Internal Clock (Asynchronous Clock)
Click on Internal Clock, and then select the Frequency from the pull down
menu to set up the frequency of the device under test (DUT). The frequency
of the Internal Clock must be at least four times higher then the frequency
of the Oscillator on the DUT. Or, select the frequency
from
the pull down menu on Tool Bar as Fig 3-2 shows.
Tip:
Connect the signal output pin of the tested board to the Signal connector of
Logic Analyzer to measure it using the internal clock of Logic Analyzer.

Click on External Clock, and then select “Rising Edge” or “Falling Edge” as the
trigger condition of the DUT. In the Frequency column, type the frequency of
the oscillator on the DUT.
Tip:
The External Clock is applied when the frequency of the oscillator on the
tested board is less then 100MHz. Connect the output pin of oscillator on the
tested board to the CLK pin of Logic Analyzer as shown in Fig 3-3.
