How is the counter clock chosen?

[Peg]

I understand the the DAQCard6036 has two clocks for the counter, one is 20 MHz and the other is 100 kHz. When asking for a pulse train in terms of pulse width and frequency, how is the clock determined? Is this something I must specify, or does it happen automatically when using something like Generate Pulse Train.vi?
Thanks,
Peg

Hello Peg,

When performing a pulse train output, the timebase used is determined by NI-DAQmx automatically.  You do not have to explicitly set it.  If you would like to know what NI-DAQmx chooses for the master timebase and/or rate, you can use a property node.  It is a DAQmx Channel Property Node, and the properties are: Counter Output>>General Properties>>Counter Timebase>>Source, and Counter Output>>General Properties>>Counter Timebase>>Rate.
