8.8.1 Level Trigger
Triggering occurs when the input signal crosses the preset
trigger level (voltage) with the preset trigger slope ( ,
).
When a trigger filter is used, triggering occurs only within
the filter width. This is useful to exclude noise.
Trigger Filter (MEM, REC)
Triggering occurs when the trigger conditions are met
within the filter width. This is useful to prevent spurious
triggering by noise.
The filter width is specified by the number of divisions of
the memory recorder function, while it is fixed to 10 ms,
which is enabled and disabled using the
buttons, for
the recorder function.
