Figure 5-1: Typical test setup for basic noise measurements

Measuring phase noise

1. Perform a [PRESET].

The application automatically starts a continuous measurement.
First, it searches for a carrier signal (see 

How to search for signals

). When

one has been found, it measures the noise characteristics of the DUT in the
default measurement (or frequency offset) range.
If no carrier could be found, a corresponding error message is displayed in the
status bar below the diagram.

2. You can stop the measurement (to analyze the measurement data in detail)

with the [RUN SGL] or [RUN CONT] key; [RUN SGL] performs one more
measurement, then stops, [RUN CONT] stops immediately.
