Do I trigger the camera or the frame grabber?

[SectorEffector]

Hello 

I have an analog camera (Electrophysics model 7290A) and a frame grabber (NI PCI-1405).

I also have a pulse power supply with a laser connected to it.

What I want to do is trigger the camera in a way that it will take pictures synchronised with the pulse power supply.

Now, both the frame grabber (trig) and the camera (genlock in) have trigger inputs. Which trigger input do I use?

I am programming in Labview 8.6, do I need somekind of timing code to make sure the code is not slower then the trigger pulse?

If I lose some frames due to slow code, that is ok. But I need somekind of synchronisation, right?

I am using IMAQ Vision and I made sure the trigger signal from the power supply is compatible with both the camera en the frame grabber trigger input.

Hope you guys can help me!

Sincerely,

Heinen

Hi,

As soon as you use a framegrabber card it's better to trigger the card instead of the camera, because the framegrabber then also triggers the camera.

There are lots of examples for triggered image acquisition, just use the NI Examplefinder with the keyword "trigger".

Hope this helps,

Christian

Hello Heinen,

please take a look at the link below:

You will find different trigger configurations.

For analog cameras you need the imaq functions instead of the imaqdx functions.

But the procedure is the same.

kind regards,

Elmar
