export data waveform chart problem

[Sid05]

Well...sorry! The subject line matched my issue and so just replied. I am new to these forums. Nevermind, I will create a new one henceforth!

Getting to the issue, yes I am using a waveform chart. I am using Labview signal express for my work. The waveform chart history length has been set to a very large number (1e6). The update mode is set to default (strip chart). 

Also, instead of dragging the chart to excel (where I get 1 sec worth of data), when I right click and export the data to excel, I get no waveform data, beyond the header information. 

Any thoughts?

sorry, no idea..I never used signal express, in simple LabView VI application the export feature works (perfectly for older Excell, and with some bug for excel 2010)

Would you mind sharing your VI with me or point me to similar ones? I only need to acquire/view Voltage signal from a sensor and also capture the data on excel. Thank you very much for your assistance.

I do not have labview at home, so i cannot give you the link right now. But if you open LabView, there you can go to "find examples", and there you will find very clear and simple VIs including some explanation.

Another possibility (but i never used signalexpress) i guess is that, you can generate LabView VI code from you Signal Express project. Maybe the export data feature will work in this way?

Anyhow, LabView is very nice and useful, I suggest to learn some basics, there are many tutorials, and built in examples...

okey, I have reached my lab PC via remote desktop, so here we are:

open labview, and go to "Help" --> "Find examples..."

Here you go to "hardware input and output", and choose what type of way you want to use your sensor, for example your device is DAQmx ready, so you go there. Choose "analog measurements", and "Voltage". And you should see now many nice examples...

Thank you so much for your prompt responses. 

I am on Labview 2011. Under Hardware I/O, I don't see 'analog measurements' and voltage. I see GPIB, General etc. 

[Blokk]

What do you use to measure voltage? Can you give me the name of the device?

[Sid05]

I have a USB DAQ 6009. 

[Sid05]

That is the A/D. I am using an amperostat to get the analog signal.

this is what you need to read:

Also you need to install the newest DAQmx driver package (i think if you have bought your USB device, it comes with the driver CD).

So there should be many examples under the Help--> "Find examples" as i wrote before, you have to find DAQmx --> analog measurements... (see attachment)

Or you can use the above link as a starting point.
