Agilent / HP / Keysight 85671A
85671A Phase Noise Measurements Utility
Description
This unit is a downloadable program that transforms your Agilent 8560 series spectrum analyzer into a phase noise tester.
This removes the work in performing phase noise measurements.
This utility eliminates the time-consuming task of hand-drawing phase noise plots.
To measure oscillator phase noise, you no longer need to spend time manually tuning your spectrum analyzer to multiple frequency offsets.
It can quickly and easily generate graphs of phase noise (dBc/Hz) versus log offset frequency or integrate the results over a band of interest for degrees or radians RMS.
Key Points
Direct phase noise readout from log frequency graph
Variable filtering
Calculation of integrated RMS noise
Spot frequency measurements
Digitized hardcopy and storage
