Using hardware delay to replace "wait (ms).vi"

[cooler]

I would like to write a command to GPIB several times with precise timing(<1ms). But the "wait (ms).vi" is not precise enough.Is it possible to use hardware delay to replace "wait (ms).vi" ??
I have 2 PCI-6713 and 1 PCI-6602
My OS is Win98
Thanks!!

Sure. Get an I/O box with an external SRQ (or is that RQS) input and hook up
a one millisecond clock to that input. You can also use the I/O box to then
retrigger the clock. There are lots of other ways to do it but you get the idea.

I couldn't understand what you mean...could you give a clearer explanation, or where could I find the reference?
Thank you for your help.

Hello;

Unfortunately, GPIB commands are Software timed, and there isn't a way to guarantee that precision since Windows manages all the tasks on your computer.
