• CH5 to CH8 Pattern
You can set the pattern as follows:
H
The trigger source level is above the preset trigger level.
L
The trigger source level is below the preset trigger level.
X
Not used as a trigger source.
• Pattern Condition
Select the condition from the following.
True
Activates a trigger when the specified CH5 to CH8 pattern is met.
False
Activates a trigger when the specified CH5 to CH8 pattern is no longer met.
SPI -> Pattern
Activates a trigger when the trigger conditions of CH5 to CH8 are met after the trigger
conditions of the SPI Bus signal are met. The SPI trigger met condition is held until the
CH5 to CH8 trigger condition is met.
Condition not met
Trigger does not activate

• Slope of CH1 (SCK) Edge
Select the slope from the following:
Rising edge
Falling edge
• Enable State of CH4 (SS)
Select the state from the following:
H Status when the SS signal is above the trigger level. A trigger is activated when the SS
signal is high.
L Status when the SS signal is below the trigger level. A trigger is activated when the SS signal
is low.
