the 'tktds8k Start or Stop Aquisitions.vi' function, which is equivalent to pressing the Run button on the scope. The 'tktds8k Get Waveform.vi' function is then used and should ideally return the data, which I have connected to a waveform graph for visualization.
When I run my program, the first part executes without issue, but as soon as the program gets to the Get Waveform function, the Run button on the scope, which is green when running, turns off; the program then times out, and no data is collected.
Here's where it gets weird. I went through some debugging to try and figure this out, and I put breakpoints on both the Start and Get Waveform functions so that I could step through the later part of the program. The program continues through the Start function, and the Run button on the scope is green. The breakpoint for the Get Waveform function is reached, and when I press continue, the Run button turns off and then turns back on almost immediately; the data is collected, the waveform graph is displayed, and the program exits without an error.
I thought timing might be the issue, so I made the program wait as long as 5 seconds between the Start and Get Waveform functions, and that did not work. I also tried moving the Start function to before the configuration functions, and removing the Start function altogether; neither method worked.
Are there any thoughts on why the program works when I have the breakpoints enabled and doesn't when the breakpoints are disabled? I am sure that there is an easy fix, but I haven't been able to find a solution.
I have attached a pdf containg information on the Oscilloscope functions (tktds8k.pdf), and I have also attached my program.
Solved!

Thank you for the swift replies.
After Bill asked about the ID Query, I decided to try a few things that I had already gone over just to double check. I was suspspicious that timing was the source of the error. Using a timed while loop, I set the wait time to 10 seconds and got results. As it turns out, 5 seconds is not long enough, but 8 seconds is a sufficient wait time for the program to work. With the problem solved, I am still mystified as to why waiting 8 seconds is required.
I think that the oscilloscope must be given sufficient time to display the signal on-screen before the Start Aquistion or Get Waveform functions are used. With this logic in mind, the breakpoints were acting as a sort of wait, allowing the signal to be displayed before continuing through the program.
In response to Jeff, I am indeed using an external direct trigger. The hardware is sound, but apparently, my coding could use some work.
I have attached the modified code. I am certain that there is a more elegant solution to the timing than simply slapping a timed while loop on the code. Any suggestions?

Ethernet control of Tektronix scope using VISA

Hi,
I have got a new scope, TDS7104 and I want to remotely control it through the Ethernet port. Can anyone help me on how to do this using VISA. I haven't used VISA and I don't know how to start. Most of the examples I have seen are for GPIB and serial interface control. So, I am not clear as to how to use the Ethernet port to control the scope. With the scope, there is a TekVISA software but the examples they have given are for command line programming through C and I don't know how to do it in LabVIEW. Any example would be of great help.
Thanx & Regards,
Srini.

There is a great Knowledge Base article on our website that discusses how to control Ethernet instruments with NI-VISA found here.
While I am unfamiliar with using Tek-VISA, NI-VISA does have many cool features. Some of these features include the VISA Interactive Control where we can open VISA sessions on the fly without any programming, NI-Spy which allows us to log all NI-VISA driver calls helping us narrow down programming errors and behaviors, and seamless integration with Measurement and Automation Explorer allowing us to configure VISA and test our devices all in one place. More information on NI-VISA can be found at the following document links:
”NI-VISA and Tek-VISA; Which Do I Install?
”NI-VISA Product Information”
Hope that helps!

Hi. I am using a GPIB controlled Tektronix oscilloscope 11403. I am controlling it using Labview. I can extract the waveform trace through the program. But how can I save a hardcopy of that data in a spreadsheet?

Thank you very much.

If you want a text file in comma or tab separated data, then all you have to use is Write to Spreadsheet File.vi which will save either a 1D or 2D array array of data (i.e. 1 or 2 traces). If you want to write directly to Excel, you can modify the Write Table to Excel.vi example. There have been other Excel examples posted to the forum that you could do a search for.

