Example Procedure for Filtering Data (Using Limits) During
Stats
1 Using the procedure in the previous sub-section titled "Example
Procedure for Easy Viewing of Stats," set up the Counter to display the
minimum risetime value of an input signal.

The Counter will now perform the statistical computations (that is,
standard deviation, mean, maximum, and minimum) on only those
measurements that are within the user-entered limits. The Counter then
displays the statistics you picked (minimum, in this case).
6 Press Stats key until USE: is displayed.
7 Press any one of the arrow keys to toggle to ALL MEAS state.
USE: ALL MEAS is displayed.
8 Press Run key.
The Counter will now perform the statistical computations (that is,
standard deviation, mean, maximum, and minimum) on all
measurements, whether they fall in or out of the user-entered limits.
The Counter then displays the statistic you picked (minimum, in this
case).
