Hi Ashish,
1. Use the SA(spectrum Analyzer) and capture the plots using the phase
noise utility in SA (if Your SA has this option) , this can be done manual
or you can automate for different channels to capture the screen of SA.
2. Capture the sample points of SA (e.g : 401 points for E4404B) and plot
them , calculate the dBc at required offset. This also can be automated for
different channels.
Not sure if Multi channel equipments are available to capture the Phase
noise, try to route the single channel towards equipment using combiner and
one at time. I am sure this can also be controlled/automated.

Not knowing your specific application I have to ask - Phase noise or jitter?
Jitter and phase noise are essentially Time and Frequency domain
representations of the same thing. Most jitter measuring equipment, mostly
oscilloscopes, can convert to phase noise, or you can calculate it from the
data.

Hi,
We have requirements of measuring Phase Noise of multi port PLLs (100 Pcs in
a weeks time).
Do any of you have suggestion on measurement technique ?
Although we have one Phase Noise measurement equipment but it has only one
channel.
I am looking for multi channel equipment or any other out of box suggestion
to quickly measure Phase noise
Regards
Ashish
