Master timebase signal

[GretchenSkellyZimmer]

DAQ AO Series User Manual, page 5_9 states 'Master Timebase Signal is available as an output on the I/O connector, but you must use one or more counters to do so.' Doesn't say how to do this. I would like to have this timebase as an output. How do you do it?

Hello GretchenSkellyZimmer,

To output the Master Timebase Signal use the DAQmx Create Channel.vi and set it to the Counter Output-Pulse Generation Frequency setting of the polymorphic instance. Then set your DAQmx Timing.vi to the Implicit setting of the polymorphic instance. This will then allow you to choose the counter you want to use, the frequency you want to output, and the duty cycle you want to output.

There are examples that are shipped with LabVIEW 2013 that will be functional if you have one of the later version of DAQmx. They are located under Hardware Input and Output»Counter Output in the NI Example Finder.

DAQmx will take care of how many counters that will be needed automatically. The user will just have to specific one counter that is open for use.

Regards,
