RFmxLTE_PVTCfgAveraging

int32 __stdcall RFmxLTE_PVTCfgAveraging (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 averagingEnabled, int32 averagingCount, int32 averagingType);

Purpose

Configures averaging for the power versus time (PVT) measurement.

Parameters

Input
Name	Type	Description
instrumentHandle	niRFmxInstrHandle	Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function.
selectorString	char[]	Specifies a selector string) comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxLTE_BuildSignalString) function to build the selector string.
averagingEnabled	int32	Specifies whether to enable averaging for the measurement.
averagingCount	int32	Specifies the number of acquisitions used for averaging when you set the averagingEnabled parameter to true.
averagingType	int32	Specifies the averaging type for averaging multiple spectrum acquisitions. The averaged spectrum is used for the measurement.

Return Value

Name	Type	Description
status	int32	Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxLTE_GetError) function. The general meaning of the status code is as follows:

Value	Meaning
0	Success
Positive Values	Warnings
Negative Values	Errors

RFmxLTE_PVTCfgMeasurementMethod

int32 __stdcall RFmxLTE_PVTCfgMeasurementMethod (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 measurementMethod);

Purpose

Configures the method for performing the power versus time (PVT) measurement. Refer to the LTE PVT (Power Vs Time) Measurement topic for more information about measurement method.

Parameters

Input
Name	Type	Description
instrumentHandle	niRFmxInstrHandle	Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function.
selectorString	char[]	Specifies a selector string) comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxLTE_BuildSignalString) function to build the selector string.
measurementMethod	int32	Specifies the method for performing the PVT measurement. Supported Devices: PXIe-5644/5645/5646/5840/5841.

Return Value

Name	Type	Description
status	int32	Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxLTE_GetError) function. The general meaning of the status code is as follows:

Value	Meaning
0	Success
Positive Values	Warnings
Negative Values	Errors

RFmxLTE_PVTCfgOFFPowerExclusionPeriods

int32 __stdcall RFmxLTE_PVTCfgOFFPowerExclusionPeriods (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 OFFPowerExclusionBefore, float64 OFFPowerExclusionAfter);

Purpose

Configures the OFF power exclusion periods for the power versus time (PVT) measurement. Refer to the LTE PVT (Power Vs Time) Measurement topic for more information about OFF power exclusion periods.

Parameters

Input
Name	Type	Description
instrumentHandle	niRFmxInstrHandle	Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize) function.
selectorString	char[]	Specifies a selector string) comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxLTE_BuildSignalString) function to build the selector string.
OFFPowerExclusionBefore	float64	Specifies the time excluded from the OFF region before the burst. This value is expressed in seconds.
OFFPowerExclusionAfter	float64	Specifies the time excluded from the OFF region after the burst. This value is expressed in seconds.

Return Value

Name	Type	Description
status	int32	Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred.
