Each AI channel provides an independent signal path and ADC, enabling you to sampleall channels ModesThe NI 9224 supports high resolution, medium resolution, high speed, and medium speedtiming modes. High resolution timing mode optimizes noise and rejects power linefrequencies. Medium resolution timing mode has a higher sample rate when compared withhigh resolution, and also rejects power line frequencies. High speed timing mode optimizessample rate and signal bandwidth, whereas medium speed timing mode has lower noise whencompared to high speed timing 9224 SpecificationsThe following specifications are typical for the range -40 C to 70 C unless otherwise voltages are relative to the AI- signal on each channel unless otherwise Do not operate the NI 9224 in a manner not specified in this misuse can result in a hazard.
