Analog Oscilloscopes
Bandwidth:
Bandwidth is one of the most important
oscilloscope specifications as it represents
the range in which an oscilloscope can
display frequency accurately. It is defined
by the frequency response curve when the
attenuation is at the -3 dB mark. As a general
rule of thumb, the oscilloscope's bandwidth
should be at least five times the highest
frequency of the signal under test.
Delayed Time Base:
A feature in some analog oscilloscopes that
allows a single signal to be viewed at two
different time bases with the second time
base expanding a portion of the waveform
and starting at some point after the main time
base begins. This allows you to see events
that are not visible with the main time base
sweep.
Sampling Rate:
Specifies the rate at which a waveform or
signal is sampled. Sampling is the process of
converting a portion of the input signal into
a number of discrete electrical values for
the purpose of storage, display or further
processing. The unit of measure is samples
per second (Sa/s).
Sweep Rate:
Rate at which a sweep generator repeats a
sweep cycle.
