RFmxEvdoMXSlotPhaseResultsFetchChipPhaseErrorLinearFitTrace Method
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.
Namespace: NationalInstruments.RFmx.EvdoMX
Assembly: NationalInstruments.RFmx.EvdoMX.Fx40 (in NationalInstruments.RFmx.EvdoMX.Fx40.dll) Version: 24.5.0.49283 (24.5.0.49283)
Syntax
public int FetchChipPhaseErrorLinearFitTrace( string selectorString, double timeout, ref AnalogWaveform<float> chipPhaseErrorLinearFit )
Public Function FetchChipPhaseErrorLinearFitTrace ( selectorString As String, timeout As Double, ByRef chipPhaseErrorLinearFit As AnalogWaveform(Of Single) ) As Integer
Parameters
- selectorString
- Type: SystemString
Pass an empty string. The signal name that is passed when creating the signal configuration is used. - timeout
- Type: SystemDouble
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. - chipPhaseErrorLinearFit
- Type: NationalInstrumentsAnalogWaveformSingle
Upon return, contains the data for a real waveform including the start, delta, and actual values.
Return Value
Type: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
