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 1-2 for information on the flatness response. 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.

[a] Specified as 10% to 90% for rise time and 90% to 10% for fall time on a 0 dBm pulse.
[b] Specified as the overshoot relative to the settled pulse top power.
NOTE
For option 107 (10 m cable), add 5 ns to the rise time and fall time specifications.
