AMPM:AM to AM Curve Fit:Type Property
Short Name: AMPM AM to AM Curve Fit Type
Property of RFmxSpecAn
Specifies the polynomial approximation cost-function of the device under test AM-to-AM characteristic.
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 Least Absolute Residual.
| Least Square (0) |
The measurement minimizes the energy of the polynomial approximation error. |
| Least Absolute Residual (1) |
The measurement minimizes the magnitude of the polynomial approximation error. |
| Bisquare (2) |
The measurement excludes the effect of data outliers while minimizing the energy of the polynomial approximation error. |
