Parameter Options, Installed Options & Auto Rules
The Phase Noise Optimization control lets you optimize the setup and behavior of
the Local Oscillator (LO) depending on your specific measurement conditions. You
may wish to trade off noise and speed, for example, to make a measurement faster
without regard to noise or with optimum noise characteristics without regard to
speed.

–
In instruments with EP0, balances close-in phase noise with spur
avoidance
–
In instruments without EP0 optimizes phase noise for small
frequency offsets from the carrier

–
In instruments with EP0, emphasizes close-in phase noise
performance without regard to spur avoidance
