Write commands to GPIB with precise timing

[cooler]

I would like to write a command to the GPIB card several times, the time interval between two writings must be very precise(<1ms). This time interval includes two parts, one is the time GPIB communicates with the instrument, another is the software delay time.Both are not precise enough.My idea is to hardware delay a time interval and at the begining of the delay, write a command to GPIB simultaneously.So the time GPIB communicates with the instrument is covered by the precise hardware delayed time.I wonder whether this is possible.Any ideas??
Thank you for your help.

Hi cooler,

with Windows in your neck it will not be possible to achieve what you want to do. But your problem sounds like you write once something to your GPIB-device and then this device should operate within 1ms a couple of times. What I do typically in these situations - I use a Function Generator in Burst mode and vary the Burst Rate and Burst Count. This Function Generator Triggers the GPIB-device on external Trigger input. This helps of course not in every case.
Hope that this idea is something for you.........
