6.10 Setting the Pattern Trigger (ENHANCED)
Setting the Trigger Level
Selectable range: Eight divisions of the screen.
Resolution:
0.01 divisions: For example, the resolution for 2 mV/div is 0.02 mV.
Setting the 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 one division* of hysteresis around the trigger level.
*
The value above is an approximate value. It is not strictly warranted.
Setting the Trigger Coupling
You can select from the following.
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 the HF Rejection ON and OFF
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.
Setting the Hold Off
See section 6.4, “Setting the Hold Off Time.”
Notes on Setting the Pattern Trigger
• If you change the trigger type setting, the pattern trigger setting is disabled. However,
if the trigger type is set to pattern trigger again, the previous setting is activated.
• The operation is set to auto mode even when the trigger mode is set to auto level
mode.
You can set the trigger status to all trigger sources. On the channel selected to be the
clock channel, select the trigger slope.
• When activating a trigger in synchronization with the clock signal, if the setup time of
the pattern for the clock signal is 1 ns or more, keep the hold time at 1 ns or more.
