Testing the Agilent/HP 8644B Internal/External
10 MHz
This measurement example will help you measure the absolute phase noise
of an RF synthesizer.
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
when the Connection Diagram appears.
The following equipment is required for this example in addition to the
phase noise test system and your unit-under-test (UUT).
To ensure accurate measurements, you should allow the UUT and
measurement equipment to warm up at least one hour before making the
noise measurement.
