PhNoise Opt State

Selects the LO (local oscillator) phase noise behavior for various operating conditions.

IF Gain

Sets the IF Gain function to Auto, Low Gain or High Gain. These settings affect sensitivity and IF

overloads.

IF Gain Auto

Activates the auto rules for IF Gain. When Auto is active, the IF Gain is set to High Gain under any of

Preset: OFF
State Saved: Saved in instrument state.
Range: Auto|Man
Readback Text: “Auto” is underlined when Auto is selected, otherwise Man is underlined.
Initial S/W Revision: A.04.20
Key Path: Meas Setup
Remote Command: [:SENSe]:CHPower:FREQuency:SYNThesis[:STATe] 1|2|3
[:SENSe]:CHPower:FREQuency:SYNThesis[:STATe]?
Example: CHP:FREQ:SYNT 1
CHP:FREQ:SYNT?
Notes: Parameter key:
1. optimizes phase noise for close-in from the carrier.
2. optimizes phase noise for wide-offset from the carrier.
3. optimizes LO for tuning speed.
Preset: 3
State Saved: Saved in instrument state.
Range: Hardware Dependent:
PXA: Best Close-in Noise [offset < 140 kHz] | Best Wide-offset Noise [offset
> 160 kHz] | Fast Tuning
MXA, EXA: Best Close-in Noise [offset < 20 kHz] | Best Wide-offset Noise
[offset > 30 kHz] | Fast Tuning
