Minor Division
Subdivisions of major divisions for more accurate measurement.
Minor divisions are seen as marks along the horizontal and
vertical center lines. The 222PS has five minor divisions in each
major division in both directions.
Normal Acquisition Mode
The most commonly used acquisition mode, in which the instru
ment displays one sample point for each point it acquires.
Normal Trigger Mode
A trigger mode in which the instrument does not acquire or
display a waveform until a trigger occurs. The trigger source,
level, and slope must be set appropriately.
Peak to Peak voltage (Vp p)
The voltage between the positive and negative peaks of a sine
wave.
Peak Voltage (Vp)
The voltage between the mean or average value and the peak of
the sine wave of an alternating voltage.
Probe
A device that allows you to transfer an electrical signal from an
external circuit into the oscilloscope.
Readout
Information, appearing on the screen, that is associated with a
signal trace. Readouts can be numeric values such as the volts
per division or symbols such as the kind of channel coupling.
Record Time Base Mode
The time base mode used for most time bases. When a trigger
occurs, a record of the waveform is acquired and displayed.
