Hello, I am using a Multi I/O DAQ Card (6110 S-Series). I have to generate two synchron Pulstrains from which I can change the Frequency in a loop. My problem is I have one task with two channels. I get them synchronized by Creating the two channels and linking them together getting one task but if I want to change the Pulsefrequency (high ticks / low ticks) I cant do it with the DAQmx write VI because this only works if I have one channel. Actually my signal should look like this: --- --- - ------- ------- --- --- ----- ------- ------ The fist signal is high for some time than there is a break for exactly 2
