Hi all,
I only have spetrum analyzer,can i measure Oscillator(900MHz) phase noise?And how to connect so that i can get the correct result?
Thanks in advance,
John
 

Yes, if the phase-noise of the analyzer is much better than the osc you trying to measure. To get phase noise reading. Read of dBc of your carrier at the required offset and add (10×log [RBW]) -RBW is the Resolution Bandwidth setting of your analyzer, 1kHz, 3kHz etc.
