Syntax
int32 __stdcall RFmxNR_CHPFetchSubblockPower(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 *subblockPower)
Parameters
| Name | Direction | Type | Description |
|---|---|---|---|
| instrumentHandle | [in] | niRFmxInstrHandle | This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function. |
| selectorString | [in] | char | This parameter specifies a Selector String comprising of the signal name, result name, and subblock number. 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. The default value is "" (empty string). |
| timeout | [in] | float64 | This parameter 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. The default value is 10. |
| subblockPower | [out] | float64 * | This parameter returns the sum of powers of all the frequency bins over the integration bandwidth of the subblock. This includes the power in inter-carrier gaps within a subblock. This value is expressed in dBm. |
Returns
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 RFmxNR_GetError function.
The general meaning of the status code is as follows:
Value | Meaning |
|---|---|
0 | Success |
Positive Values | Warnings |
