RF Synthesizer Using EFC

This measurement example will help you measure the absolute phase noise of
an RF synthesizer using EFC.
To prevent damage to the test set's components, the input signal do not apply the
C A UTI ON
signal input connector until the input attenuator has been correctly set for the
desired configuration, as shown in Table 31. Apply the input signal when the
connection diagram appears

Required equipment

This measurement requires an Agilent 8257x with an EFC Input port, in
addition to the phase noise test system and your DUT. (For more information,
refer to the section
the coaxial cables and adapters necessary to connect the DUT and reference
source to the test set.
To ensure accurate measurements allow the DUT and measurement equipment to warm up
NO T E
at least 30 minutes before making the noise measurement
