Setup considerations for the free-running RF oscillator measurement
Measurement noise floor
The signal amplitude at the test set’s R input (Signal Input) port sets the
measurement noise floor level. Use Figure 100 on page 150 and Figure 101 on
page 150 to determine the amplitude required to provide a noise floor level
that is below the expected noise floor of your DUT. (The Checking the Beatnote
procedure in this section will provide you with an opportunity to estimate the
measurement noise floor that your DUT will provide.)
