Notes:

* For the top span, the 3 dB bandwidth is 1.15 times span shown.

To select sample frequency for time domain data, first divide the desired sample
frequency by 2.56 to convert it to a measurement span. Then locate the closest
measurement span on this table and choose the corresponding sample frequency at
the top of the table.
