5.11 External Trigger

(1) External trigger signal input timing

The latch timing of the external trigger signal is shown in Figure 5.3.

Figure 5.3 Latch timing of external trigger signal

(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.
