Using the Oscilloscope
The Scope Marker Menu
The Scope Marker Menu
The oscilloscope has two sets of markers that allow you to make time
and voltage measurements. These measurements can be made either
manually (voltage and time markers) or automatically (time markers
only). The markers are accessed when you select the Markers choice
on the oscilloscope menu pop-up.
The default selection for both the time and voltage Markers fields is
Off.
Manual time markers options
Turn on the time markers by selecting the T Markers field and choosing
On from the pop-up menu. Three new fields appear to the right of the T
Markers field: Tx to To, Trig to X, and Trig to O. These fields allow you
to position the Tx (Time X) marker and the To (Time O) marker by
entering time values for these markers.
Tx to To field
The Tx to To field displays the time difference between the Tx marker
and the To marker. When you select the Tx to To field, turning the
knob moves both the Tx and To markers across the display without
changing the value in the Tx to To field. However, the values in the Trig
to X and Trig to O fields will change to reflect the movement of the Tx
and To markers.
You can change the value in the Tx to To field by changing the Trig to X
or Trig to O values, or by changing the Tx to To value using the keypad.
When you change the time value of Tx to To by using the keypad, the
difference between the new value and old value is split equally
bnetween Tx and To.
