Frame rate drops on 1410 and 1405 cards.

[Blue]

Hi-

I am using a 1410 and a 1405 card. 

I am experiencing a problem of dropped frame rates while using imaqGrab function.  I am putting this in a timer control ( just like hlGrab example provided with nivison) and get really high frame rates and then a drop to really low frame rates.  The drop seems to be at consistant intervals.  I have tried using each card independantly to isolate problem.  Happens with each card independatly.  I have tried using a buffer and not using a buffer.  Timer control on UIR is set to 0.000 for timer interval so should be happening as fast as possible.  Anyone have any ideas?

Hi  Blue,

How do you see the frame rate drop and how do you measure it? What is the expected frame rate in your application?

Thanks and have a great day.
