Fetches the chip phase error trace linear fit trace for the SlotPhase measurement. The linear fit is obtained from the chip phase error on a half-slot basis. If a transient duration greater than zero is configured, the linear fit computation ignores the data of the transient duration on either side of the half-slot boundary and extrapolates the phase error to the half-slot boundaries.

public int FetchChipPhaseErrorLinearFitTrace(string selectorString, double timeout, ref AnalogWaveform< float > chipPhaseErrorLinearFit)

Parameters

NameTypeDescription
selectorStringstring

Pass an empty string. The signal name that is passed when creating the signal configuration is used.

timeoutdouble

Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete.

chipPhaseErrorLinearFitref AnalogWaveform< float >

Upon return, contains the data for a real waveform including the start, delta, and actual values.

Returns

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