Triggering
Specifies trigger count or trigger period (interval time setting), and
generates valid trigger signal and acquires waveform only a specific
condition is satisfied.
Selects Count, Burst, Extra or Missing as event type.
Generates valid trigger signal every specified count of trigger signal. It
is suitable for operation check of counter circuit.
Count setting: 1 to 9999 (selecting Coarse allows setting every 100
steps)
Generates valid trigger signal when trigger signal period exceeds the
interval time. It is suitable for observation of burst waveforms, etc.
Interval time: 0.15
µ
s to 1 s (can also be set roughly by Coarse)
Generates valid trigger signal when trigger signal period is smaller than
the interval time.
Acquires waveform when the trigger period is shortened by glitch in a
clock signal or spike noise in the power line. It is suitable for observation
of glitches.
Interval time: 0.20
µ
s to 1 s (can also be set roughly by Coarse)
