Synchronization of the reference frequencies
Synchronization of the reference oscillators both of the DUT and the R&S FSL strongly reduces the
measured frequency error.
1. Press the SETUP key.
2. Press the Reference Int/Ext softkey to switch to external reference.
The displayed frequency error should be <10 Hz.
