(2) External trigger signal input characteristics
Trigger breaks work according to the condition (leading edge/trailing edge) of signals input from
the external trigger cable. The external trigger signals of the trace points and the external trigger
signals of the break points use the same signals.
The input characteristics of the external trigger signals are shown in Table 5.5 below. See the table
before using external trigger signals.
