From the course: Data Acquisition with LabVIEW
Finite analog input
- [Instructor] While an on-demand software timed measurement may be useful for some applications, if you need to use a hardware timed acquisition mode to acquire samples faster and with more accurate timing, you'll need to configure the task using DAC MX timing VI. The timing VI should go after you create the virtual channels, but before starting the task. So I'll shift my code to the right to make some room for it, and I'll delete these wires between the create channel VI and the start VI. I'll go to the functions palette, measurement IO, DAC MX menu, and select the timing VI. Place it, and wire the task in error wires. This is another polymorphic VI, which has a few options for configuring some more advanced digital encounter tasks, but for the majority of applications, you'll simply need to use the default sample clock instance. Pressing control H to look at the context help, I see that there's only one required input…
