6.9.1.52 Phase Noise Optimization
Selects the LO (local oscillator) phase noise behavior for various desired operating
conditions.
For full details, see "Parameter Options & Installed Options" on page 2511 below.
Remote Command
:SYSTem:CALibration:ROW[1]|2|…|100:FREQuency:SYNThesis[:STATe] 1 | … | 5
For the meaning of each numeric option value, see "Parameter Options & Installed Options" on page
2511 below
:SYSTem:CALibration:ROW[1]|2|…|100:FREQuency:SYNThesis[:STATe]?
Example Select optimization for best wide offset phase noise:
:SYST:CAL:ROW1:FREQ:SYNT 2
Dependencies The SCPI command applies to the current selected Cal Group
If the subopcode does not reference an existing Cal row in the Cal Group, the error message “-221,
Settings conflict; Subopcode does not reference an existing Cal row” is generated
Couplings Coupled with "Phase Noise Optimization All Option" on page 2516
When Phase Noise Optimization All is ON, selects all available LO mappings, and Phase Noise
Optimization parameter will display All in the Configuration table. SCPI Query is still available to
determine which parameter will be displayed when Phase Noise Optimization All is OFF

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.
