To Change Trigger Point Indicator
Time reference is the reference point on the display for delay time. To
move the trigger point indicator from the time reference, do the following:
1 Enter the Scope menu by pressing the button.
2 In Scope menu, press F3 to access Delay submenu.
3 On page 1/2, press F2 softkey to display a pull- up menu for the
following selections:
• Left (10% of the horizontal full scale)
• Center (50% of the horizontal full scale)
• Right (90% of the horizontal full scale)
All events displayed at the left of the trigger point are called pre- trigger
information because they happen before the triggering. All events at the
right of the trigger point, measuring after the trigger point, are called
post- trigger information. The amount of delay range (pre- trigger and
post- trigger information) is available depending on the sweep speed
selected and memory depth.
Notice that the sweep speed is set to 1 division step sequence with indicator at the
right corner in the waveform display area (refer to “Oscilloscope Display Overview 23”).
Turn the vernier scale on by pressing the rotary switch once. You will notice the
indicator is disappeared and now you can move the sweep speed in smaller increments.
