E5500 Phase Noise Measurement System Version A.02.00
This measurement example will help you measure the absolute phase
noise of an RF synthesizer.
CAUTION:
To prevent damage to the Agilent 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
Table
5-7. Apply the input signal when the connection diagram appears.
Table 5-5
shows equipment required for this example in addition to
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.
