The visual representation of an individual signal on a CRT.
Trigger
The signal used to initiate a sweep or acquisition on an oscilloscope.
Trigger level
The vertical level the trigger signal must cross to generate a trigger.
Trigger position
The position of the trigger reference point in the acquisition record.
Vector
A line created by the storage mode display system of the oscilloscope
that connects two data points.
Waveform
The shape or form (visible representation) of a signal.
X-Y
A display mode that compares the voltage levels of two signals. One
signal drives the horizontal or “X” axis and the other signal drives the
vertical or “Y” axis. It is useful for studying phase relationships between
two waveforms.
Z-Axis
The intensity aspect of an electron-beam (CRT) display. Z-Axis may also
refer to the circuitry that controls the CRT beam intensity.
