Hi all,
I'm trying to use the matlab NI daq toolbox to send a predefined vector of TTL pulses (350 hz, 50% duty cycle) out of a USB-6212 DAQ analog out port. I am able to set the output rate accurately at 1khz, 10khz, etc.; however, these sampling rates can't accommodate accurate 350 hz signals at my specifications. I tried changing the rate to 35khz, it seems like system can't sample at that exact frequency, rather at 35026.2697 scans/second. Is there any way to work around this in with the daq and matlab?
Thanks!
Charles
