Introduction to Oscilloscopes and Probes
Performance Terms
Some terms and concepts related to how oscilloscopes
work are discussed below.
Bandwidth
Bandwidth is the sine wave frequency range of an
oscilloscope. By convention, bandwidth specifies the
frequency at which the amplitude of the displayed sine
wave reduces to 70.7% of the amplitude of the applied
sine wave signal.
Rise Time
Rise time is the time taken by a step or a pulse to rise
from 10% to 90% of its amplitude level.
Vertical Sensitivity
Vertical sensitivity is the range within which an amplifier
can amplify a weak signal. Vertical sensitivity is
expressed in volts per division (volts/div).
Sweep Speed
Sweep speed is the speed at which a waveform can
sweep across the screen of an analog oscilloscope. The
sweep speed of an oscilloscope is expressed in time per
division (sec/div).
