USB A/D-D/A conversion board

Hello.

This might not be topic on PLC-s. But this is the only forum I have found so far, that talks about the problems that are related to mine. Here is the deal. I writting my diploma on A/D D/A conversions. And The board I need, must meet the following requirements.

Sampling 1 KHz (time of the sampling should be max 1ms).
At least 1 Analog input and 1 Analog output. (The more the better).
Desktop configuration (not a PCI card or other mountable in PC)
Conection over USB!
A/D conversion at least 12 bit.
D/A conversion at least 10 bit.
Conversion board must have drivers for Delphi 5.

One of the boards is this one (but it does not have drivers for Deplhi)
www.quancom.de And the card is USB-AD8DAC2

Or maybe there is a way I could reach these requirements with some modifications or maybe converters like (USB to RS232).

So that is my problem, and if anyone can help me find what Im looking for I would be very grateful.

Thanks to all.

Hi,

I have one of these, is it fast enough for you?


delphi is OK and I can let you have some sample code if you need it.

I just bought one from Measurement Computing. I'm not sure if it has Delphi drivers, its worth an inquiry. http://www.measurementcomputing.com/

Here is one, although I don't know if it fully fits your requirements:

Or go to:

and do a search on USB.
