Example Procedure for Computing Stats
For demonstration purposes, let’s say you need to know the mean (average) and
minimum frequency values of a signal. Also, you want the Counter to make 20
measurements before it performs these statistical computations.
Perform the following procedure to accomplish this task.
1 Connect the signal to channel 1 input, and press Freq Ch 1 key.
2 Press Stats key until N: is displayed.
N: 100 is displayed (100 is the default value).
3 Set N to 20 (since you want the Counter to make 20 measurements before
computing the mean and minimum values) by pressing the appropriate arrow
keys.
N: 20 is displayed.
4 Press Enter key.
NOTE BE SURE to press the Enter key to complete numeric entry.
The Counter is now set to make 20 measurements before computing statistics.
5 Press Stats key until
SHOW:
is displayed.
6 Press any one of the arrow keys until
SHOW: MEAN
is displayed.
