Figure 13 A / D conversion and sampling
The time required for each A/D conversion is controlled by the sampling rate level.
The minimum sampling rate of PCIe/PXIe-6301 is 0.275 S/s, and the maximum
sampling rate is 800 S/s. The actual maximum sampling rate can be set according to
the set rate grade and the number of channels added by each ADC for:
𝑀𝑎𝑥 𝑆𝑎𝑚𝑝𝑙𝑒 𝑅𝑎𝑡𝑒 =
Max Total Sample Rate
max (number of channels on one ADC)
