Configures the number of universal terrestrial radio access (UTRA) adjacent channels of the subblock, when you set the RFMXLTE_ATTR_ACP_CONFIGURABLE_NUMBER_OF_OFFSETS_ENABLED attribute to True.
Use "subblock<n>" as the selector string to configure this function.

Syntax

int32 __stdcall RFmxLTE_ACPCfgNumberOfUTRAOffsets(niRFmxInstrHandle instrumentHandle, char selectorString[], int32 numberOfUTRAOffsets)

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 and the subblock number. If you do not specify the signal name, the default signal instance is used. The default is "" (empty string).
Example:
"subblock0"
"signal::sig1/subblock0"
You can use the RFmxLTE_BuildSubblockString function to build the selector string.

numberOfUTRAOffsets[in]int32

This parameter specifies the number of UTRA adjacent channel offsets to be configured at offset positions, when you set the ACP Configurable Number of Offset Enabled attribute to True.
In case of downlink, only 3GPP specification defined values are supported. In case of non-contiguous carrier aggregation, the configured value will be used only for the outer offsets and the offset channels in the gap region are defined as per the 3GPP specification. Offset power reference for the outer UTRA offsets are set according to the value of RFMXLTE_ATTR_ACP_EUTRA_OFFSET_DEFINITION attribute.
The default value is 1, when carrier bandwidth is 200 kHz.
The default value is 0, when the band is 46 or when you set the RFMXLTE_ATTR_ACP_EUTRA_OFFSET_DEFINITION attribute to LAA.
The default value is 2 for all other configurations.

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 RFmxLTE_GetError function.

The general meaning of the status code is as follows:
