BNC Coaxial-type input connector used for INPUT A and INPUT B.

Bottom Display The lower part of the display, where the function key menu is listed.

Capture 10 Divisions Records and displays 10 time divisions.

Capture 20 Divisions Records and displays 20 time divisions although the display shows only 10 at a time. Horizontal "Move" allows you to view the additional 10 divisions.

Continuous Auto Set Automatically selects the optimum settings for connected input signals and keeps track of any variation of the signal.

Contrast Contrast of the LCD. Can be adjusted as desired.

Cursors Movable display lines that allow you to make measurements between two locations on a waveform.

dB See "decibel."

DC See "Direct Current."

DC Coupling A mode of signal transmission that passes both AC and DC signal components to the INPUT A and INPUT B circuit (see also AC Coupling).

Decibel Measurements that indicate voltage or power comparison in a logaritmic scale.

Delta % Percentage change (delta) uses the present numerical reading as a relative reference. The display then shows a percentage that represents the difference between each new reading and the relative reference.

Delay Time The time between the trigger event and the real acquisition of the waveform.

Delta Time (dt) The change in time. The ScopeMeter test tool displays the amount of time displayed between the (vertical) cursors.

Digital Storage Capability Because of the design of digital oscilloscopes, signals are not displayed at the moment they are acquired. Instead, signals are first stored in memory, then sent to the display. This enables the ScopeMeter test tool to present several options when displaying information, including "negative delay."

Direct Current A signal with a constant voltage and current.

Display The Liquid Crystal Display area of the ScopeMeter test tool that is used to display all information, such as readings, waveforms, and text.

Division A part of a waveform, as defined alongside the lines of the grid on the display.
