Burst width
A timing measurement of the duration of a burst.
Cursors
Paired markers that you can use to make measurements between two
waveform locations. The oscilloscope displays the values (expressed in
volts or time) of the position of the active cursor and the distance be
tween the twocursors.
Cycle Mean
An amplitude (voltage) measurement of the arithmetic mean over one
cycle.
Cycle RMS
The true Root Mean Square voltage over one cycle.
DC Coupling
A mode that passes both AC and DC signal components to the circuit.
Available for both the trigger system and the vertical system.
Digitizing
The process of converting a continuous analog signal such as a wave
form to a set of discrete numbers representing the amplitude of the signal
at specific points in time.
Edge Trigger
Triggering occurs when the oscilloscope detects the source passing
through a specified voltage level in a specified direction (the trigger
slope).
Envelope Acquisition Mode
A mode in which the oscilloscope acquires and displays a waveform that
shows the variation extremes of several acquisitions.
Gated Measurements
A feature that lets you limit automated measurements to a specified
portion of the waveform. You define the area of interest using the vertical
cursors.
GPIB (General Purpose Interface Bus)
An interconnection bus and protocol that allows you to connect multiple
instruments in a network under the control of a controller. Also known as
IEEE 488 bus. It transfers data with eight parallel data lines, five control
lines, and three handshake lines.
Ground (GND) Coupling
Coupling option that disconnects the input signal from the vertical sys
tem.
Hard Copy
An electronic copy of the display in a format useable by a printer or
plotter.
