Note on the measurement of SR D02 phase noise:
•
SR D02 features a phase noise floor which is better than the noise floor of current test setups as shown below with
e. g. the PN9000 setup of Aeroflex: noise floor measurement is limited around – 175 dBc/Hz by the noise floor of the
test setup,
•
Multi-channel measurement and cross correlation technique improve the noise floor of the test setup as e. g. with
the new DCNTS (Dual Core Noise Test System) of Aeroflex: residual noise floor is better than – 190 dBc/Hz
•
With this later setup, SR D02 noise floor is measured at – 182 dBc/Hz!
