Phase Noise Measurement With PLL

Phase Noise Measurement With PLL
This procedure describes how to use the HP 70428A Microwave Source
Module as the reference source for phase noise measurements using a phase
lock loop. The μW LO output of the HP 70427A Microwave Downconverter
Module and the HP 70428A Microwave Source Module Option 002
(Tunable Source) can also be used as a microwave source.
The microwave source can output a signal between 2.4 GHz and 26.4 GHz in
600 MHz steps. The output power can be at least +16 dBm at frequencies
below 6.6 GHz and at least +10 dBm at frequencies up to 25.8 GHz.
Phase Noise Measurement with PLL Test One
This procedure can be used for all HP 3048A software versions. The
microwave source is not supported by any version of HP 3048A software;
therefore, it must be controlled manually.