Help needed with printer settings for wired ethernet connection

I'm hoping someone can help me with a network printing issue. I have a large format color laser printer (Tektronix Phaser) and since moving to OS 10.6 I can't figure out how to configure the printer so that the system sees it. I have a simple wired ethernet network with a couple of Macs and a couple of printers. All devices are connected via a switch. When using earlier OSs I was able to connect to the Phaser using Ethertalk. Obviously this is no longer supported and I can't figure out how to set the printer so the OS can see it. I have lots of options which can be turned on or off and in some cases set up in other ways: Ethertalk, IPX, Netware, TCP/IP, DNS, LPR, HTTP and remote internet printing, I've tried messing with these but the result is always the same--system doesn't see the printer. Currently Ethertalk is on, IPX and Netware are off, TCP/IP is on, DNS and LPR are on, as are AppSocket, HTTP, FTP and remote internet printing. I can change the IP address but no matter what address I've tried I cannot ping the printer. (I'm using a Gutenprint driver for this printer.)
I don't really know enough about all this to get anywhere and I haven't been able to find help anywhere even from tech friends. Xerox won't help me and neither will Apple. Any help would be appreciated. I can supply more detail on specifics where necessary. Thanks, Bob

Old Phaser models may becoming more and more difficult to use, but you can give this a try.
1. Configure the printer via front panel to use TCP/IP and enable DHCP if it's supported. If not then you will need to configure an IP address for the printer together with your local network's mask, and gateway IP address. Except for the first the others will be provided by opening Network preferences to see what those settings are. The printer's IP address needs to be set somewhere within the range of IP addresses your router provides locally.
2. You need the PPD file required for your printer. If you have the Phaser driver installer you can use it to install the PPD or you can extract the specific PPD from the installer package. This part is tricky because I don't know where you may find the driver now if you don't have the installer. The older installers can be accessed through the Finder by selecting the package then CTRL- or RIGHT-click and select Show Package Contents from the contextual menu. You can then rummage through the package to search for the PPD for your printer. Then navigate to the /Library/Printers/PPD/Contents/Resources/ folder and drop the PPD file inside.
3. Open Print & Fax preferences and click on Add [+] to add a new printer. Click on the IP icon in the toolbar. Select Line Printer Daemon - LPD from the Protocol drop down menu. Input the IP address you assigned the printer in the Address field. You can file in the optional fields that follow. Then from the Print Using drop down menu locate the listing for your printer and select it.

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.

Setting Up Labview 7.1 with Tektronix TDS3034B

Hi there, I'm a student intern trying to do some data acquisition with Labview 7.1. The scope I'm using is a Tektronix TDS 3034B, and it is connected through ethernet.

Can't install PPD for Tektronix (XEROX) Phaser 740...

I have a Phaser 740 over ethernet that I can talk to through a basic PostScript driver but I can't get any features like duplex and the color does not match completely. I went to the Xerox site, xerox is now the home of Phaser, and downloaded their installer. I can't open it, it opens in script editor. If anyone can help it would save me. Thanks!
Specs:
Tiger 10.4.10
Macbook Pro
Tektronix Phaser 740 Current Driver: Generic PostScript

Oh my, I thought I thought of everything... Appending the .app extension to it and changing the permissions to run read/write as user, totally worked. Xerox really needs to do something about this stupid error. Thank you so much, you saved me alot of time.
thank you, thank you, thank you..

Communication Tektronix Labview (PC)

Bonjour,
je bataille depuis des heures avec un oscilloscope tektronix. Je viens demander de l'aider car je n'ai jamais fait ça.
Je travaille sur un projet ou j'ai besoin de configurer les voix de mon oscilloscope et récupérer les mesures qu'il fait avec LabVIEW 2010 en ethernet.
L'oscilloscope que j'tilise est un tds5054b, mais l'oscilloscope qui sera utilisé avec mon application labview est un dpo7104c. (je ne peux pas programmer en utilisant celui là car mon service n'en a qu'un et il est utilisé par une autre personne pour l'instant)
J'ai installé tek visa et ni-visa.
Maintenant est-ce que quelqu'un pourrait m'aider en m'indiquant quelles fonctions il faut utiliser dans labview pour commnuniquer des valeur et en recevoir avec l'oscillo svp?
Par exemple mettre une échelle de 1sec/division ou 2V/div sur telle ou telle voix.
Je n'ai pas la chance de pouvoir faire une formation et je ne trouve rien sur le net qui m'aide. Est-ce qu'il faut utiliser les fonctions VISA-xx? (visa-read, visa-write?)
Je précise que la liaison ethernet fonctionne puisque j'ai configuré les adresses IP des deux PC (l'oscillo est un PC) et avec tekvisa et la macro excel associée je peux récupérer des printscreens par exemple.
Merci.
Résolu !
Accéder à la solution.

