MKRVAL + fixed value
Fixed Value
Fixed value specified by numerical value
1
MKRVAL: Indicates the measurement parameter value (measurement) at the position of the main marker
(marker 0).
Fixed value: Indicates the absolute value of the measurement parameter if there is no
∆
marker; it is a
relative value with reference to the tracking
∆
marker tracking (∆
marker that moves with the main marker)
is present and a relative value with reference to the fixed
∆
marker if the fixed marker is present.
5. Press the BW Fixed Value, and input the desired bandwidth value.
Implement Trace Bandwidth Analysis
The following describes the steps to implement trace bandwidth analysis:
1. Activate the trace used to implement trace bandwidth analysis.
2. Display the main marker and move it to the desired position on the
trace to analyze trace bandwidth. To move the main marker to the
peak of the trace, see Search the maximum/minimum peak.
3. Press the Marker Search key to display the Marker Search menu.
4. Press Bandwidth > ON|OFF to turn On or Off the trace bandwidth
analysis function.
Once the trace bandwidth analysis function is turned
On, the bandwidth (width), center value (center), Q (Q), peak
(peak), ∆L(∆L), and ∆R(∆R) are displayed in the Marker
Statistics/Trace Bandwidth Analysis Result area on the top-left
of the screen.
If the trace bandwidth analysis function is turned On,
the straight line showing the cutoff line is displayed parallel to
the sweep parameter axis.
Cutoff point re-search does not cause the main marker to move, so it does
not affect the peak value. If the two cutoff points cannot be found by trace
bandwidth analysis, the message Target Value Not Found will appear at the
bottom left side of the bar of the screen. If a partial search range is
specified by following Searching for Positions that Match Specified Criteria,
trace bandwidth analysis will be executed within that range. Even if the
trace bandwidth analysis function is turned Off, the marker used for
analysis will not disappear from the screen.
