PXIe-5433 missing spec of minimum wfrm length while looping in scripts

[Henrik_Volkers]

Hi, 

I use a 5433 in script mode , with 400MS/S ,  myCarrier is 10 sample, myPulse some 100k sample .., no marker

script is quite simple:

script myScript
repeat forever
Repeat until scriptTrigger0
generate myCarrier
end Repeat
generate myPulse
end repeat
end script

but I always get an  Error -1074101613:

Device data underflow. The device was not able to move data fast enough to keep up with the sample rate.
Run the operation at a lower sample rate, or look for the following in the active script: markers too close together, waveforms too small, waits too short, or subsets too small.

Seems that there is some sort of minimum loop time..

Where is the spec telling me what is possible?

BTW about 60% of the online manual links give server errors ....
