Verify Frequency
Turns frequency verification on and off.
If frequency verification is on, the R&S FSW initiates the phase noise measurement
only if the frequency of the DUT is within a certain frequency tolerance range. The tol-
erance range is either a percentage range of the nominal frequency or a absolute devi-
ation from the nominal frequency.
If you define both an absolute and relative tolerance, the application uses the higher
tolerance level.
For more information see Chapter 4.6, "Frequency Determination" , on page 27.
