I do not expect to see a square wave. The external clock is synchronous to the data pulses so I should always see the maximum (flat top) of the negativ and positiv half-wave. That results in a triangle in the VI display, that's understood. I thought, that using external sample pulses is a purely hardware issue. That makes me wonder how a new driver can affect that.
The traditional was working fine. But now I ran into limitations with the 16 Mio odd maximum number of samples. The data is coming in bursts of some 20000 a time, so I was collecting the whole set in one read. If there is a way to do this in traditional I might do that. But first I'd like to know what is really going on. The 6115 is probably not a solution. We are almost ready for an alpha test of our machine. It's supposed to to become a low-cost machine. We'll switch to the 2-channel version anyway. So I guess the 6115 would blow our budget. Since you are located in Germany I might try to contact you directly. Gabi
