[SENSe:]ADJust:CONFigure:DURation:MODE <Mode>

In order to determine the ideal reference level, the R&S FPL1000 performs a measure-

ment on the current input data. This command selects the way the R&S FPL1000

determines the length of the measurement .

Parameters:

<Mode> AUTO

The R&S FPL1000 determines the measurement length auto-

matically according to the current input data.

MANual

The R&S FPL1000 uses the measurement length defined by

[SENSe:]ADJust:CONFigure:DURation on page 764.

*RST: AUTO

Manual operation: See "Resetting the Automatic Measurement Time (Meastime

Auto)" on page 344

See "Changing the Automatic Measurement Time (Meastime

Manual)" on page 345

[SENSe:]ADJust:CONFigure:HYSTeresis:LOWer <Threshold>

When the reference level is adjusted automatically using the [SENSe:]ADJust:

LEVel on page 766 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 345

[SENSe:]ADJust:CONFigure:HYSTeresis:UPPer <Threshold>

When the reference level is adjusted automatically using the [SENSe:]ADJust:

LEVel on page 766 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.
