continuous sampling a signal

[Martijn]

I want to continuously sample 8 analog inputs with my PCI6013. I only have VisualBasic (No Measurement Studio!).

The time of my measurement is not known, it can be a couple of hours, but it also can be just one hour. The sample rate is 2kHz. When i want to use continuously data aquisition, what do i have to do? I don't want to give a maximum amount of samples to be taken, because then the buffer will be too large (upto 1GByte!!!) and then the card stops when he has captured these maximum amount of amples.

Can anyone help me?

Martijn,

You will need to perform a continuous analog input operation and log the acquired data to file. Below, I have included links to both a tutorial and an example program that demonstrate how to accomplish this task in Visual Basic with the CWAI ActiveX control:

Good luck with your application.
