I would like to use the C Series module (which has "High-resolution mode" and "High-speed mode") in high-resolution mode. I can't find a function to select one or the other mode.

Several modules such as the NI 9207, NI 9208, NI 9209, NI 9212, NI 9213, NI USB-9213, NI 9214, NI 9216, NI 9217, NI 9219, NI 9224, NI 9226, NI 9228, and NI 9775, can be configured for high-speed or high-resolution measurements. That you will be able to select an exact mode, the following steps should be followed:

1. Go to the Block Diagram.
2. From the Function palette, go to Measurement I/O >> NI DAQmx, and select Channel Node from the list.
3. Click on Property and navigate to AI.ADCTimingMode by selecting Analog Input >> General Properties >> Digitizer/ADC >> Timing Mode.
4. Right-click on AI.ADCTimingMode and select Change To >> Write.
5. Right-click the input of AI.ADCTimingMode and select Create Constant.

So, now you can select the exact mode that you want.
