RFmxLTE_SlotPhaseCfgSynchronizationModeAndInterval

int32 __stdcall RFmxLTE_SlotPhaseCfgSynchronizationModeAndInterval (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 synchronizationMode, int32 measurementOffset, int32 measurementLength);

Purpose

Configures the synchronizationMode, measurementOffset, and measurementLength parameters of SlotPhase 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.
synchronizationMode	int32	Specifies whether the measurement is performed from the frame or the slot boundary.

RFMXLTE_VAL_SLOTPHASE_SYNCHRONIZATION_MODE_FRAME (0)	The frame boundary in the acquired signal is detected, and the measurement is performed over the number of slots specified by the measurementLength parameter, starting at the offset from the boundary specified by the measurementOffset parameter. When you set the RFMXLTE_ATTR_TRIGGER_TYPE) attribute to RFMXLTE_VAL_TRIGGER_TYPE_DIGITAL_EDGE, the measurement expects a trigger at the frame boundary.
RFMXLTE_VAL_SLOTPHASE_SYNCHRONIZATION_MODE_SLOT (1)	The slot boundary the acquired signal is detected, and the measurement is performed over the number of slots specified by the measurementLength parameter, starting at the offset from the boundary specified by the measurementOffset parameter. When you set the RFMXLTE_ATTR_TRIGGER_TYPE attribute to RFMXLTE_VAL_TRIGGER_TYPE_DIGITAL_EDGE, the measurement expects a trigger at any slot boundary.

measurementOffset	int32	Specifies the measurement offset to skip from the synchronization boundary. The synchronization boundary is specified by the Synchronization Mode parameter. This value is expressed in slots.
measurementLength	int32	Specifies the number of slots to be measured. This value is expressed in slots.

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
