Yokogawa DL850 Scope

[gleroy]

Bonjour à tous, 

Nous venons de recevoir une centrale d'acquisition Yokogawa DL850 et je souhaiterai la piloter via LabView.

J'ai pour cela, dans un premier temps téléchargé les drivers associés via le lien suivant (sachant que je travaille avec LabView 2016):

https://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=97D0868FF181418FE04400144F1EF...

Un technicien de Yokogawa m'a également conseillé d'installer un plugin supplémentaire via le lien suivant:

https://www.ni.com/en/support/downloads/dataplugins/download.yokogawa-dataplugin-for-yokogawa-wdf.ht...

Après plusieurs essais, j'arrive à communiquer avec l'oscilloscope via USB et je suis dans la capacité de configurer mes différentes échelles, activer ou désactiver plusieurs channel. Mon problème survient au moment où je veux récupérer ma courbe, j'ai un message d'erreur qui apparaît:

Code erreur : -1073807339

<ERR> YKDL850 Wait for Acquisition Complete.
Timeout expired before operation completed.

Avez-vous une idée de comment je peux régler ce problème ?

Je vous joins le VI avec lequel je travaille

Merci par avance

You are in the wrong board, i notified an admin to move your post to the French one.

Sorry, I tried to explain my problem in english.

We have just bought a new acquisition centrale Yokogawa DL850 and I would like to manage it by LabView.

So, first of all, I download the scope’s drivers from the following link (I am working with LabView 2016):

https://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=97D0868FF181418FE04400144F1EF...

A technician from Yokogawa advised me to install another plug in from the following link:

https://www.ni.com/en/support/downloads/dataplugins/download.yokogawa-dataplugin-for-yokogawa-wdf.ht...

After several tests, I’m able to communicate with the scope via USB and I’m able to configurate different parameters as for example the scales (volt/div, time/div) and enable or disable the channel. The problem happened when I would watch the waveform on LabView, and the following error message appears:

Error : -1073807339

<ERR> YKDL850 Wait for Acquisition Complete.
Timeout expired before operation completed

Do you have any idea to solve this problem?

You can find the VI in the french message

Thanks

i guess the frame where you have the wait is the one, where the error message originates.

try to insert a frame before and move the "wait" in this new frame.

with parallel execution, you never know what is running in which order.

this would at least make sure, you are waiting before reading.

then try to increase the wait time, perhaps that will solve your timeout error

Does the waveform appear on the scope screen? My first guess would be that you haven't configured a trigger, and you didn't use the autoset, so perhaps it is waiting for some trigger which never arrives - hence the timeout.

Hi,

Did you already tried one of the examples that are shipped with the driver ?

The waveform appears on the scope screen and about the trigger I configured it as automatic

So I thought that it didn't need a trigger to start the acquisition.

Hi,

I tried different examples but every time I receive the same error message.

I misunderstand because I can see the waveform on the scope screen but not on Labview

Strange I used the DL-850 without any problems.

Which error do you get. The same as in the previous post ?

[cbutcher]

When you configure the timebase, what value do you set? Is it possible that the timeout (10s by default) is shorter than the total time (probably 10x the timebase) for a waveform, and so the acquisition times out before finishing reading?

If so, try setting a longer timeout.
