Triggers
Note
• The status settings of conditions A and B apply to A->B(N) and A Delay B.
• The trigger level, hysteresis, trigger coupling, and HF rejection settings apply to both simple
and enhanced triggers.
Explanation
This setting is for activating a trigger the N
th
time condition B becomes true after
condition A has become true.
Conditions A and B
You can select the status of each channel.
H Above the preset trigger level
L Below the preset trigger level
X Don’t Care
You can select the condition.
Enter Trigger is activated when all channels match the specified condition.
Exit Trigger is activated when any of the channels no longer match the specified condition.
Number of Times Pattern B Is to Be Met
You can set the value in the range of 1 to 10
8
.
Trigger Level
The selectable range is 8 divisions within the screen. The resolution is 0.01 divisions.
For example, the resolution for 2 mV/div is 0.02 mV.
Hysteresis
Sets a width to the trigger level so that triggers are not activated by small changes in the
trigger signal.
Approximately 0.3 divisions
*
of hysteresis around the trigger level.
Approximately 1 division
*
of hysteresis around the trigger level.
* The value above is an approximate value. It is not strictly warranted.
Trigger Coupling
You can select the trigger coupling.
AC Uses a signal that is obtained by removing the DC component from the trigger source
signal.
DC Uses the trigger source signal as-is.
Turning ON/OFF the HF Rejection
Specify 15 kHz or 20 MHz if you wish to use a signal that is obtained by removing the
high frequency components (frequency components greater than 15 kHz or 20 MHz)
from the trigger source signal as the trigger source.
Hold Off
See section 6.4.
Note
If you wish to activate a trigger on a single pattern condition, use the pattern trigger (see
section 6.10). If you specify Xs for all of the status of condition A or condition B, triggers will
not be activated.
