Dual Trace A feature that allows the ScopeMeter test tool to display two separate live waveforms at the same time.

Duty Cycle Ratio of a waveform with respect to the total waveform period, as measured in percent.

Earth Ground Reference point that is directly connected to the ground via a conductor.

Envelope The display of a waveform that shows the variation extremes of several acquisitions (see also Min Max).

Events Triggering via red 4-mm banana jack input (EXT) is delayed by a number of events that occur on

INPUT A.

Falling Slope The part of a waveform that shows the voltage decreasing.

Filter Reduces or removes certain electrical components from a waveform (active input or memory). Is useful to suppress noise or to smooth a waveform.

Free Run Allows the ScopeMeter test tool to display a waveform without a trigger.

Freeze Holds a waveform acquisition: freezes the display for closer examination (see also Hold).

Frequency The number of times a waveform repeats in 1 second, measured in Hertz (Hz) where one Hz is one cycle per second.

Function keys The five blue keys along the top of the keypad. They change function based on the present mode or settings. Function key definitions appear in the Bottom Display.

Glitch A momentary spike in a waveform.

Glitch Detect Feature of ScopeMeter that increases its sampling rate to maximum so that glitches can be detected.

GND See "Ground level."

Ground level The voltage reference point in a circuit. It is indicated with "-" on the display.

Hard Copy A copy on paper of the display, made by a printer via the optical RS-232 interface.

Hertz (Hz) Unit of measure to count the number of times that an electrical cycle repeats every second. One Hertz is one cycle per second.

Hold Allows you to freeze the display for closer examination.
