how to simulate time step less than millisecond (ms)?

[Coffeelox]

hi,
 
I am trying to simulate a data source with period less than 1 ms. and now I am using LabView 8.5.1, and I found "wait unitl next ms multiple", it seems the smallest time resolution is 1ms. How can I adjust to get less than 1 ms running?
 
Thanks...

This question should be better posted to the LabVIEW forum instead of the Motion Control forum, but anyway. The fastest timing source provided by Windows is 1 kHz That's the reason why you can't use a faster software timing in LabVIEW, but there are some options:- With <a href="http://www.ni.com/realtime/" target="_blank">LabVIEW RealTime</a> you can use a 1 MHz timing source.
- You can use an NI plugin board (not an USB device), e. g. an <a href="http://www.ni.com/dataacquisition/mseries.htm" target="_blank">M-Series board</a>, to generate the timing for a <a href="http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/con_timed_structures/#Timed_Loop_Structure" target="_blank">timed loop.</a>
