Auto )" on page 67

Manual )" on page 67
[SENSe:]ADJust:CONFigure:HYSTeresis:LOWer <Threshold>
When the reference level is adjusted automatically using the [SENSe:]ADJust:
LEVel on page 139 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 a lower threshold the signal must fall
below (compared to the last measurement) before the reference level is adapted auto-
matically.
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 68
[SENSe:]ADJust:CONFigure:HYSTeresis:UPPer <Threshold>
When the reference level is adjusted automatically using the [SENSe:]ADJust:
LEVel on page 139 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 67
[SENSe:]ADJust:CONFigure:TRIGger <State>
Defines the behavior of the measurement when adjusting a setting automatically (using
SENS:ADJ:LEV ON, for example).
