Fetches the in-band emission trace and limits trace for the component carrier. In-band emission is measured as the ratio of the power in non-allocated resource blocks to the power in the allocated resource blocks averaged over the measurement interval. The IBE for various regions (general, carrier leakage, and I/Q Image) are obtained and concatenated to form a composite trace and the limits are defined in section 6.4.2.3 of 3GPP 38.101-1, and section 6.4.2.3 of 3GPP 38.101-2. The trace is not returned when there is full allocation of bandwidth, or there is clustered PUSCH or there is more than one active component carrier. Use "carrier<k>" or "subblock<n>" or "subblock<n>/carrier<k>" as the selector string to read results from this function.

Syntax

int32 __stdcall RFmxNR_ModAccFetchInBandEmissionTrace(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 timeout, float64 *x0, float64 *dx, float32 inBandEmission[], float32 inBandEmissionMask[], int32 arraySize, int32 *actualArraySize)

Parameters

NameDirectionTypeDescription
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, subblock number, and carrier 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 "subblock0/carrier0".
Example:
"subblock0/carrier0"
"signal::sig1/subblock0/carrier0"
"result::r1/subblock0/carrier0"
"signal::sig1/result::r1/subblock0/carrier0"
You can use the RFmxNR Build Carrier String function to build the selector 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.

x0[out]float64 *

This parameter returns the start point of the of the resource block.

dx[out]float64 *

This parameter returns the subcarrier spacing.

inBandEmission[out]float32

This parameter returns the in-band emission margin.

inBandEmissionMask[out]float32

This parameter returns the in-band emission mask.

arraySize[in]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[out]int32 *

Returns the actual size of the array, if you pass NULL to all output array parameters, and set the arraySize parameter to 0.

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:
