Oscilloscope Bandwidth and Sample Rate
An oscilloscope’s bandwidth is typically described as the lowest frequency
at which input signal sine waves are attenuated by 3 dB (- 30% amplitude
error).
At the oscilloscope bandwidth, sampling theory says the required sample
rate is f
S
=2f
BW
. However, the theory assumes there are no frequency
components above f
MAX
(f
BW
in this case) and it requires a system with
an ideal brick- wall frequency response.
