Notes:

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

To select a 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 top of the table.
