Triggering the Instrument Using Analog Signals (Analog Trigger)
2. [In] trigger, [Out] trigger
When an input signal falls within (
[In]
) or gets out of a range (
[Out]
), which is determined by
specifying upper and lower values, an analog trigger is generated.
[In]
Upper limit value
Lower limit value
[Out]
Upper limit value
Lower limit value
Setting Description
Event With OR 1  to 4,000 Allows you to enter the number of events.
The instrument counts the number of times the window-trigger
condition is satisfied. Only after the count reaches the specified
number of events, an analog trigger is generated.
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 window-trigger condition continues to be satisfied
during the specified period, an analog trigger is generated.
Specifying this option prevents the instrument from being
unintentionally triggered due to noise.
Upper –f.s. to +f.s. Allows you to enter an upper limit value.
Lower –f.s. to +f.s. Allows you to enter a lower limit value.
Auto-
trigger
level *
Off  , On With the [On] setting, the instrument automatically specifies a
reference level and is triggered when an input signal exceeds
the range between the lower value, the sum of the reference
level and the lower limit value, and the higher value, the sum of
the reference level and the upper limit value. (p. 121)
In [Level of the last time] , the reference level used in the
previous measurement appears.
*: Available for the out trigger function only
The operation related to the in and out triggers varies depending on the trigger logical-conditions
(AND and OR).
With
OR In
The window-trigger condition is satisfied when an input signal
crosses the upper or lower limit value of the threshold (level)
and thereby falls within the range.
Out The window-trigger condition is satisfied when an input signal
crosses the upper or lower limit value of the threshold (level)
and thereby gets out of the range.
With AND In The window-trigger condition is satisfied when an input signal
is inside the range, which is specified by the upper and lower
limit values of the threshold (level).
Out The window-trigger condition is satisfied when an input signal
is outside the range, which is specified by the upper and lower
limit values of the threshold (level).
