SignalExpress with DSA70404B oscilloscope

[slele]

Hello,

I am very new to LabVIEW and SignalExpress and I have a few basic questions.

I want to log data from my DSA70404B oscilloscope through my PC (Windows 7 running on it) in order to calculate certain time intervals.

I don't have the GPIB or USB cables and so I am using an ethernet cross cable between the scope and the computer with manual ip settings.

Is it possible to view the scope waveforms on SignalExpress and carry out data recording using such an ethernet connection? My scope wasn't listed on the devices list when I opened SignalExpress. Is there any additional steps that I need to take in order to achieve communication between the oscilloscope and my computer?

Hi slele,

It won't show up as a device and you need to create a SignalExpress plugin in LabVIEW to communicate with the device.

Here is a link with more information:

Hope this helps!

Hello,

Thanks for your reply.

I did try creating a plugin. I still get an error that the vi might be broken inside SignalExpress.

In LabVIEW, I cannot successfully run the vi because of the VISA resources error I get (which I have posted in another board, attaching the screen capture again here)

I have no clue how to resolve this. Could you please throw some light on this? It would really be of great help to me.

Thanks.

Hi slele,

Usually means the instrument can't be connected to remotely. Perhaps the instrument has been disconnected from the network or the IP address changed?

Check the settings on the instrument to make sure the IP address matches what you have in MAX.

Thanks!
