int32 __stdcall RFmxLTE_SlotPowerFetchPowers (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 subframePower[], float64 subframePowerDelta[], int32 arraySize, int32* actualArraySize);
Fetches the array of Subframe Power and the Subframe Power Delta parameters over the measurement interval. A NaN is returned as subframe power delta, when the preceding slot is not occupied.
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 and the result name. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. Example: "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxLTE_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 |
subframePower | float64[] | Returns the array of subframe power values over the measurement interval. The values are expressed in dBm. |
subframePowerDelta | float64[] | Returns the array of subframe power delta values over the measurement interval. Subframe power delta values are the power difference between the two consecutive subframes. The values are expressed in dB. |
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. |
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 |
