RF Measurements > Settling Time Displays Settling Time Displays
Elements of the Display
Item Display element Description
1 Top of graph Sets the frequency/phase that appears at the top of the graph. However,
note that the top of graph setting, vertical scale setting (Settings > Scale
tab), and Vertical Position settings interact. Adjusting this value changes the
frequency/phase at the top of the graph by adjusting the scale setting.
Phase Settling Time : Sets
2 Vertical Position Sets the frequency/phase value at the vertical center of the graph.
3 Autoscale Adjusts the Vertical and Horizontal scaling to display the entire trace on
screen.
4 Horizontal Position Sets the horizontal position of the trace on the graph.
5 Measurement readouts Displays measurement results. See Measurement Readout Text Color below.
6 Signal transition start indicator A blue vertical line that indicates the staring point of the Settling Time
measurement that is based on the signal transition away from the previous
settled state, if a previous settled state is found within the measurement
period.
7 Trigger point indicator An orange line and “T” (which appears below the graph) that indicates the
location of the trigger point in time.
8 +/- Tolerance indicators A pair of blue horizontal lines that show the tolerance range.
9 Settled time indicator A blue vertical bar that shows the point on the trace at which the measurement
has determined the signal frequency or phase to be settled.
10 Measurement length indicator A magenta vertical line that speci fi es the end of the allowed measurement
period. This is a control, not a result.
11 Scale Adjusts the horizontal (time) scale of the graph.
12 Clear Restarts multi-trace functions (Avg, Hold) and erases the trace.
13 Function Displays the Detection and Function selections for the selected trace.
(Detection is /-Peak for Settling Time measurements.)
14 Show Controls whether the selected Trace is visible or not. When trace is Off, the
box is not checked.
15 Trace
Selects a trace. Touching here displays a menu that shows the available
traces and whether they are enabled or not. If you select a trace that is not
currently enabled, it will be enabled.

Measurement Readout Text Color
The measurement readouts can appear in either black text or red text. Measurement results that appear
in black text indicate:
the signal is settled AND
the signal is settled longer than the minimum settled duration AND
the settling time is valid OR the settling time from trigger is valid
If any of the conditions listed are not met, the measurement results text is red.
