Different Counter Outputs with different number of samples

[IngoH]

I´m using an 6602 Timing I/O Board and/or a MIO 6281. For timing control of our measurements I use different counters from both boards triggered by a Digital Out for synchronization. The counters are set to CO Pulse Time, implicit timing, digital triggered and finite sample mode.

Lets assume I use two Ctr´s from the 6602 board. My problem is when setting the number of samples from only one CTR to another value then the second I´m getting an error. The rest works perfect, I can use different starting delays, low or high times, only different sample amounts don´t work. It´s regardless if I use the Timing I/O or Multi I/O board.

For example:

                             _ _       _ _

Ctr 0 / 6602 _ _ |     |_ _|     |_ _  --> 2 samples

                             _ _

Ctr 1 / 6602 _ _ |     |_ _

Somebody any idea or advice?

Here is my currently used code, perhalps it helps you understanding the problem. Both are doing the same but one is a bit optimized. Hopefully someone can help.

Hi,

two counters are used for a fenite pulse generation. Please see the link below.

For example you could use Ctr0 and Ctr2.

If all solutions would be so simple, thanks!
