synchronize analog and digital output

[wige]

Hello, I have a NI 6711 card with a BNC-2110. And I have problems to synchronize the analog output with the digital ones. When I turn on both I have a delay between them of ~50 ms. Is possible to synchronize both outputs? How I should work?

Thanks,

Emiliano.

Typically, for synchronization on the same card on the DAQ platform, you would want to ensure that all tasks are hardware timed, and using the same sample clock.

Most DAQ cards do not feature the Digital I/Os having their own hardware-timed sample clock, so you would usually always need at least an Analog I/O task, even if it is a dummy one.

See the following example, and it might work for you.
