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 LabVIEW RealTime you can use a 1 MHz timing source.
• You can use an NI plugin board (not an USB device), e. g. an M Series board, to generate the timing for a timed loop.

I hope that helps,
