[SENSe:]ADJust:CONFigure:LEVel:DURation:MODE
<Mode>
To determine the ideal reference level, the R&S
FSWP performs a measurement on
the current input data. This command selects the way the R&S
FSWP determines the
length of the measurement .
Parameters:
<Mode>
AUTO
The R&S
FSWP determines the measurement length automati-
cally according to the current input data.
MANual
The R&S
FSWP uses the measurement length defined by
[SENSe:]ADJust:CONFigure:LEVel:DURation
on page 100.

This command sets the center frequency to the frequency with the highest signal level
in the current frequency range.
Example:
ADJ:FREQ

<Threshold>
When the reference level is adjusted automatically using the
on page 102 command, the internal attenuators and the preamplifier are also
adjusted. To avoid frequent adaptation due to small changes in the input signal, you
can define a hysteresis. This setting defines a lower threshold the signal must fall
below (compared to the last measurement) before the reference level is adapted auto-
matically.
This setting can only be adjusted in the MSRA primary application, not in the secon-
dary applications.
Parameters:
<Threshold>
Range:
0 dB to 200 dB
*RST:
+1 dB
Default unit: dB
Example:
SENS:ADJ:CONF:HYST:LOW 2
For an input signal level of currently 20 dBm, the reference level
is only adjusted when the signal level falls below 18
dBm.
