how to measure time duration between two rising edage from two signals

[tj33]

We are trying to calculate the time between two rising edages from two different signals respectively using LabView 7 Express. Anyone can help us for this? Thanks.

Can you be more specific about what platform you are running on (PCI, PXI, cRIO, etc.) and what specific hardware you have for performing the signal inputs?

Thanks.

Thanks Christian for your reply,

We try to use two rising edges from two analog inputs from Measurement Computing USB-1408FS board to calculate time duration between these two edges in LabView which runs on Windows XP.

Hello. 

In searching Measurement Computing's website, they provide a driver for their DAQ boards which includes VI's for use in LabVIEW.  However, this is not freely downloadable so I believe the help that I can offer you will be limited.  I invite you to go to their website at the following address where you probably will receive more assistance.
