If I Browse the DAQmx Channel node properties then do a search for "Timing", I get two Digitizer/ADC properties: "Timing Mode" and "Custom Timing Mode" but neither of them can be selected. What is it you're trying to achieve? I've been using DAQmx for 10 years or so and have never come across these.
Thank you for the quick response!
I was following this tutorial:
At 3:30, the speaker decides to add this DAQmx Channel because he observes his instrument is collecting & plotting data at a very slow rate?
Right click the property node,
Choose "Select Filter"
Select "Show All Attributes"
Your device may not support that property.
