Lists of Maximum Number of Data Points per Channel
The table below shows the maximum number of data points per channel, per number of
measurement/computation channels to which data is saved. The maximum sampling
length is calculated by multiplying that number by the sampling interval.
For example, when acquiring display data on 3 measurement channels and 3
computation channels only, at a sampling interval of 4 seconds, look up the maximum
number of data points per channel value in table 1 that corresponds to 3 measurement
channels and 3 computation channels (333333) and input that value into the following
equation.
Max. sampling length = 33333 x 4 = 133332 seconds = approximately 37 hours
