Hello,
I'm using NI-6602 to output two interleaving digital pulse trains. Each pulse is 200ns wide, and when one channel is low the other should be high.
I also want each pulse train to be available at two output connections, i.e., I export the signal from each pulse train to another connector.
The problem is that there's significant overlap with the pulse trains. A picture is attached where you can see four waveforms of the four pulse trains.
There is no ringing or anything, just timing delays. Everything comes from the onboard 80 MHz clock. What can I do to alleviate this?
My connector block is BNC-2121.
I'm attaching the vi source. Counters 0,1 and counters 2,3 produce the two pulse trains, respectively. at PFI 36 and PFI 28. (PFI 28 is connected to User 3 BNC).
The trains are exported to PFI 33 and 32, respectively.
The pulse trains are triggered through PFI 38.
Channels 1,2 on the scope are the original pulse trains. Channels 3,4 are their duals. Also the coalescence between Ch1 and Ch3 is not perfect as in Ch2 and Ch4.
Any help is appreciated.
Itay.
