Trig to X and Trig to O fields
The trigger point is always Time 0. Resolution for Trig to X and Trig to
O time values is 2% of the sweep speed(s/Div) setting. The default
value for these fields is 0 s, the trigger point.
When you select the Trig to X field and turn the knob, the Tx marker
will move across the display. As you move the marker, the time value in
the Trig to X field changes. A negative time value indicates the marker
is placed before the trigger point, and a positive time value indicates
the marker is placed after the trigger point. The Trig to O field works
similarly.
As you turn the knob when either the Trig to X or Trig to O field is
selected, the time value in the Tx t o To field also changes, showing the
time difference between the Tx and To markers. If the time displayed
in the Tx to To field is negative, the To marker is to the left of the Tx
marker.
When you select the Tx to To field and turn the knob, the Tx and To
markers will move in unison and maintain the preset Tx to To time
value.
You can also change the Tx to To, Trig to X, and Trig to O fields with
the pop-up keypad. Refer to the earlier paragraph entitled "Tx to To
Field" for a description and results of keypad entries in the Tx to To
field.
T Marker value display
Any time the markers (either voltage or time) are turned on, the
current marker settings may be displayed on the channel, trigger,
display and auto-measure menus by using the Display Options field
located to the right of the time base Delay field. The Display Options
field provides a pop-up menu that allows you to either select to set
channel labels or to view the Sample Period display or the Marker
Value display.
