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 Figure 11- 159 for information on the
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.
Rise Time, Fall Time, and Overshoot versus Video Bandwidth
Settings
9
Specified as 10 % to 90 % for rise time and 90 % to 10 % for fall time on a 0 dBm pulse.
10
Specified as the overshoot relative to the settled pulse top power.
