The Frequency Settling Time measurement is used to measure the frequency settling time of
frequency-agile oscillators and subsystems. The Phase Settling Time measurement is used to measure
the phase settling time of phase-agile oscillators and subsystems. Automated measurements can reduce
user-to-user measurement variations, improving repeatability and measurement con
fi dence and saving
time in gathering results. To measure phase settling, a phase reference is required. This means that the
measurement tool must be frequency- referenced to the device under test, or must act as the frequency
reference to the device under test. To lock the reference to an external source, go to Setup > Con
fi gure
In/Out > Frequency Reference and choose External . Values from 1 MHz to 25 MHz in 1 MHz steps
can be used as an external reference.
To show a Settling Time display:
1. Click the Displays button or select Setup > Displays .
2. From the Folders box, select RF Measurements .
3. Double-click the Freq Settling icon or the Phase Settling icon in the Available displays box. This
adds the selected display to the Selected displays box (and removes it from the Available displays box).
4. Click the OK button.
