Behavior. Bandwidth refers to the range of frequencies the instrument can acquire and display accurately with less than 3 dB
attenuation. Each input channel has its own bandwidth selection.
To take accurate measurements, the input frequency should be much less than the rated bandwidth of the instrument. A good
rule to follow is to ensure the bandwidth of the instrument system is three to five times the bandwidth of the signal that you want
to measure.
