Chapter 2 Operating Your Frequency Counter

Note that this value represents the last measurement of the input signal rounded to
eleven digits. The Counter uses it as the reference offset value, and reverses the sign
from + to − .

−12* µ (120 µs) is displayed, for example, at the completion of the next measurement.
This value (−0.00012) is the small difference between the signal being measured and
the reference value (OFFS: −10.00000 M) obtained in step 5.
Using the reference allows you to observe small differences in the
13th–15th digits which would not be observable in the 12-digit display.
Overview of Statistics (Stats) Menu
The Stats menu allows you to:
• select which computed statistics you want displayed
(SHOW: STD DEV, MEAN, MAX, or MIN).
• choose between having the actual measurement or statistical result displayed
(SHOW: MEAS).
• select the number of measurements you want to make for each computed statistic
(N:).
• enable or disable the Stats mode (STATS: ON or OFF).
• enable the Counter to perform statistical computation on only measurements that
are within the user-entered limits; that is, filter data (USE: IN LIMIT), or
• enable the Counter to perform statistical computation on all measurements,
whether they fall in or out of the user-entered limits (USE: ALL MEAS).
• configure Stop/Single key to initiate a set of N measurements (ON SINGLE: 1
or N).
