Spectrum—Averaging Mode

[:SENSe]:SPECtrum:AVERage:TCONtrol EXPonential|REPeat

[:SENSe]:SPECtrum:AVERage:TCONtrol?

Select the type of termination control used for the averaging function.
This determines the averaging action after the specified number of
‘sweeps’ (average count) is reached.

Exponential - Each successive data acquisition after the average
count is reached, is exponentially weighted and combined with the
existing average.

Repeat - After reaching the average count, the averaging is reset and
a new average is started.

Factory Preset
and *RST:

Exponential

Remarks:

To use this command, the appropriate mode should be
selected with INSTrument:SELect.

Spectrum—Averaging Type

[:SENSe]:SPECtrum:AVERage:TYPE

LOG|MAXimum|MINimum|RMS|SCALar

[:SENSe]:SPECtrum:AVERage:TYPE?

Select the type of averaging.

Log

−

 The log of the power is averaged. (This is also known as video

averaging.)

Maximum

−

 The maximum values are retained.

Minimum

−

 The minimum values are retained.

RMS

−

 The power is averaged, providing the rms of the voltage.

Scalar

−

 The voltage is averaged.

Factory Preset
