Sampling oscilloscopes are digital oscilloscopes that sample their input signals prior to any amplification or attenuation. The architecture of a sampling oscilloscope reverses the position of the attenuator/amplifier and the sampling bridge. The input signal is sampled before any attenuation or amplification is performed. A low bandwidth amplifier can then be utilized after the sampling bridge because the signal has already been converted to a lower frequency by the sampling gate. This results in a much higher bandwidth instrument. (www.tek.com)
