<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 an upper threshold the signal must exceed
(compared to the last measurement) before the reference level is adapted automati-
cally.
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:UPP 2
Example:
For an input signal level of currently 20 dBm, the reference level
is only adjusted when the signal level rises above 22
dBm.
Manual operation:
See
[SENSe:]ADJust:LEVel
Initiates a single (internal) measurement that evaluates and sets the ideal reference
level for the current input data and measurement settings. Thus, the settings of the RF
attenuation and the reference level are optimized for the signal level. The R&S
FSWP
is not overloaded and the dynamic range is not limited by an S/N ratio that is too small.
Example:
ADJ:LEV

Capturing data and performing sweeps
The only true measurement in MSRA mode in which I/Q data from the input signal is
captured and stored is performed by the MSRA primary application. This data acquisi-
tion is performed as in the I/Q Analyzer application, i.e. a specified frequency span of
the input signal is swept for a specified measurement time.
