Gets the frequency slope rate of a best-fit linear least square regression line measured over user specified sample analysis time interval as determined by Pulse Freq Phase Dev Range Length (%) method for each pulse. This value is expressed in Hz/us.This result is valid for linear FM and triangular FM modulation.

public int GetFMChirpRate(string selectorString, ref double[] value)

Remarks

This method gets the value of PulseResultsFMChirpRate attribute.

Parameters

NameTypeDescription
selectorStringstring

Specifies the result name.
Example: ""
"result::r1"
You can use the BuildResultString(string) method to build the selectorString.

valueref double[]

Upon return, contains the frequency slope rate of a best-fit linear least square regression line measured over user specified sample analysis time interval as determined by Pulse Freq Phase Dev Range Length (%) method for each pulse. This value is expressed in Hz/us.This result is valid for linear FM and triangular FM modulation.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
