added some channels in random order under the 

“4-wire mdoe” topology.

Figure 27 Random channel scan sequence 

When using the driver, although the scan order of the channels does not 
necessarily match the order of adding channels, the data is automatically 
reordered  internally  by  the  driver,  so  the  order  of  the  data  of  each 
channel’s reading data will always be the same as the order of adding 
channels. 

5.2.2 ADC Timing Modes 

The ADC inside PCIe/PXIe-6301 has a built-in digital filter and multiple 
filter options. Filter options affect the data output rate and 50 Hz / 60 Hz 
rejection,  and  the  lower  the  ADC  conversion  rate,  the  better  the  noise 
rejection. 

The PCIe/PXIe-6301 driver provides a total of 6 ADC convesrion rates, 
from Level 0 to Level 5. Level 0 has the slowest conversion rate and best 
noise rejection. Level 5 has the fastest conversion rate and lower noise 
suppression performance. 

The reciprocal of the ADC conversion rate is the time required for each 
A/D conversion.
