Triggers
Explanation
Trigger Gate
Set the timing when the specified trigger condition is activated.
OFF
When the trigger condition is met, the waveform is acquired.
Active High
When the external signal is low, the waveform is not acquired even when the trigger condition
is met. When the trigger condition is met when the external signal is high, the waveform is
acquired.
Active Low
When the external signal is high, the waveform is not acquired even when the trigger
condition is met. When the trigger condition is met when the external signal is low, the
waveform is acquired.
* When trigger gate is set to Active, A->B(N) trigger and A delay B trigger cannot be selected.
Level
High or Low is determined by referring to the external trigger level. See section 6.6.
An external signal can be applied to the EXT TRIG IN/EXT CLOCK IN /TRIG GATE IN
terminal on the rear panel.
Trigger Input Terminal
The external trigger input terminal (EXT TRIG IN) is also used as an external clock input
terminal (EXT CLOCK IN). The terminal is used when you wish to activate the trigger
using an external signal.

Note
The determination level for the trigger gate input and the trigger level for the external trigger
input are common.
CAUTION
Applying a voltage that exceeds the maximum allowable input voltage indicated
above to the EXT CLOCK IN/EXT TRIG IN/TRIG GATE IN terminal can damage
the input section.
