RFmxNR_SEMFetchUpperOffsetMarginArray
int32 __stdcall RFmxNR_SEMFetchUpperOffsetMarginArray (niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, int32 measurementStatus[], float64 margin[], float64 marginFrequency[], float64 marginAbsolutePower[], float64 marginRelativePower[], int32 arraySize, int32* actualArraySize);
Purpose
Returns an array of measurement status, margin, frequency at margin, absolute, and relative power at margin for upper offset segments. The relative power is relative to the total aggregated power.
Use "subblock<n>" as the selector string to read results from this function.
Parameters
| Input | ||||||
| Name | Type | Description | ||||
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxNR_Initialize function. | ||||
| selectorString | char[] | 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. Example: "subblock0" "signal::sig1/subblock0" "result::r1/subblock0" "signal::sig1/result::r1/subblock0" You can use the RFmxNR_BuildSubblockString 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 | ||||
| measurementStatus | int32[] | Returns an array of the measurement status indicating whether the power before and after the burst is within the standard defined limit.
|
||||
| margin | float64[] | Returns an array of the margin from the absolute limit mask for upper (positive) offset. Margin is defined as the minimum difference between the spectrum and the limit mask. This value is expressed in dB.
|
||||
| marginFrequency | float64[] | Returns an array of the frequency at which the margin occurs in the upper offset. This value is expressed in Hz.
|
||||
| marginAbsolutePower | float64[] | Returns an array of the power at which the margin occurs in the upper offset segment. This value is expressed in dBm.
|
||||
| marginRelativePower | float64[] | Returns an array of the power at which the margin occurs in the upper (positive) offset segment. This value is 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. | ||||
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 RFmxNR_GetError function. The general meaning of the status code is as follows:
