PCIe/PXIe-6301
’s 32 channels are grouped by 4 banks, each having 8 channels. The
sampling rate per channel must be divided by the sampling rate per bank.
The sample rate parameters are used by PCIe/PXIe-6301 driver software to select the
internal ADC Timing Mode which ultimate determines how fast the measurement
values are being returned.
