E5500 Phase Noise Measurement System Version A.02.00
In the Agilent E5500 Phase Noise Measurement System, residual
phase noise measurements are made by selecting Residual Phase
Noise (without using a phase locked loop).
There are five calibration methods available for use when making
residual phase noise measurements. They are:
G
User Entry of Phase Detector Constant
G
Measured ±DC Peak
G
Beatnote
Φ
G
Double-Sided
M Spur
G
Single-Sided Spur
The method used will mainly be determined by the sources and
equipment available to you.
When calibrating the system for measurements, remember that the
calibration is only as accurate as the data input to the system
software. See
