7-72 Agilent Technologies E5500 Phase Noise Measurement System
Absolute Measurement Examples
RF Synthesizer using EFC
RF Synthesizer using EFC
This measurement example will help you measure the absolute phase noise
of an RF synthesizer using EFC.
CAUTION To prevent damage to the Agilent/HP 70420A test set’s hardware
components, the input signal must not be applied to the signal input
connector until the input attenuator has been correctly set for the desired
configuration, as show in Table7-15onpage7-80. Apply the input signal
when the Connection Diagram appears.
Required Equipment The following equipment is required for this example in addition the phase
noise test system and your unit-under-test (UUT).
NOTE To ensure accurate measurements, you should allow the UUT and
measurement equipment to warm up at least one hour before making the
noise measurement.
