RFmxWCDMA_OBWCfgRBWFilter
int32 __stdcall RFmxWCDMA_OBWCfgRBWFilter (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 RBWAuto, float64 RBW, int32 RBWFilterType);
Purpose
Configures the RBW filter.
Parameters
| Input | ||||||||
| Name | Type | Description | ||||||
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxWCDMA_Initialize function. | ||||||
| selectorString | char[] | Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxWCDMA_BuildSignalString function to build the selector string. |
||||||
| RBWAuto | int32 | Specifies whether the measurement computes the RBW. This parameter is valid only if you set the RBWFilterType parameter to RFMXWCDMA_VAL_OBW_RBW_FILTER_TYPE_GAUSSIAN or RFMXWCDMA_VAL_OBW_RBW_FILTER_TYPE_FLAT. If you set the RBWFilterType parameter to RFMXWCDMA_VAL_OBW_RBW_FILTER_TYPE_FFT_BASED, the measurement calculates the RBW regardless of the value of this parameter.
|
||||||
| RBW | float64 | Specifies the bandwidth of the RBW filter used to sweep the acquired signal when you set the RBWAuto parameter to RFMXWCDMA_VAL_OBW_RBW_AUTO_FALSE. This parameter is valid only if you set the RBWFilterType parameter to RFMXWCDMA_VAL_OBW_RBW_FILTER_TYPE_GAUSSIAN or RFMXWCDMA_VAL_OBW_RBW_FILTER_TYPE_FLAT. This value is expressed in Hz. |
||||||
| RBWFilterType | int32 | Specifies the shape of the digital RBW filter.

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 RFmxWCDMA_GetError function. The general meaning of the status code is as follows:
