RFmxGSM_CfgRFAttenuation
int32 __stdcall RFmxGSM_CfgRFAttenuation (niRFmxInstrHandle instrumentHandle, char channelName[], int32 RFAttenuationAuto, float64 RFAttenuationValue);
Purpose
Configures the nominal attenuation and the RFmx driver setting.
This function is a wrapper over the RFmx Instruments API, and calls the RFmxInstr_CfgRFAttenuation function.
Parameters
| Input | ||||||
| Name | Type | Description | ||||
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxGSM_Initialize function. | ||||
| channelName | char[] | Set this parameter to "" (empty string) or NULL. | ||||
| RFAttenuationAuto | int32 |
Specifies whether the RFmx driver computes the RF attenuation.
|
||||
| RFAttenuationValue | float64 | Specifies the nominal attenuation setting for all attenuators before the first mixer in the RF signal chain when you set the RFAttenuationAuto parameter to RFMXGSM_VAL_RF_ATTENUATION_AUTO_FALSE. This value is expressed in dB. | ||||
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 RFmxGSM_GetError function. The general meaning of the status code is as follows:
