Parameter Options & Installed Options
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.
