Precise timing using hardware counter

[GRMAN]

Hello all, i am using a PCI-6259. I need to use this board to get time. I am already using one of the counters, there are two total. I tried using some of the timing vis, but software timing is too slow. I am looking to log time with data collection. Does anyone have any suggestions?. Any help is Greatly appreciated

GRMAN,

What exactly do you mean when you say:

Do you wish to synchronize it with an IRIG timing signal? This functionality is only supported in our PXI-6608. Are you trying to timestamp analog data? By using LabVIEW's waveform data type, you should have fairly accurate timing information. At least as accurate as the worst-case error of the oscillator on your 6259 - 50ppm. This, of course, is only relative time. Absolute time will only be as accurate as your PC clock. Please give us more information and we will be glad to help!

I am just trying to timestamp analog data, i am not using the waveform data type, is that what you suggest?.

GRMAN,

That is correct. If you use the waveform datatype, your first sample will be timestamped. The timestamp of subsequent samples will be inferred from this initial timestamp through the use of the sample clock rate.

Hope this helps,
