Measured phase noise with an Agilent E5500 phase noise measurement system and plotted without spurs
1. External I/Q input level √ (I 2 + Q 2 ) = 250 mVrms, I/Q modulator attenuator set to auto.
2. Measured standard performance applies to units with serial numbers ending with 48050000 or greater. For units with lower
serial numbers, refer to the data sheet shipped with the unit or the version of this document dated November 6, 2007.
