Meas Setup
PhNoise Opt
Selects the LO (local oscillator) phase noise behavior for various desired operating conditions.
Auto
Selects the LO (local oscillator) phase noise behavior to optimize dynamic range and speed for various
test set operating conditions.
The X-Series has two grades of LO; a high performance LO that gives the best phase noise performance;
and a medium-performance LO that gives excellent performance.
Remote Command: [:SENSe]:FREQuency:SYNThesis[:STATe] 1|2|3
[:SENSe]:FREQuency:SYNThesis[:STATe]?
Example: FREQ:SYNT 2 selects optimization for best wide offset phase noise
Notes: Parameter:
1 - optimizes phase noise for small frequency offsets from the carrier.
2 - optimizes phase noise for wide frequency offsets from the carrier.
3 - optimizes LO for tuning speed
Preset: Because this function is in Auto after preset, and because Span after preset >
314.16 kHz (see Auto rules, next section) the state of this function after Preset
is 2.
Dependencies: Does not appear in all models. The key is blank in those models, but the
SCPI command is accepted for compatibility (although no action is taken).
