Mathias,

I would be happy to help you come up with possible solutions for your application. For me to do this, I need for you to describe in more detail your application: the signals you are acquiring, the sampling rate you want to use, what are the phenomenons that you want to detect, etc.

Hope to hear soon from you,

Holy cow, that's the nicest answer I think I've ever seen! If every forum was this pleasant, a lot more would be acomplished (where's the spell check on this forum?). Cheers to Claudia!

Agreed!

That's one of the reasons I subscribe to Claudia.

What's more she knows what she is talking about.

Hello Claudia,

sorry about my delay, but i´m still on holiday....

I try to explain...

I have to test a DVD player, whether the playback of an moving image is ok
or not. If it is not ok, then there are normally blocks (blocking noise)on
the monitor.
Measuring of the digital-datastream is not possible, so i have to test the
analog video signal (CVBS).

Hardware available: scopecard 5112, grabber 1411

Thanx for your help!!!

Greetings
Matthias
