Terminology

The following list defines special terms used in this manual. The terms are listed in alphabetical order. Words shown in italics can be found elsewhere in the list.

AC See "Alternating Current."

AC Coupling A mode of signal transmission that passes the dynamic AC signal component to INPUT A and INPUT B but blocks the DC component. Useful to observe an AC signal that is normally riding on a DC signal.

Alternating Current An electrical signal in which current and voltage vary in a repeating pattern over time.

Amplitude The difference between the highest and lowest level of a waveform.

Attenuation The decrease in amplitude of a signal.

Average A processing technique to obtain the average value of a repetitive signal, useful to eliminate noise.

Auto Set Adjusts voltage scale and time base based on the characteristic of the active waveform, and automatically produces a stable waveform of usable size.

Backlight A light that brightens the display, useful for improving visibility in dark surroundings.

Bandwidth The range of frequencies that the ScopeMeter test tool can display accurately with no more than -3 dB (.7x) attenuation of the original signal.

Battery Save This feature enables the ScopeMeter test tool to shut itself down when running on batteries if the battery level is too low or if the test tool is not operated.
