5.3 Frequency Measurement Logic Level
The frequency of the rectangular signal can be measure-
ment when selecting the measurement function
.
The sampling rate (pulse-duty factor) of the rectangular
signal is measurement when switching by using the
key.
"
Turn measurement function selection dial to
.
"
Connect test leads to
and COM sockets and
connect to UUT.
"
The rectangular signal frequency is displayed.
"
To obtain the sampling rate value in percent, press
the key.
Pulse duration: ti
Quiescent period: tp
Period interval: T = ti + tp
Frequency: f = 1 / T
Sampling rate: g = ti / T
