Setting the Level
10. Pressing the Level/Coupling soft key displays a menu used to set the level, coupling, hysteresis, and HF rejection.
The Level setting for each channel can be input directly using a USB keyboard. ( )
11. Turn the jog shuttle to move the cursor to the channel on which the level is to be set.
12. Press SELECT to display the level setting menu. 13. Turn the jog shuttle to set the level.
You can use the arrow keys to move between the digits. In addition, pressing
RESET sets the trigger level to 0 V. Setting the Hysteresis
14. Turn the jog shuttle to move the cursor to the channel on which hysteresis is to be set.
15. Press SELECT to select or .
Setting the Trigger Coupling
16. Turn the jog shuttle to move the cursor to the channel on which the coupling is to be set.
17. Press SELECT to select DC or AC.
Setting the HF Rejection
18. Turn the jog shuttle to move the cursor to the channel on which the HF rejection (HF Rej) is to be set.
19. Press SELECT to select ON or OFF.
Setting the Number of Times Condition B is to be Met
20. If the jog shuttle control is not set to Count, press the Count soft key.
21. Turn the jog shuttle to set the count.
You can use the arrow keys to move between the digits. Pressing RESET resets the value to 1.
Setting the Hold Off
22. Set the hold off time according to the procedures given in 6.4, “Setting the Hold Off Time.”
Note
• The status setting of conditions A and B applies to A -> B(N) trigger and A Delay B trigger. • The trigger level, hysteresis, trigger coupling, and HF rejection settings apply to simple trigger
and enhanced trigger.
Explanation
This function activates a trigger on the nth time condition B becomes true after condition A becomes true.
Setting Conditions A and B • Channel Status
Select the status of the channel from the following three choices. H: Above the specified trigger level
L: Below the specified trigger level X: Don’t care
• Condition
Select from the following two conditions.
Enter: Trigger is activated when all channels meet the specified status.
Exit: Trigger is activated when at least one channel no longer meets the specified status.
The Number of Times Pattern B is to be Met
1 to 108 times
Setting the Trigger Level
Range: 8 div within the screen Resolution: 0.01 div
For example, the resolution is 0.02 mV when the V/DIV setting is 2 mV/div.
Setting the Hysteresis
Sets a width to the trigger level so that the trigger is not activated on small changes. : Approximately 0.3 div* of hysteresis around the trigger level.
: Approximately 1 div* of hysteresis around the trigger level.
*: The values above are estimated values. They are not strictly guaranteed.
Setting the Trigger Coupling
Select from the following list of choices.
AC: Uses a signal that is obtained by removing the DC component from the trigger source signal as the trigger signal.
DC: Uses the trigger source signal as the trigger signal.
Turning ON/OFF the HF Rejection
Select ON when you wish to use a signal source obtained by removing the high- frequency components from the trigger signal as the trigger source.
Setting the Hold Off
See section 6.4, “Setting the Hold Off Time.”
Note
If you wish to use only one pattern condition to activate the trigger, use the pattern trigger. If the status for condition A and condition B are set to Xs (Don’t care), the trigger will not be activated.
