Configures the arrays of the start and stop frequencies and the sideband of an offset segment.
Use "subblock<n>" as the selector string to configure this function.

Syntax

int32 __stdcall RFmxLTE_SEMCfgOffsetFrequencyArray(niRFmxInstrHandle instrumentHandle, char selectorString[], float64 offsetStartFrequency[], float64 offsetStopFrequency[], int32 offsetSideband[], int32 numberOfElements)

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, 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 "subblock0".
Example:
"subblock0"
"signal::sig1/subblock0"
"result::r1/subblock0"
"signal::sig1/result::r1/subblock0"
You can use the RFmxLTE_BuildSubblockString function to build the selector string.

offsetStartFrequency[in]float64

This parameter specifies the array of the start frequency values of the offset segment relative to the carrier channel bandwidth edge (single-carrier) or the subblock aggregated channel bandwidth edge (multi-carrier). This value is expressed in Hz. The default value is 0.

offsetStopFrequency[in]float64

This parameter specifies the array of the stop frequency values of the offset segment relative to the carrier channel bandwidth edge (single-carrier) or the subblock aggregated channel bandwidth edge (multi-carrier). This value is expressed in Hz. The default value is 1 MHz.

offsetSideband[in]int32

This parameter specifies whether the offset segment is present on one side, or on both sides of the carrier for each offset. The default value is Both.

Description

RFMXLTE_VAL_SEM_OFFSET_SIDEBAND_NEGATIVE

0 (0x0)

Configures a lower offset segment to the left of the leftmost carrier.

RFMXLTE_VAL_SEM_OFFSET_SIDEBAND_POSITIVE

1 (0x1)

Configures an upper offset segment to the right of the rightmost carrier.

RFMXLTE_VAL_SEM_OFFSET_SIDEBAND_BOTH

2 (0x2)

Configures both the negative and the positive offset segments.

numberOfElements[in]int32

Specifies the number of elements in each array.

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:
