Frequency
Timing measurement. The reciprocal of the period. Meas-
ured in Hertz (Hz) where 1 Hz = 1 cycle per second.
GPIB (General Purpose Interface Bus)
An interconnection bus and protocol that allows you to
connect multiple instruments in a network under the con-
trol of a controller. Also known as IEEE 488 bus. Transfers
data with eight parallel data lines, five control lines, and
three handshake lines.
Graticule
A grid on the display screen that serves as horizontal and
vertical scales. You can use it to visually measure waveform
parameters.
Ground (GND) coupling
Coupling option that disconnects the input signal from the
vertical system.
Hardcopy
A copy, in a format useable by a printer or plotter, of the
display.
Holdoff, trigger
The time after a trigger signal that must elapse before the
trigger circuit will accept another trigger signal.
Horizontal Axis
Usually, the axis along which an oscilloscope measures the
timing of a signal. The exception to this is XY mode. (See
definition below.) The timing of a signal is usually meas-
ured in seconds-per-division, or fractions of a second-per-
period.
Inverted Waveform
A waveform that is flopped along its horizontal axis, so that
it appears upside-down.
Intensity
Displays brightness.
