Glossary
AC Coupling
A mode that blocks the DC component of a signal but passes the dynam
ic (AC) component of the signal. Useful for observing an AC signal that is
normally riding on a DC signal.
Acquisition
The process of sampling signals from input channels, digitizing the
samples, processing the results into data points and assembling the data
points into a waveform record. The waveform record is stored in memory.
Active Cursor
The cursor that moves whenyou turnthe General Purpose Knob. The
@ readout onthe display shows the positionof the active cursor.
Aliasing
A false representation of a signal due to insufficient sampling of high
frequencies or fast transitions. A condition that occurs when an oscillo
scope digitizes at aneffective sampling rate that is too slow to reproduce
the input signal. The waveform displayed on the oscilloscope may have a
lower frequency than the actual input signal.
Area
Measurement of the waveform area taken over the entire waveform or the
gated region. Expressed in volt seconds. Area above ground is positive;
area below ground is negative.
Attenuation
The degree the amplitude of a signal is reduced when it passes through
an attenuating device such as a probe or attenuator, that is, the ratio of
the input measure to the output measure. For example, a 10X probe
attenuates, or reduces, the input voltage of a signal by a factor of 10.
Auto Trigger Mode
A trigger mode that causes the oscilloscope to automatically acquire if it
does not detect a triggerable event.
Autoset
A function of the oscilloscope that automatically produces a stable wave
form of usable size. Autoset sets up front panel controls based on the
characteristics of the active waveform. A successful autoset sets the volts
per division, time per division, and trigger level to produce a coherent
and stable waveform display.
Average Acquisition Mode
Inthis mode the oscilloscope acquires and displays a waveform that is
the averaged result of several acquisitions. This reduces the apparent
noise. The oscilloscope acquires data as in the sample mode and then
averages it according to a specified number of averages.
