Short Name: AI.ADCTimingMode

Property of DAQmx Channel

Specifies the ADC timing mode, controlling the tradeoff between speed and effective resolution. Some ADC timing modes provide increased powerline noise rejection. On devices that have an AI Convert clock, this setting affects both the maximum and default values for AIConv.Rate. You must use the same ADC timing mode for all channels on a device, but you can use different ADC timing modes for different devices in the same task.

Custom (10137) Use AI.ADCCustomTimingMode to specify a custom value controlling the tradeoff between speed and resolution.
High Resolution (10195) Increases resolution and noise rejection while decreasing conversion rate.
High Speed (14712) Increases conversion rate while decreasing resolution.
Best 50 Hz Rejection (14713) Improves 50 Hz noise rejection while decreasing noise rejection at other frequencies.
Best 60 Hz Rejection (14714) Improves 60 Hz noise rejection while decreasing noise rejection at other frequencies.
Automatic (16097) Uses the most appropriate supported timing mode based on the Sample Clock Rate.
