1D-array Video signal

[shoneill]

I'm a relative newbie when it comes to hardware triggering, so here's what might be a trivial question....

I have a CMOS chip which delivers a 1D video signal which I want to interface with an old MIO-16E card.

I have a base clock (up to 800kHz) which I will be supplying with the card.  I have a start integration time trigger, which will also be supplied by the card.

I then read a video signal at a frequency of base-clock / 4.  Each single read is accompanied by a trigger from the sensor (duration 1 base clock pulse), so theoretically I could use a hardware-triggered analog in, right?  The thing is that I want this step to be repeated N times (somewhere between 128 and 1024 times) until an EOS signal is registered on another line.

I have read up on post- and pre-triggered measurements and I think I need to implement a start and stop trigger and then simply scan at the base clock frequency with the associated array handling afterwards.

Is there an easier way to do this, like Read at trigger A until trigger B?  Can I perform multiple single-point measurements with a start trigger until the EOS signal is sent (stop trigger)?

Thanks.

There is an example for this, but it works with daqmx only (not compatible to older cards and LabView 6.1):

Here is an example fro traditional daq that should work:

Hope this helps!

That's fantastic,

Thanks for the help.

I'll give it a try.
