Adjusting all Determinable Settings Automatically ( Auto All )
Activates all automatic adjustment functions for the current measurement settings.
This includes:
●
Auto Frequency
●
Auto Level
Note: Auto measurement. For some measurements, the Adjusting all Determinable
Settings Automatically ( Auto All ) function determines the required measurement
parameters automatically. In this case, the progress of the auto measurement is indica-
ted in a message box.
See Chapter 7.1, "Auto Measurements", on page 121.

Adjusting the Center Frequency Automatically ( Auto Frequency )
The R&S FSV/A adjusts the center frequency automatically.
The optimum center frequency is the frequency with the highest S/N ratio in the fre-
quency span. As this function uses the signal counter, it is intended for use with sinus-
oidal signals.
At the same time, the optimal reference level is also set (see " Setting the Reference
Level Automatically ( Auto Level )" on page 371).
Remote command:
[SENSe:]ADJust:FREQuency on page 921
Setting the Reference Level Automatically ( Auto Level )
Automatically determines a reference level which ensures that no overload occurs at
the R&S FSV/A for the current input data. At the same time, the internal attenuators
are adjusted so the signal-to-noise ratio is optimized, while signal compression and
clipping are minimized.
To determine the required reference level, a level measurement is performed on the
R&S FSV/A.
If necessary, you can optimize the reference level further. Decrease the attenuation
level manually to the lowest possible value before an overload occurs, then decrease
the reference level in the same way.
You can change the measurement time for the level measurement if necessary (see "
Changing the Automatic Measurement Time ( Meastime Manual )" on page 411).
Remote command:
[SENSe:]ADJust:LEVel on page 921
Resetting the Automatic Measurement Time ( Meastime Auto )
Resets the measurement duration for automatic settings to the default value.
