4.4 Trigger Functions
______________________________________________________________________________________________
4.4.1 Overview of the Trigger Functions
(1) Channel Trigger
Uses the input signals of CH1 and CH2
(Note)
.
(2) External Trigger
The input signal to the EXT TRIG connectors used as trigger source
(3) Timer Trigger
Triggering occurs from a preset start time to a preset stop time.
(Note)
CH2 is not available with the 8730-10.
(1) Setting Trigger Mode
Sets whether to accept a trigger repeatedly after measurement is
completed.
(2) Setting the Pre-trigger
Records the waveform before a trigger in addition to the waveform
after a trigger.
NOTE
When all trigger sources are OFF, the 8730-10, 8731-10 loads the waveform as
soon as it starts measurement (free-run operation).
During recording operation, "
Wait for trig
" appears on the screen until the trigger
sources are met.
4.4 Trigger Functions
The term "
Trigger
" refers to a signal which is used to control the timing
for recording start or stop.
The term "Triggering has occurred" refers to the state when such a signal
has activated recording start or stop.
The trigger mark
is displayed at the waveform trigger position (i.e.,
point where a trigger is activated).
A signal to activate a trigger is called the trigger source. The 8730-10,
8731-10 has three trigger sources as shown below.
The following two triggering methods are available:
