Triggering the Instrument Using Analog Signals (Analog Trigger)
1. [Level] trigger
When an input signal crosses the specified level in the positive or negative direction, an analog
trigger is generated.
Level
Input waveform
Slope: [ ] [ ]
Setting Description
Level –f.s. to +f.s.
Default: 0 
Allows you to enter a level of the level trigger.
Slope With OR  The level-trigger condition is satisfied when a waveform crosses
the threshold value (level) in the positive direction.
The level-trigger condition is satisfied when a waveform crosses
the threshold value (level) in the negative direction.
With AND HIGH  The level-trigger condition is satisfied when a waveform is higher
than the threshold value (level).
LOW
The level-trigger condition is satisfied when a waveform is lower
than the threshold value (level).
Event With OR 1  to 4,000 Allows you to enter the number of events.
The instrument counts the number of times the level-trigger
condition is satisfied. An analog trigger is generated when the
count reaches the specified number of events.
With AND Not available
Filter Off  , 10 to 10,000 Allows you to enter a filter width in the number of samples. Only
after the level-trigger condition is continuously satisfied during
the specified period, an analog trigger is generated. Specifying
this option prevents the instrument from being unintentionally
triggered due to noise.
With the [Filter ] setting
Specifying the filter duration prevents the analog trigger from being unintentionally generated due
to noise, allowing it to be generated only after the level-trigger condition continues to be satisfied
during the specified duration (period) or longer.

Level at time
Noise does not generate any analog trigger.
