Using the Oscilloscope
The Scope Marker Menu
Set on field
The Set on field assigns an input waveform to the Tx or To marker, or
allows the marker to be set manually (with the MANUAL selection in
the pop-up). When you select the Set on field, a pop-up appears
showing the waveform sources available.
The default selection for the Set on field is the lowest letter and
number combination.
Type field
The Type field selects the units in which an automatic time marker
level will be specified. The automatic time marker can have a level
expressed as either a percentage of the waveform top-base voltage
(Percent) or as an absolute voltage level (Absolute). The default
selection is Percent.
at Level field
When the marker type is Percent, the at Level field sets the Tx or To
marker to a percentage level (from 10% to 90%) of the top-base
voltage on the waveform selected by the Set on field. When you select
the at Level field, you can change the percentage by turning the knob
or by entering a value using the keypad. You can enter any percentage
from 10% to 90% in increments of 1%.
When the marker type is Absolute, the at Level field sets the Tx or To
marker to the specific voltage level. The allowable voltage range that
can be selected is the vertical range for the selected channel (that is,
offset Ê 2 times v/div)). You can enter any voltage from -12 V to 4 V in
increments of 30 mV.
The default value for the at Level field is 50%.
The power-up default value for the at Level field is the selected
channel offset value. If the vertical range parameters (for example:v/
div, offset, probe factor) of a channel are changed such that the current
at Level voltage is no longer valid, the at Level voltage will track the
limit of the vertical range.
