FSW-K7
269User Manual 1173.9240.02 ─ 17
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
will only be adjusted when the signal level falls below 18 dBm.
Manual operation: See "Lower Level Hysteresis" on page 127
[SENSe:]ADJust:CONFigure:HYSTeresis:UPPer <Threshold>
When the reference level is adjusted automatically using the [SENSe:]ADJust:
LEVel on page 269 command, the internal attenuators and the preamplifier are also
adjusted. In order 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
automatically.
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
will only be adjusted when the signal level rises above 22 dBm.
Manual operation: See "Upper Level Hysteresis" on page 127
[SENSe:]ADJust:LEVel
This command initiates a single (internal) measurement that evaluates and sets the
ideal reference level for the current input data and measurement settings. This ensures
that the settings of the RF attenuation and the reference level are optimally adjusted to
the signal level without overloading the R&S FSW or limiting the dynamic range by an
S/N ratio that is too small.
Example:
ADJ:LEV
Usage: Event
Manual operation: See "Setting the Reference Level Automatically (Auto Level)"
on page 87
[SENSe:]ADJust:SCALe:Y:AUTO[:CONTinuous] <State>
Activates automatic scaling of the y-axis in all diagrams according to the current mea-
surement results. Currently auto-scaling is only available for AF measurements. RF
power and RF spectrum measurements are not affected by the auto-scaling.
