Adjusting all Determinable Settings Automatically (Auto All)
Activates all automatic adjustment functions for the current measurement settings,
including:
●
Note:
MSRA operating modes. In MSRA operating mode, this function is only available
for the MSRA primary, not the secondary applications.
Remote command:
Adjusting the Center Frequency Automatically (Auto Frequency)
The R&S
FSWP 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.
Remote command:
Setting the Reference Level Automatically (Auto Level)
Automatically determines a reference level which ensures that no overload occurs at
the R&S
FSWP for the current input data. At the same time, the internal attenuators
are adjusted. As a result, the signal-to-noise ratio is optimized, while signal compres-
sion and clipping are minimized.
To determine the required reference level, a level measurement is performed on the
R&S
FSWP.
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)"
Remote command:
Resetting the Automatic Measurement Time (Meastime Auto)
Resets the measurement duration for automatic settings to the default value.
