System Specifications and Characteristics

The video bandwidth in the meter can be set to High, Medium, Low and
Off. The video bandwidths stated in the table below are not the 3 dB
bandwidths, as the video bandwidths are corrected for optimal flatness
(except the Off filter). Refer to
flatness response of the High, Medium, Low and Off filters. The Off video
bandwidth setting provides the warranted rise time and fall time
specification and is the recommended setting for minimizing overshoot on
pulse signals.
