Gets the start frequencies of the 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 the measured pulses. This value is expressed in Hz. This result is valid for linear FM and triangular FM modulation.

Syntax

Namespace: NationalInstruments.RFmx.PulseMX

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

Remarks

This method gets the value of PulseResultsFMChirpStartFrequency 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 start frequencies of the 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 the measured pulses. This value is expressed in Hz. 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.
