Stable RF Oscillator

Stable RF Oscillator
This measurement example will help you measure the phase noise of a stable
RF oscillator with frequency drift of <20 ppm over a period of thirty
minutes.
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 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.
