Spectrum:Averaging:Type Property
Short Name: Spectrum Averaging Type
Property of RFmxSpecAn
Specifies the averaging type for averaging multiple spectrum acquisitions. The averaged spectrum is used for spectrum measurement.
You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.
The default value is RMS.
| RMS (0) |
The power spectrum is linearly averaged. RMS averaging reduces signal fluctuations but not the noise floor. |
| Log (1) |
The power spectrum is averaged in a logarithmic scale. |
| Scalar (2) |
The square root of the power spectrum is averaged. |
| Max (3) |
The peak power in the spectrum at each frequency bin is retained from one acquisition to the next. |
| Min (4) |
The least power in the spectrum at each frequency bin is retained from one acquisition to the next. |
