which hardware do I need?

[superfunk]

Hi,

I would like to aquire a sine signal (15-50Volts) and output a TTL (0-5V) from the sine. I have found VIs to realize this but I am facing a hardware problem. I am a bit lost through all the PXI/PCI denominations and still don't know which one is suited for my needs. I have experience with other products of NI (Machine Vision for example) but I am a complete beginner with the acquisition of data.

Input :

Don't know yet the type of cable

Ouput:

The TTL signal should be sent through a BNC cable

Thanks all for your help

Hi,

If you go to the link http://www.ni.com/dataacquisition/f/, you can select a board with specific features (PCI, PXI or USB and voltage level you need).

For multifunction DAQ, the boards you need will be in the 62xx serie or 63xx series for PCI Express.

Best Regards
