RF Measurements > Spurious Spurious Display
Item Display element Description
1
dB/ div Sets the vertical scale value. The maximum value is 20.00 dB/division.
2 Vert Position
Sets the top of graph value. This is only a visual control for panning the graph.
The Reference Level is adjusted in the Toolbar and the Ampl control panel.
By default, Vert Position = Ref Level.
3 Check Mark Indicator Indicates the display for which the acquisition hardware is optimized.
4 Pass / Fail readout Indicates whether one or more spurs have exceeded a limit speci fi ed on
the Settings > Limits tab.
5 Ref: If enabled, displays the power reference level.
6 Trace function Indicates the trace processing method. If Average or Max Hold is selected,
this readout displays the number of traces being processed (averaged or
compared for the Max Hold value).
7
Clear Restarts multi-trace functions (Average, Max Hold).
8 Stop Adjusts the graph stop frequency. This setting affects only visual scaling, not
measurement parameters.
9 Green bar Indicates the range that is selected on the Settings > Ranges and Settings >
Limits tabs.
10 Spur table Displays spur measurements. See the following table for details.
11 Start Adjusts the graph start frequency. This setting affects only visual scaling, not
measurement parameters.
12 Autoscale Adjusts the Vertical and Horizontal scaling to display the entire trace on
screen. Selects Multi-range display mode.
13 Bottom-of-graph readout Indicates the amplitude at the bottom of the graph. This value changes with
the dB/div and Vertical Position settings.
