Example Procedure for Changing the Number of Digits of Resolution
Displayed for More Precise Measurements
1Turn POWER key OFF then ON again (cycle POWER key) to preset the Counter.
2 Connect (for demonstration purposes) the 10 MHz Out signal to the channel 1
input.
3 Press Other Meas key until PERIOD 1 is displayed.
After a few seconds, 0.100,000,000,0 µs is displayed. Hence, the default number of
digits (or resolution) displays a precise measurement.
4 To demonstrate how to use “digits arming” to change the number of digits
displayed, perform the following steps first.
a. Press Gate & ExtArm key
GATE: TIME is displayed.
b. Press any one of the arrow keys until AUTO is displayed.
c. Press Enter or Run key.
0.100,0 µs is displayed. Note that fewer digits are displayed.
In “auto arming” you produce results quickly. The short gate time produces a
lower-resolution result.
