Divide down (

)

is the integer to divide down measured frequency, only used in
large range two counters

is the sample clock rate, only used in sample clocked frequency
measurements

Here is how these variables apply to each method, summarized in Table 5-2.
•

One counter

—With one counter measurements, a known timebase is used for the source

frequency (

). The measurement time is the period of the frequency to be measured, or

•

Two counter high frequency

—With the two counter high frequency method, the

second counter provides a known measurement time. The gate frequency equals
1/

measurement time

•

Two counter large range

—The two counter larger range measurement is the same as a

one counter measurement, but now the user has an integer divide down of the signal. An
internal timebase is still used for the source frequency (

), but the divide down means that

the measurement time is the period of the divided down signal, or

where

is the divide

down.

•

Sample clocked

—For sample clocked frequency measurements, a known timebase is

counted for the source frequency (

). The measurement time is the period of the sample

clock (
