Solution
DSA modules and some CM C series modules are not designed to support single point (either on-demand or hardware-timed) acquisition or generation.
If you select
On Demand (single point software-timed) timing with hardware with delta sigma ADC's, NI-DAQmx may throw
Error -200077: Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property. Some DSA modules will not throw an error, and instead will return a single sample from an acquisition running at the maximum supported sample rate of the module.
If hardware timed single-point timing is selected, NI-DAQmx will throw Error -200077 as seen above.
