10.8 Analog Trigger
The analog signal input channels can be used as trigger source. The type of
trigger that can be used for the various functions is limited.
・
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
・
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, recorder&memory recorder function, or FFT function,
while it is fixed to 10 ms, which is enabled and disabled using the ON/OFF
keys, for the recorder function.