Bonjour Alstomtarbes,
Vous voudriez régler cet offset sur LV plutôt que sur votre Oscilloscope?
Quel type d'informations envoyez vous à votre oscilloscope? A quelle fréquence?
N'y a t'il pas un VI d'offset ou noeud de méthode dans votre palette de driver (cf PJ ex driver Agilent)
Avez vous des exemples fournis avec votre driver susceptible de vous aider?
Voici un VI qui pourrait vous aider. Il est disponible dans la palette: Waveform >> Analogique.
N'hésitez pas à prendre des captures d'écrans ou nous envoyer vos fichiers pour que nous cernions mieux votre problématique.
Cordialement.

Screen capture of Tektronix MSO4104B using LabVIEW

I am trying to acquire a screen capture from a Tektronix MSO4104B oscilloscope using LabVIEW. I currently am able to collect data from the device, and have a waveform displayed on my VI front panel. However for various reasons, our preference is to capture the actual screen shot from the scope.
I have reviewed the programmers reference for this device, and have made countless searches on Google for an answer, but haven't been able to find a solution. It appears that a few people have been able to accomplish this on OTHER Tek scopes by sending a hardcopy through the communications port (GPIB, USB, Ethernet, etc...) however according to the programmers reference for this particular device, it appears that it will only send a hard copy to an installed printer, rather than simply as a data stream to the port that can be read using VISA commands.
The other solution I have seen is to save the screen shot to a flash drive, then copy the file through the port to the PC. However, neither of these solutions seem to be available on this device...this is one of the most advanced scopes that Tek makes...I can't believe this is so difficult!? Please help!
Solved!
Go to Solution.

I used a TDS3000 series scope from Tek and had success using the Hardcopy command. Note that I used the GPIB. Here are the commands I used.
HARDC:PORT GPIB;
HARDC:INKS ON;
HARDC:FORM PNG;
HARDC START
I also had fun because I had to recieve the data in chunks since an entire png file could not be transfered in one chunk due to buffer limitations.

I am looking labview driver for Tektronix TLA704 logic analyzer

I need this labview driver desperately, I am very appreciated if you have it and courtesy me a copy.
Thanks

I did some looking around on the Tektronix web site.
Tek does not seem all that interested in supporting the
TLA704 in particular, or LabView(tm) for logic analyzers
at all. IMHO the Tek site sucks when you need to find
information in depth.
I looked through National Instruments site too. Now on this
site it was easy to find what I was looking for. Good job.
Developing a LabVIEW instrument driver for a logic analyzer
looks to be a non-trivial task for anything more involved than
starting a capture and waiting for the data to log. Depending
on the driver it could be real slow getting a load of data from
the logic analyzer.
It might be better to use the TLA programmatic interface
(TPI) to run the TLA704 by remote control over the Ethernet.
All the support for this comes with the analyzer software.
Though it's really painful to get it setup in Windows 98.
This way you could create a Windows program that runs
on your workstation to connect to the TLA704, set it up,
start a run, and download the data. Once the data is in
your workstation you can reformat for use by LabView.
I don't know that this would be easier than making a
LabVIEW instrument driver for a logic analyzer, but
at least all the software exists right now to control
the TLA704 remotely.
Charles.
I don't work for National Instruments,
or Tektronix or use LabView. But I use
logic analyzers way too much.

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.
