RFmxWCDMA_SlotPhaseFetchPhaseDiscontinuities
int32 __stdcall RFmxWCDMA_SlotPhaseFetchPhaseDiscontinuities (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 slotPhaseDiscontinuity[], int32 arraySize, int32* actualArraySize);
Purpose
Fetches the phase discontinuity values for the slot phase measurement.
Parameters
| Input | ||
| Name | Type | Description |
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWCDMA_Initialize function. |
| selectorString | char[] | Specifies a selector string comprising of the signal name and result name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxWCDMA_BuildSignalString function to build the selector string. |
| timeout | float64 | Specifies the timeout, in seconds, for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the function waits until the measurement is complete. |
| arraySize | int32 | Specifies the size of the array. Set the arraySize parameter to 0 to get the size of all the arrays in the actualArraySize parameter. |
| Output | ||
| Name | Type | Description |
| slotPhaseDiscontinuity | float64[] | Returns the difference between the first extrapolated linear chip phase of the current slot and the last extrapolated linear chip phase of the preceding slot. The extrapolation is for the exclusion period of 25us on either side of the slot boundary. If you set the
RFMXWCDMA_ATTR_SLOTPHASE_TRANSIENT_REMOVAL_ENABLED attribute to RFMXWCDMA_VAL_SLOTPHASE_TRANSIENT_REMOVAL_ENABLED_FALSE, this parameter returns the difference between the first and last linear chip phase, at each slot boundary.
This value is expressed in degrees. |
| actualArraySize | int32* | Returns the actual size of the array, if you pass NULL to all output array parameters, and set the arraySize parameter to 0. |
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 RFmxWCDMA_GetError function. The general meaning of the status code is as follows:
