The Scope Marker Menu; Manual Time Markers Options - HP 1660CS-Series User Manual

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.
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.
