19.2 Trigger Section
Item
Specifications
Edge on A:
Trigger occurs on the OR condition of the edge while condition A is true.
Condition A:
True/False
OR:
Trigger occurs on the OR of trigger conditions that are specified on multiple
trigger sources. The OR condition can also be specified on each logic bit.
B > Time:
Trigger occurs when time of satisfaction of (pulse width trigger) condition B (time
during which the condition is satisfied) is greater than or equal to a specified time.
Specified time:
100 ns to 10 s (resolution is 100 ns)
B < Time:
Trigger occurs when time of satisfaction of (pulse width trigger) condition B is less
than or equal to a specified time.
Specified time:
100 ns to 10 s (resolution is 100 ns)
B Time Out:
Trigger occurs when the satisfaction of (timeout trigger) condition B reaches a
specified time.
Specified time:
100 ns to 10 s (resolution is 100 ns)
Period:
Periodic trigger. The following four types are available.
T > Time:
Trigger occurs when the period of condition T is greater than or equal to a
specified time.
Specified time:
100 ns to 10 s (resolution is 100 ns)
T < Time:
Trigger occurs when the period of condition T is less than or equal to a specified
time.
Specified time:
100 ns to 10 s (resolution is 100 ns)
T < T1 < T2:
Trigger occurs when the period of condition T is within a specified time range.
Specified time:
Time1:
100 ns to 10 s
Time2:
200 ns to 10 s (resolution is 100 ns)
T < T1, T2 < T: Trigger occurs when the period of condition T is outside a specified time range.
Specified time:
Time1:
100 ns to 10 s
Time2:
200 ns to 10 s (resolution is 100 ns)
Window:
Trigger occurs when the trigger source enters or exits the range specified by two
points. Window OR of multiple channels is possible. Logic bits can also be
included in the edge OR condition.
Wave Window:
Trigger for monitoring the power supply. A realtime template is created by setting
a tolerance (window width) to a waveform derived by averaging 1 to 4 cycles of
waveforms before the current waveform. The current waveform is compared
against the realtime template. If the current waveform falls outside the realtime
template, a trigger is activated.
• Conditions A and B are parallel pattern conditions that are set separately to High, Low, or “Don’t
Care” for each channel (CH1 to CH16), Logic A, and Logic B.
• OR conditions can be set to
,
, or “Don’t Care” for CH1 to CH16, Logic A, and Logic B.
• Hold off time cannot be specified for period triggers.
