Can USB-6251 generate very short digital/analog pulse?

[jerryguo]

I'm using USB-6251 to generate a voltage pulse with a duration of 1us, is this doable? Thanks in advance and any quick reply would be greatly appreciated. I'll wait online.

Hi,

I hope you are doing fine.In order to help you can you please answer the following questions

1) What version of LabView are you using ?

2) What operating system are you using ?

3)How are you setting up the equipment to generate the voltage at the moment.

below is the specification document for the 6521, that might help you as well.

Thanks Nisar, right now I'm using labview 8.5 under windows xp OS, and I simply connect the USB DAQ card to my computer and use the analog output port on the DAQ card to generate the pulse. I read from the manual that the analog output has a timing resolution of 50ns, so I figure it might work. The problem is I don't know which function block I should use to generate such short pulse?

Hi,

I hope you are doing fine.Can you please give me a brief description of what you are developing, in particular can you further clarify your description of the function block. Also if you have started programming can you send me your VI or its screen shot.

Best regards,
