how to change sampling rate

[bvlgari]

hi,

i have some third-part AD/DA Card and i use it for signal processing. i have one simple loop to get values from output but always with the same sampling rate. how can i change that (from 1-15kHz)

thanx

It would help if you said what the third-party card is. Did the vendor provide a LabVIEW driver or a DLL? Have you contacted them on how to control their hardware?

it is 'quancom'-card (PDA16DAC4) (www.quancom.com www.quancom.de) and there is a library to control card via Labview. i can get data from output, i can set data to (AD/DA), but i dont know how to set sampling frequency in my loop in block sheme from labview.

thanx

I had a quick look at what they provide and the the LabVIEW VI (the one I think you would use) is nothing more than a bunch of DLL calls. I would hope that in their documentation, the DLL is described and then you would add a Call Library Function Node innto your VI with the appropriate parameters. Complaining to the vendor that they really haven't provided a very good LabVIEW dirver might get a response.
