Phase Noise Measurement Application

hase noise can be expressed as random, short-term frequency instability and is a key specification in both transmitter and receiver performance. For example, transmitting phase noise with digitally modulated signals leads to the spreading of symbols limiting the symbol rate. Phase noise in receiver local oscillators limits sensitivity by obscuring weak signals in LO phase noise sidebands. Keysight’s N9068EM0E phase noise measurement application for the UXA, PXA, MXA, EXA and CXA X-Series signal analyzers uses the direct spectrum method. This method measures single-sideband phase noise power in the signal analyzer. The application automatically configures and optimizes the analyzer’s settings, such as resolution bandwidth (RBW) and phase locked loops to achieve the highest measurement accuracy and speed.

Hardware Configuration

For optimizing measurements on phase noise signals with the phase noise measurement application, Keysight recommends a minimum level of X-Series multi-touch instrument hardware functionality at each instrument performance point. Supported instruments include:

Benchtop:

- UXA N9040B, N9041B, N9042B
- PXA N9030B, N9032B
- MXA N9020B, N9021B
- EXA N9010B
- CXA N9000B

PXIe:

- VSA up to 6 GHz M9391A
- VSA up to 50 GHz M9393A
