Figure 8-16 Trace bandwidth analysis result
NOTE
If the trace bandwidth analysis function is turned on, the straight line showing the cutoff
line is displayed parallel to the sweep parameter axis.
Step 5. When the cutoff point searched is not the target, press the
display the trace bandwidth analysis definition menu, and use the following functions:
Cutoff point re-search function
Inner search (two different cutoff points are
searched for with respect to the two currently
displayed cutoff points toward the inside on
the sweep parameter axis, and each parameter
of trace bandwidth analysis is displayed for the
cutoff point detected first)
Outer search (two different cutoff points are
searched for with respect to the two currently
displayed cutoff points toward the outside on
the sweep parameter axis, and each parameter
of trace bandwidth analysis is displayed for the
cutoff point detected first)
Press these softkeys several times if necessary to find the trace bandwidth analysis
parameter at the target cutoff point.
NOTE Cutoff point re-search does not cause the main marker to move, so it does not affect the
