Phase noise measurement using E5052B
Aug 19th, 2019, 9:32am
Hi All,

E5052B from Keysight uses "PLL method" to measure phase noise. I am measuring the phase noise of a 100 MHz square wave clock using this instrument. The effective offset range of the instrument is mentioned as 10 MHz for a 100 MHz clock, roughly 10% of the input clock frequency.

I am interested in phase noise beyond 10 MHz. What does the instrument measures at these offset frequencies? Does it show amplitude modulation(AM) sidebands along with phase modulation(PM) sidebands?
