Trigger level
The vertical level the trigger signal must cross to generate a trigger
(on edge trigger mode).
Vertical bar cursors
The two vertical bars you position to measure the time parameter of a
waveform record. The oscilloscope displays the value of the active
(moveable) cursor with respect to the trigger and the time value
between the bars.
Waveform
The shape or form (visible representation) of a signal.
Waveform interval
The time interval between record points as displayed.
XY format
A display format that compares the voltage level of two waveform
records point by point. It is useful for studying phase relationships
between two waveforms.
YT format
The conventional oscilloscope display format. It shows the voltage of
a waveform record (on the vertical axis) as it varies over time (on the
horizontal axis).
