In addition to the graphical representation of the phase noise characteristics, the appli-
cation also provides several tables that show specific phase noise characteristics.
Measuring spurs
In addition to the graphical display of spurs in the diagram (spikes on the trace), the
application also features a result display that contains a list of all detected spurs.
►
Open the SmartGrid ( ) and drag the "Spurious List" item from the evaluation bar
into the display.
The spurious list contains all detected spurs (including their characteristics) on all
traces and all windows.

● "Spurious List" on page 90

Measuring spot noise
Spot noise is the phase noise or AM noise at a specific offset frequency (for example
the phase noise at 500 kHz).
►
Open the SmartGrid (
) and drag the "Spot Noise" item from the evaluation bar
into the display.
The table contains a list of spot noise values for selected frequency offsets (in the
default state, these are the decade edges) on each active trace.
More information:
● "Spot Noise" on page 91
Tip: You can define custom spot noise frequencies in the "Spot Noise" tab of the
"Noise Config" dialog box.
Measuring integrated noise
Integrated measurements show various noise characteristics, like the residual noise,
integrated over a certain offset frequency range.
►
Open the SmartGrid (
) and drag the "Integrated Measurements" item from the
evaluation bar into the display.
The table contains a list of integrated measurement results.
