Glossary
+
/– Rocker
The general-purpose rocker button on the front panel that you
can use to set parameters. The specific parameter assigned to the
+
/– rocker depends on other selections.
AC Coupling
A mode that blocks the DC component of a signal but passes the
dynamic (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 when you adjust the
+
/– rocker. The @
readout on the display shows the position of 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 oscilloscope digitizes at an effective 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.
