int32 __stdcall RFmxEVDO_SlotPowerFetchPowers (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 halfSlotPower[], float64 halfSlotPowerDelta[], int32 arraySize, int32* actualArraySize);


Fetches the slot power and slot power delta for all half-slots in the measurement length. The slot power delta is the difference in power between adjacent half-slots.


Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxEVDO_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.
You can use the RFmxEVDO_BuildSignalString function to build the selector string.
timeout float64 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 function waits until the measurement is complete.
halfSlotPower float64[] Returns the array of half slot powers. This value is expressed in dBm.
halfSlotPowerDelta float64[] Returns the array of half slot power delta powers. This value is expressed in dB.
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.
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 RFmxEVDO_GetError function.

The general meaning of the status code is as follows:

Value Meaning
