Description:
This command determines the curve fit operation mode. AUTO ON (the default value) places the curve
fitter in automatic order selection. AUTO OFF gives a model with fixed numerator and denominator
order.
In automatic order selection (CALC:CFIT:ORDER:AUTO is ON), the curve fit operation starts with 1
pole and 1 zero. If the fit is poor, the orders increment and another curve fit operation is performed. This
iterative process continues until a model is found which more closely matches the measured frequency
response. The curve fit operation uses the number of poles and zeros specified with the
CALC:CFIT:ORD:POLES and CALC:CFIT:ORD:ZER commands as the upper bounds for this iterative
search.
If CALC:CFIT:ORDER:AUTO OFF is sent, the curve fit operation provides a model with the number of
poles and zeros specified with the CALC:CFIT:ORD:POLES and CALC:CFIT:ORD:ZER commands.
There is no iterative search for a better model.
Note
This command is not trace specific. It ignores the trace specifier.
